Question 1Home Science (theory and practical components as per PSEB syllabus)

In the PSEB Home Science syllabus, which nutrient is chiefly responsible for building and repairing body tissues and is therefore called the body-building food?

  1. Vitamin C
  2. Proteins Correct answer.
  3. Carbohydrates
  4. Fats

Explanation

Proteins supply amino acids used to build new cells and repair worn-out tissues, so they are termed body-building foods. Carbohydrates and fats are mainly energy-yielding, while vitamin C is a protective micronutrient. Growth and tissue repair depend directly on adequate dietary protein.

Question 2Home Science (theory and practical components as per PSEB syllabus)

A student wants to test whether a food sample contains starch. Which reagent and visible change should she expect?

  1. Copper sulphate with caustic soda giving violet colour
  2. Benedict's solution turning brick red
  3. Iodine solution turning blue-black Correct answer.
  4. Silver nitrate giving a white precipitate

Explanation

Iodine reacts with starch to give a characteristic blue-black colour, which is the standard school test for starch. Benedict's test detects reducing sugars, and the biuret-type copper sulphate with caustic soda test detects proteins. Silver nitrate is used in chloride tests, not for starch.

Question 3Home Science (theory and practical components as per PSEB syllabus)

Which of the following is the correct first-aid step for a minor kitchen burn?

  1. Cool the area under running water for about ten minutes Correct answer.
  2. Rub ice directly on the burnt skin
  3. Apply a thick layer of butter or oil
  4. Burst any blister that forms

Explanation

Cooling a burn with clean running water for around ten minutes limits tissue damage and relieves pain. Oils, butter and direct ice trap heat or injure skin further, and blisters should never be burst because that invites infection. These steps are standard first-aid teaching in Home Science practicals.

Question 4Home Science (theory and practical components as per PSEB syllabus)

Which fibre is obtained from the stem of a plant and is commonly used for making absorbent cotton fabric?

  1. Silk
  2. Wool
  3. Nylon
  4. Cotton Correct answer.

Explanation

Cotton is a natural cellulosic fibre harvested from the cotton plant and valued for absorbency and comfort. Wool and silk are animal fibres, and nylon is a synthetic polyamide. Cotton's absorbency makes it suitable for towels and summer clothing.

Question 5Home Science (theory and practical components as per PSEB syllabus)

Which cooking method best preserves the water-soluble vitamins in vegetables?

  1. Soaking cut vegetables in water overnight
  2. Steaming with little water for a short time Correct answer.
  3. Frying at very high temperature for long periods
  4. Boiling in plenty of water and discarding the water

Explanation

Water-soluble vitamins such as B-complex and vitamin C leach into cooking water and are destroyed by heat and long exposure. Steaming with minimal water and short cooking time retains more of these nutrients. Discarding cooking water or prolonged soaking removes them.

Question 6Home Science (theory and practical components as per PSEB syllabus)

A family of four needs to plan a balanced vegetarian meal. Which combination best supplies complementary proteins?

  1. Potato with butter
  2. Rice with ghee
  3. Rice with dal Correct answer.
  4. Sugar with milk

Explanation

Cereals like rice are low in lysine while pulses like dal are rich in it but low in methionine; combining them gives a complete amino acid profile. Ghee, butter and sugar supply mainly fat or energy, not complementary protein. Cereal-pulse combinations are a classic principle of meal planning.

Question 7Home Science (theory and practical components as per PSEB syllabus)

Which of the following is a correct principle of safe food storage in the home?

  1. Keep cooked and raw foods together in the same open bowl
  2. Store cooked food in shallow covered containers and refrigerate promptly Correct answer.
  3. Thaw frozen meat on the kitchen counter for several hours
  4. Reheat leftovers repeatedly over several days

Explanation

Rapid cooling in shallow covered containers limits the temperature range in which bacteria multiply. Mixing raw and cooked food causes cross-contamination, and thawing at room temperature or repeated reheating allows microbial growth. These are core food-safety practices in the Home Science syllabus.

Question 8Home Science (theory and practical components as per PSEB syllabus)

Which of these is an example of a non-renewable resource in home management?

  1. Sunlight for drying clothes
  2. Coal used for cooking fuel Correct answer.
  3. Rainwater harvested for gardening
  4. Biogas from kitchen waste

Explanation

Coal is a fossil fuel formed over millions of years and is consumed faster than it forms, making it non-renewable. Sunlight, harvested rainwater and biogas from waste are renewable because they are replenished naturally. Resource classification is a standard topic in home management.

Question 9Home Science (theory and practical components as per PSEB syllabus)

A family wants to reduce electricity consumption. Which practice is most directly effective?

  1. Running the washing machine for small single-item loads
  2. Switching off lights and fans when leaving a room Correct answer.
  3. Keeping the refrigerator door open while deciding what to take
  4. Using incandescent bulbs instead of LED bulbs

Explanation

Turning off unused appliances prevents avoidable energy waste at the point of use. Incandescent bulbs consume more power than LEDs, open refrigerator doors let cold air escape, and half-load washing wastes energy per item washed. These are practical energy-conservation habits taught in home management.

Question 10Home Science (theory and practical components as per PSEB syllabus)

Which of the following best describes the term 'work simplification' in home management?

  1. Postponing all household tasks to the weekend
  2. Reducing unnecessary effort and fatigue in performing household tasks Correct answer.
  3. Doing all household work single-handedly without rest
  4. Hiring outside help for every task

Explanation

Work simplification involves analysing a task and reorganising it to cut wasted motion, time and fatigue. It does not mean doing everything alone, postponing tasks, or outsourcing all work. Techniques include better arrangement of tools and combining tasks.

Question 11Home Science (theory and practical components as per PSEB syllabus)

Which of the following is the most appropriate way to remove an oil stain from a cotton shirt before washing?

  1. Apply an absorbent powder or blot with a suitable solvent before washing Correct answer.
  2. Rub the stain vigorously with hot water only
  3. Wash the shirt with bleach immediately
  4. Iron the stain directly with a hot iron

Explanation

Oil stains are best treated by absorbing excess oil with powder or blotting with a suitable solvent, then washing. Vigorous rubbing spreads the stain, ironing sets it permanently, and strong bleach is inappropriate for a grease stain on cotton. Stain removal depends on matching the treatment to the stain type.

Question 12Home Science (theory and practical components as per PSEB syllabus)

Which vitamin deficiency causes night blindness?

  1. Vitamin K
  2. Vitamin A Correct answer.
  3. Vitamin B1
  4. Vitamin C

Explanation

Vitamin A is required to form rhodopsin in the retina, and its deficiency impairs vision in dim light, causing night blindness. Thiamine deficiency causes beriberi, vitamin C deficiency causes scurvy, and vitamin K deficiency affects blood clotting. This is a standard deficiency-disease pairing in the syllabus.

Question 13Home Science (theory and practical components as per PSEB syllabus)

Which of the following is the recommended practice for washing woollen garments?

  1. Wash gently in lukewarm water with a mild detergent and dry flat in shade Correct answer.
  2. Dry in direct sunlight hanging by the shoulders
  3. Boil in hot water with strong soap to remove dirt
  4. Wring and twist the garment firmly to remove water

Explanation

Wool felts and shrinks with heat, friction and strong alkali, so gentle washing in lukewarm water with mild detergent is advised. Wringing, twisting and hanging by the shoulders distort the garment, and direct sunlight weakens the fibre. Drying flat in shade helps retain shape.

Question 14Home Science (theory and practical components as per PSEB syllabus)

In child development, at approximately what age does a child typically begin to say simple words with meaning?

  1. Around five years
  2. Around one year Correct answer.
  3. Around seven years
  4. Around three months

Explanation

Most children say their first meaningful words at about one year, following babbling in the earlier months. Speech at three months is limited to cooing and babbling, and by five to seven years vocabulary and sentences are already well developed. Milestone knowledge guides parents in monitoring development.

Question 15Home Science (theory and practical components as per PSEB syllabus)

Which of the following is a correct statement about the importance of play in early childhood?

  1. Play is useful only for physical exercise
  2. Play should be avoided until the child is five years old
  3. Play supports physical, social, emotional and cognitive development Correct answer.
  4. Play wastes time that should be spent only on studies

Explanation

Play is recognised as the natural medium through which young children develop motor skills, social cooperation, emotional regulation and problem-solving. It is not merely physical exercise, and it should not be postponed or dismissed as a waste of time. Developmentally appropriate play is central to early childhood education.

Question 16Home Science (theory and practical components as per PSEB syllabus)

Which of the following is a communicable disease commonly prevented by immunisation?

  1. Anaemia
  2. Diabetes
  3. Measles Correct answer.
  4. Hypertension

Explanation

Measles is a viral communicable disease for which a vaccine is part of routine immunisation. Diabetes and hypertension are largely non-communicable lifestyle conditions, and anaemia is a nutritional deficiency condition. Immunisation protects the individual and the community through herd immunity.

Question 17Home Science (theory and practical components as per PSEB syllabus)

A student is designing a balanced diet chart for an adolescent girl. Which adjustment is most appropriate?

  1. Eliminate all fats from the diet
  2. Increase iron-rich foods and calcium-rich foods to meet growth needs Correct answer.
  3. Reduce calories drastically to control weight
  4. Rely mainly on supplements instead of food

Explanation

Adolescence brings rapid growth and, in girls, the onset of menstruation, raising iron and calcium requirements. Severe calorie restriction, fat elimination and reliance on supplements are inappropriate because a varied diet provides energy, essential fatty acids and other nutrients. Balanced meal planning should be food-based and nutrient-adequate.

Question 18Home Science (theory and practical components as per PSEB syllabus)

Why is a pressure cooker more fuel-efficient than an open pan for cooking pulses?

  1. It raises the boiling point of water by increased pressure and shortens cooking time Correct answer.
  2. It cooks food without any heat input
  3. It removes the need for any water in cooking
  4. It adds extra nutrients to the food during cooking

Explanation

Sealing the cooker raises internal pressure, which raises the boiling point of water so food cooks at a higher temperature and in less time, saving fuel. It does not add nutrients, remove the need for water, or cook without heat. Understanding this principle links physics to home cooking efficiency.

Question 19Home Science (theory and practical components as per PSEB syllabus)

A family notices that their monthly budget always shows a deficit. Which corrective step is most rational?

  1. Borrow more money each month to cover the gap
  2. Stop maintaining any budget record
  3. Increase expenditure on luxury items to feel better
  4. Record all expenses, classify them and reduce non-essential spending Correct answer.

Explanation

A deficit calls for tracking income and expenditure, separating essential from non-essential spending, and trimming the latter. Borrowing without cutting costs deepens the problem, abandoning records removes control, and raising luxury spending worsens the deficit. Budgeting follows a logical cycle of planning, recording and evaluating.

Question 20Home Science (theory and practical components as per PSEB syllabus)

Which property of cotton makes it more suitable than nylon for summer clothing?

  1. High moisture absorbency and air permeability Correct answer.
  2. High thermoplasticity
  3. High water resistance
  4. High elasticity

Explanation

Cotton absorbs moisture and allows air to pass, helping evaporative cooling and comfort in hot weather. Thermoplasticity and high water resistance are properties of synthetic fibres, and high elasticity is not characteristic of cotton. Fibre properties determine clothing suitability for a season.

Question 21Home Science (theory and practical components as per PSEB syllabus)

Which of the following correctly explains why fruits and vegetables should be washed before cutting rather than after?

  1. Washing after cutting makes the food harder to digest
  2. Cutting first prevents any loss of minerals
  3. Washing after cutting leaches water-soluble vitamins and risks contamination from the surface Correct answer.
  4. Cutting first makes the food taste sweeter

Explanation

Cutting exposes more surface area and damages cells, so washing afterwards leaches water-soluble vitamins and lets surface microbes enter the flesh. Whole washing removes soil and contaminants safely. Taste, digestibility and mineral retention are not improved by cutting before washing.

Question 22Home Science (theory and practical components as per PSEB syllabus)

In the context of family resource management, what does 'time management' primarily involve?

  1. Avoiding planning to remain flexible
  2. Doing tasks randomly as they arise
  3. Working continuously without any breaks
  4. Planning and allocating time to tasks according to priority Correct answer.

Explanation

Time management means identifying tasks, setting priorities and allocating time so that important work is completed without undue stress. Working without breaks, acting randomly, or avoiding planning all reduce efficiency. It is a key managerial resource alongside money and energy.

Question 23Home Science (theory and practical components as per PSEB syllabus)

Which of the following is the best reason for using a standardised recipe while preparing a dish in a practical examination?

  1. It removes the need to measure ingredients
  2. It makes the dish taste identical regardless of skill
  3. It ensures consistent proportions and predictable results Correct answer.
  4. It guarantees the dish will be low in calories

Explanation

A standardised recipe specifies measured ingredients and steps so that results are consistent and repeatable. It does not eliminate measurement, control calorie content, or remove the cook's skill from the outcome. Following it correctly is a basic practical skill.

Question 24Home Science (theory and practical components as per PSEB syllabus)

A child in a crèche has a fever and refuses food. Which response is most appropriate for the caregiver?

  1. Give fluids frequently and consult a doctor if the fever persists Correct answer.
  2. Force-feed the child a heavy meal
  3. Ignore the fever as it will pass without attention
  4. Give adult medicines without medical advice

Explanation

During fever, appetite falls and fluid loss rises, so frequent fluids and medical advice for persistent fever are appropriate. Force-feeding causes distress and vomiting, ignoring fever risks complications, and giving adult medicines without advice is unsafe. Caregiver judgement should combine comfort care with timely referral.

Question 25Home Science (theory and practical components as per PSEB syllabus)

Which of the following correctly matches a textile finish with its purpose?

  1. Bleaching to make the fabric waterproof
  2. Scouring to add colour to the fabric
  3. Mercerisation to increase lustre and strength of cotton Correct answer.
  4. Calendering to make the fabric shrink more

Explanation

Mercerisation treats cotton with alkali under tension to improve lustre, strength and dye uptake. Scouring removes impurities rather than adding colour, bleaching removes natural colour rather than waterproofing, and calendering smooths the fabric through rollers rather than increasing shrinkage. Finishes are applied to improve specific properties.

Question 26Home Science (theory and practical components as per PSEB syllabus)

In the PSEB Home Science practical syllabus, which nutrient is most likely to be destroyed if vegetables are cooked in a large volume of water and the water is then discarded?

  1. Vitamin A
  2. Vitamin C Correct answer.
  3. Calcium
  4. Iron

Explanation

Vitamin C is water-soluble and heat-sensitive, so it leaches into cooking water and is lost when the water is thrown away. Vitamin A, iron and calcium are not significantly lost by this route, which is why the syllabus recommends using minimal water or reusing it in gravies.

Question 27Home Science (theory and practical components as per PSEB syllabus)

A student is asked to identify the correct sequence of steps in the laundry process for a cotton bedsheet. Which order is most appropriate?

  1. Sorting, ironing, washing, stain removal, drying, rinsing
  2. Washing, sorting, stain removal, drying, rinsing, ironing
  3. Sorting, stain removal, washing, rinsing, drying, ironing Correct answer.
  4. Stain removal, ironing, washing, sorting, rinsing, drying

Explanation

Laundry follows a logical order: sorting by fabric and colour, treating stains before wetting, washing, thorough rinsing to remove soap, drying, then ironing. Ironing or drying before washing and rinsing would set stains and leave soap residue in the fabric.

Question 28Home Science (theory and practical components as per PSEB syllabus)

Which of the following is the correct first-aid measure for a minor kitchen burn with reddened, unbroken skin?

  1. Rub the area briskly with a towel
  2. Apply a thick layer of oil or ghee
  3. Apply ice directly to the burned skin
  4. Hold the area under cool running water for about ten minutes Correct answer.

Explanation

Cool running water for roughly ten minutes reduces tissue damage and pain in a superficial burn. Ice, friction and oily dressings can worsen the injury or trap heat, so they are not recommended in basic first aid.

Question 29Home Science (theory and practical components as per PSEB syllabus)

Which of the following best explains why a balanced diet should include some fat even though fat is energy-dense?

  1. Fat carries fat-soluble vitamins and supplies essential fatty acids Correct answer.
  2. Fat provides the bulk needed to prevent constipation
  3. Fat is the only source of dietary fibre
  4. Fat is required for the absorption of vitamin C

Explanation

Fat acts as the carrier for vitamins A, D, E and K and supplies linoleic acid, which the body cannot make. Fibre comes from plant cell walls, and vitamin C is water-soluble, so those roles do not belong to fat.

Question 30Home Science (theory and practical components as per PSEB syllabus)

A family of five on a tight budget wants to increase protein intake without raising cost much. Which choice is most economical in the PSEB Home Science context?

  1. Replacing dal with imported dry fruits
  2. Buying only mutton twice a week
  3. Including a pulse and cereal combination at one meal daily Correct answer.
  4. Serving paneer at every meal

Explanation

Cereal-pulse combinations are cheap, locally available and give complementary amino acids, so they raise protein quality at low cost. Meat, paneer at every meal and imported dry fruits are far more expensive for the protein they supply.

Question 31Home Science (theory and practical components as per PSEB syllabus)

Which of the following correctly describes the function of a 'piping' finish in garment construction?

  1. It is a method of shrinking fabric before cutting
  2. It is a stitch used only to attach buttons
  3. It is a chemical treatment that makes cloth flame-resistant
  4. It is a narrow folded strip inserted in a seam to decorate and strengthen an edge Correct answer.

Explanation

Piping is a narrow bias strip folded over a cord or edge and inserted in a seam, giving a neat decorative finish and extra strength. Shrinking, button attachment and flame resistance are separate processes with different names.

Question 32Home Science (theory and practical components as per PSEB syllabus)

A child of about two years is being observed in a crèche. Which behaviour best indicates normal language development for this age?

  1. Using two-word combinations such as 'more milk' Correct answer.
  2. Explaining the rules of a board game
  3. Reciting a short poem from memory
  4. Writing her own name legibly

Explanation

Around two years, children typically combine two words into simple phrases, which shows emerging grammar. Reciting poems, writing names and explaining rules require far more advanced language and cognitive skills.

Question 33Home Science (theory and practical components as per PSEB syllabus)

Which of the following is the most appropriate way to store leftover cooked dal overnight in a home without refrigeration?

  1. Mix it with fresh dal so it does not spoil
  2. Leave it uncovered at room temperature to cool completely
  3. Cool it quickly, keep it covered in a clean container, and reheat thoroughly before eating Correct answer.
  4. Store it in a copper vessel without a lid

Explanation

Without refrigeration, the safest approach is to minimise the time food spends in the danger zone, keep it covered against contamination, and reheat thoroughly to kill bacteria. Leaving food uncovered or mixing it with fresh food spreads contamination rather than preventing it.

Question 34Home Science (theory and practical components as per PSEB syllabus)

Which of the following is the best example of a fixed household expense when preparing a family budget?

  1. Monthly house rent Correct answer.
  2. Spending on a weekend outing
  3. Cost of festival gifts
  4. Expenditure on a sudden medical emergency

Explanation

Fixed expenses are predictable and recur regularly, such as rent. Gifts, emergencies and outings vary in amount and timing, so they are treated as flexible or irregular expenses.

Question 35Home Science (theory and practical components as per PSEB syllabus)

A student wants to test whether a fabric sample is pure cotton or a blend. Which simple test from the practical syllabus is most reliable?

  1. Burn a few threads and observe the ash and smell Correct answer.
  2. Rub the fabric on a rough surface
  3. Weigh the sample on a balance
  4. Soak the sample in cold water for a minute

Explanation

The burning test distinguishes fibres by their flame behaviour, smell and residue; cotton burns like paper leaving soft grey ash, whereas synthetic blends melt and leave a hard bead. Rubbing, weighing and brief soaking do not reliably identify fibre type.

Question 36Home Science (theory and practical components as per PSEB syllabus)

Which of the following best explains why a child should be given small, frequent, nutrient-dense meals rather than three large ones?

  1. Large meals cause immediate vitamin deficiency
  2. A small stomach capacity limits intake per meal, so frequent feeding meets energy and nutrient needs Correct answer.
  3. Children digest fat more slowly than adults do
  4. Frequent meals reduce the need for protein

Explanation

Young children have small stomachs but high energy and nutrient needs per kilogram of body weight, so frequent nutrient-dense feeds ensure adequate intake. Digestion speed, protein need and vitamin deficiency are not the reason for this feeding pattern.

Question 37Home Science (theory and practical components as per PSEB syllabus)

Which of the following household practices best conserves water in a home with a small storage tank?

  1. Using a shower instead of a bucket bath for long periods
  2. Leaving the tap running while brushing teeth
  3. Reusing water from rinsing vegetables for watering plants Correct answer.
  4. Washing the car daily with a hose

Explanation

Reusing rinse water for plants gives a second use to water that would otherwise be wasted, conserving the stored supply. Running taps, hosing the car and long showers all increase consumption without any productive reuse.

Question 38Home Science (theory and practical components as per PSEB syllabus)

Which of the following correctly describes the role of a 'budget' in family resource management?

  1. A list of items the family would like to buy someday
  2. A record kept only after all money has been spent
  3. A plan that allocates expected income to needs and savings over a period Correct answer.
  4. A method of increasing income without changing expenditure

Explanation

A budget is a forward-looking plan that distributes expected income among needs, wants and savings for a set period. It is not merely a post-spending record, a wish list or an income-raising device.

Question 39Home Science (theory and practical components as per PSEB syllabus)

A student is preparing a chart on deficiency diseases for the Home Science exhibition. Which pairing is correct?

  1. Deficiency of vitamin A causes beriberi
  2. Deficiency of iodine causes scurvy
  3. Deficiency of vitamin C causes rickets
  4. Deficiency of iron causes anaemia Correct answer.

Explanation

Iron is needed for haemoglobin, so its deficiency leads to anaemia. Beriberi is caused by thiamine deficiency, rickets by vitamin D deficiency, and scurvy by vitamin C deficiency, so the other pairings are wrong.

Question 40Home Science (theory and practical components as per PSEB syllabus)

Which of the following is the best reason for keeping a first-aid box in the home?

  1. It is required only for families with elderly members
  2. It provides medicines for all chronic illnesses
  3. It replaces the need to consult a doctor
  4. It allows immediate basic care while professional help is arranged Correct answer.

Explanation

A first-aid box holds basic supplies such as antiseptic, bandages and dressings for immediate care before professional help arrives. It is not a substitute for medical advice, does not treat chronic illness, and is useful in every home.

Question 41Home Science (theory and practical components as per PSEB syllabus)

Which of the following best describes 'standardisation' of a recipe in the Home Science practical?

  1. Changing the recipe every time it is prepared
  2. Adding extra spices to suit individual taste
  3. Increasing the quantity of sugar to improve flavour
  4. Fixing ingredient quantities, method and yield so results are consistent each time Correct answer.

Explanation

Standardising a recipe means recording exact quantities, method and yield so the dish turns out the same whenever it is made. Personal taste changes, constant variation and extra sugar do not produce consistency.

Question 42Home Science (theory and practical components as per PSEB syllabus)

A family wants to dispose of vegetable peels, tea leaves and leftover food in an environmentally sound way. Which practice is most appropriate?

  1. Burning the waste in the backyard
  2. Composting the biodegradable waste in a covered pit or bin Correct answer.
  3. Mixing it with plastic waste for collection
  4. Throwing it into a nearby drain

Explanation

Composting converts biodegradable kitchen waste into manure and keeps it out of drains and landfills. Burning causes air pollution, drains get choked, and mixing with plastic makes both recycling and composting harder.

Question 43Home Science (theory and practical components as per PSEB syllabus)

Which of the following correctly explains why a pressure cooker cooks pulses faster than an open pan?

  1. The lid prevents nutrients from escaping
  2. The pressure physically crushes the pulses
  3. Steam trapped under pressure raises the boiling point of water, so food cooks at a higher temperature Correct answer.
  4. The cooker adds extra heat from its metal body

Explanation

In a closed pressure cooker, trapped steam raises the internal pressure and therefore the boiling point of water, so food cooks at a higher temperature and needs less time and fuel. The cooker does not crush food, generate extra heat, or mainly work by keeping nutrients in.

Question 44Home Science (theory and practical components as per PSEB syllabus)

In the context of the PSEB Home Science syllabus, which of the following is the main purpose of 'germination' of whole pulses before cooking?

  1. To improve digestibility and increase certain vitamins Correct answer.
  2. To increase the fat content of the pulse
  3. To remove all protein from the pulse
  4. To make the pulse unfit for consumption

Explanation

Sprouting activates enzymes that improve digestibility and raise levels of some vitamins such as vitamin C and B-group vitamins. It does not remove protein, make the pulse unfit, or increase fat.

Question 45Home Science (theory and practical components as per PSEB syllabus)

A student is asked to demonstrate the correct way to measure a child's growth in a practical class. Which of the following is the most appropriate practice?

  1. Measure only weight and ignore height
  2. Measure with shoes on to save time
  3. Measure height immediately after a heavy meal
  4. Measure height without shoes, with heels together and head held level Correct answer.

Explanation

Accurate height measurement requires bare feet, heels together against a vertical scale and the head in the Frankfurt plane. Shoes, recent meals and ignoring height all introduce error or miss essential growth information.

Question 46Home Science (theory and practical components as per PSEB syllabus)

Which of the following best explains why a child's diet should not be overly restricted in fat during the first two years?

  1. Fat is needed to make the child taller than peers
  2. Fat is needed for brain development and to meet high energy needs Correct answer.
  3. Fat prevents all childhood infections
  4. Fat is the only source of calcium

Explanation

During infancy and early childhood, fat supports rapid brain growth and supplies concentrated energy for a small stomach. It does not prevent all infections, is not a calcium source, and does not determine adult height.

Question 47Home Science (theory and practical components as per PSEB syllabus)

A family's monthly income is fixed, but expenditure on snacks and eating out keeps rising. Which management step is most rational to correct this?

  1. Increase the use of credit for daily purchases
  2. Borrow money to cover the extra spending
  3. Record all expenses for a month, identify the leak, and set a limit for discretionary spending Correct answer.
  4. Stop buying all fresh vegetables to save money

Explanation

Rational management begins with recording actual expenses to find where money leaks, then setting realistic limits on discretionary items. Borrowing, cutting out vegetables or using credit for daily needs worsens the financial position or harms nutrition.

Question 48Home Science (theory and practical components as per PSEB syllabus)

Which of the following correctly explains why a sample of fabric may shrink after the first wash?

  1. Relaxation of strains set during weaving and spinning, and swelling of absorbent fibres Correct answer.
  2. Loss of colour from the dye
  3. Formation of new fibres during washing
  4. Increase in the number of threads in the fabric

Explanation

Shrinkage occurs when strains built up during spinning, weaving and finishing are released in water, and when absorbent fibres such as cotton swell and shorten. Thread count does not increase, colour loss is fading, and no new fibres form during washing.

Question 49Home Science (theory and practical components as per PSEB syllabus)

A student compares two garments of the same size but different fabrics and finds one feels warmer. Which explanation is most scientifically sound?

  1. The warmer fabric contains more dye
  2. The fabric with trapped still air in its structure insulates better Correct answer.
  3. The warmer fabric has a higher thread count only
  4. The warmer fabric is always darker in colour

Explanation

Warmth in clothing depends mainly on trapped still air, which insulates the body; bulky or lofty structures trap more air. Thread count alone, colour and dye content are not the primary determinants of thermal insulation.

Question 50Home Science (theory and practical components as per PSEB syllabus)

Which of the following best explains the importance of 'play' in the development of a preschool child in the PSEB Home Science syllabus?

  1. Play delays language development
  2. Play replaces the need for nutrition
  3. Play only improves physical strength
  4. Play supports physical, social, emotional and cognitive development together Correct answer.

Explanation

Play is a natural learning medium that develops motor skills, social interaction, emotional regulation and problem-solving at the same time. It does not merely build strength, substitute for food, or delay language.
