Question 1Home Economics

Which nutrient is the body's main source of quick energy and is found abundantly in bread, pasta and potatoes?

  1. Calcium
  2. Carbohydrate Correct answer.
  3. Vitamin C
  4. Protein

Explanation

Carbohydrates are broken down into glucose, which cells use as their primary fuel, and starchy foods such as bread, pasta and potatoes are the richest everyday sources. Protein and minerals serve structural and regulatory roles rather than supplying quick energy.

Question 2Home Economics

A home economist recommends storing raw chicken on the bottom shelf of a refrigerator. What is the main food-safety reason for this practice?

  1. It prevents juices from dripping onto ready-to-eat foods below Correct answer.
  2. It keeps the chicken at a lower temperature than the rest of the fridge
  3. It speeds up the cooking time of the chicken later
  4. It allows the chicken to absorb moisture from the air

Explanation

Raw poultry can carry pathogens such as Campylobacter and Salmonella, and any drip onto cooked or ready-to-eat food would cause cross-contamination. Placing it on the lowest shelf means gravity carries any leakage away from other foods.

Question 3Home Economics

Which fibre type dissolves in water, forms a gel in the gut and helps lower blood cholesterol?

  1. Insoluble fibre from wheat bran
  2. Lignin
  3. Cellulose
  4. Soluble fibre such as pectin Correct answer.

Explanation

Soluble fibre, found in oats, pulses and fruit pectin, forms a viscous gel that slows glucose absorption and binds bile acids, lowering blood cholesterol. Insoluble fibres such as cellulose and lignin add bulk and speed transit instead.

Question 4Home Economics

A family of four wants to reduce food waste. Which practice best supports this aim in the home?

  1. Storing all fruit and vegetables together in one sealed bag
  2. Planning weekly meals and writing a shopping list from that plan Correct answer.
  3. Buying larger packs because the unit price is always lower
  4. Buying only items on the top shelf of the supermarket

Explanation

Meal planning linked to a shopping list means food is bought with a specific use in mind, so less is left to spoil. Buying in bulk or mixing produce indiscriminately often increases spoilage and therefore waste.

Question 5Home Economics

Which statement correctly describes the function of the shortfall nutrient iron in the diet?

  1. It regulates fluid balance across cell membranes
  2. It acts as an antioxidant vitamin
  3. It is the main mineral in tooth enamel
  4. It forms part of haemoglobin, which carries oxygen in the blood Correct answer.

Explanation

Iron is a component of haemoglobin in red blood cells, where it binds oxygen for transport around the body. Deficiency leads to iron-deficiency anaemia with tiredness and pallor.

Question 6Home Economics

In the design process used when making a textile product, what is the purpose of producing a toile or sample garment?

  1. To test fit and construction before cutting the final fabric Correct answer.
  2. To calculate the final selling price of the product
  3. To replace the need for a paper pattern
  4. To decorate the finished garment with embroidery

Explanation

A toile is a trial version, often in calico, that lets the maker check fit, drape and construction so mistakes are corrected before expensive final fabric is cut. It is a testing stage, not a costing or decorative one.

Question 7Home Economics

Which laundry practice is most suitable for a woollen jumper labelled 'hand wash, cool'?

  1. Washing in cool water with a mild neutral detergent and drying flat Correct answer.
  2. Tumble drying on a high heat setting
  3. Machine washing at 60 °C with biological powder
  4. Boiling with strong soda to remove all odours

Explanation

Wool fibres have overlapping scales that interlock and shrink when exposed to heat, agitation and alkali, so cool water with a mild neutral detergent and flat drying protects shape. High temperatures and strong alkalis cause felting.

Question 8Home Economics

Which of these is a renewable source of household energy?

  1. Kerosene
  2. Coal
  3. Solar photovoltaic panels Correct answer.
  4. Natural gas

Explanation

Solar energy is replenished continuously by sunlight and produces no direct carbon emissions during use. Natural gas, kerosene and coal are fossil fuels formed over millions of years and are therefore finite.

Question 9Home Economics

A family's electricity bill is high. Which change would most directly reduce the energy used by the refrigerator?

  1. Setting the thermostat to the coldest possible setting
  2. Painting the kitchen walls a lighter colour
  3. Opening the door more often to check what is inside
  4. Keeping the fridge away from the cooker and defrosting it regularly Correct answer.

Explanation

A fridge uses more energy when it must remove heat from warm surroundings or when ice build-up reduces heat transfer. Siting it away from heat sources and defrosting keeps the compressor working efficiently.

Question 10Home Economics

Which of the following best describes the term 'unit price' on a supermarket shelf label?

  1. The total price paid at the till including VAT
  2. The price of the most expensive item in the range
  3. The price after a loyalty-card discount is applied
  4. The cost per standard measure, such as per kilogram, used to compare products Correct answer.

Explanation

A unit price expresses cost per kilogram, per litre or per 100 g, allowing shoppers to compare value between differently sized packs. It is a comparison tool rather than the final amount paid.

Question 11Home Economics

When comparing two similar kettles, which consumer right protects a buyer whose kettle stops working after three weeks?

  1. The right to redress for faulty goods Correct answer.
  2. The right to a healthy environment
  3. The right to choose any brand
  4. The right to consumer education

Explanation

Consumer protection law gives buyers a right to redress, meaning repair, replacement or refund when goods are faulty or not fit for purpose. The other listed rights concern choice, information and environmental quality.

Question 12Home Economics

Which food group should make up the largest proportion of a balanced main meal according to healthy eating guidance?

  1. Foods high in fat and sugar
  2. Protein foods such as meat and fish
  3. Dairy foods such as cheese
  4. Starchy carbohydrates such as rice, bread or pasta Correct answer.

Explanation

Healthy eating models place starchy carbohydrates as the base of the diet because they supply energy, fibre and B vitamins and should feature at every meal. Fat- and sugar-rich foods sit at the top and should be eaten sparingly.

Question 13Home Economics

A recipe for four people uses 300 g of pasta. How much pasta is needed if the recipe is scaled to serve six people?

  1. 450 g Correct answer.
  2. 400 g
  3. 350 g
  4. 500 g

Explanation

The recipe uses 300 g for four servings, so one serving needs 75 g. Multiplying 75 g by six servings gives 450 g, a straightforward use of proportional reasoning in recipe adaptation.

Question 14Home Economics

Which cooking method would best preserve water-soluble vitamins in vegetables?

  1. Soaking in cold water overnight before cooking
  2. Boiling in a large volume of water for a long time
  3. Steaming until just tender Correct answer.
  4. Frying in deep oil

Explanation

Vitamin C and the B group dissolve in water and are destroyed by heat and leaching, so short cooking with minimal water such as steaming retains more. Long boiling and overnight soaking both leach vitamins into the water.

Question 15Home Economics

What is the main function of baking powder in a sponge cake mixture?

  1. It preserves the cake and extends shelf life
  2. It binds the fat and flour together
  3. It releases carbon dioxide to make the cake rise Correct answer.
  4. It sweetens the cake and adds colour

Explanation

Baking powder contains bicarbonate of soda and an acid that react in the presence of moisture and heat to release carbon dioxide, which expands the batter and gives a light texture. Sweetening, binding and preserving are done by other ingredients.

Question 16Home Economics

A cake has a coarse, uneven texture with large holes and a sunken centre. Which cause is most likely?

  1. The oven was set too low and the cake was underbaked
  2. Too much raising agent was used Correct answer.
  3. Too little raising agent was used
  4. The sugar was omitted from the recipe

Explanation

Excess raising agent produces too much gas, creating large irregular holes, and the structure collapses as it cools, giving a sunken centre. Too little raising agent gives a flat, heavy cake instead.

Question 17Home Economics

Which statement about the care label symbol showing a tub of water with a hand inside is correct?

  1. The item should not be washed at all
  2. The item should be washed by hand only Correct answer.
  3. The item must be dry cleaned only
  4. The item may be machine washed at any temperature

Explanation

The hand-in-tub symbol means the garment is suitable for hand washing, usually in lukewarm water with gentle handling. A crossed-out tub means do not wash, and a circle indicates dry cleaning instructions.

Question 18Home Economics

Why is a cotton bath towel more absorbent than a polyester one of similar thickness?

  1. Cotton is a synthetic fibre with a smooth surface
  2. Cotton fibres have hydroxyl groups that attract water molecules Correct answer.
  3. Polyester has a higher moisture regain than cotton
  4. Polyester fibres are naturally hollow and repel water

Explanation

Cotton is a cellulose fibre with many hydroxyl groups on its polymer chains, which form hydrogen bonds with water and draw it into the fibre. Polyester is hydrophobic and has very low moisture regain, so it sheds water.

Question 19Home Economics

Which practice best reduces the risk of cross-contamination when preparing a packed lunch?

  1. Wiping the knife on a tea towel between foods
  2. Washing hands and using separate clean boards for raw and ready-to-eat foods Correct answer.
  3. Storing the lunch next to raw meat in the fridge
  4. Using the same board for raw meat and salad without washing it

Explanation

Cross-contamination occurs when pathogens from raw foods transfer to ready-to-eat foods via hands, boards or utensils. Separate colour-coded boards and hand washing break that transfer route.

Question 20Home Economics

Which of the following is an example of a fixed household expense rather than a variable one?

  1. Weekly grocery spending
  2. Electricity used each month
  3. Fuel for occasional car trips
  4. Monthly rent payment Correct answer.

Explanation

A fixed expense stays the same regardless of usage, and rent is agreed in advance and paid regularly. Electricity, groceries and fuel vary with consumption and are therefore variable expenses.

Question 21Home Economics

Which statement about the role of protein in the diet of adolescents is most accurate?

  1. Protein provides amino acids for growth and repair of body tissues Correct answer.
  2. Protein supplies the main energy reserve stored under the skin
  3. Protein is a mineral needed for strong bones
  4. Protein is needed only by athletes and manual workers

Explanation

Dietary protein is digested into amino acids, which are reassembled into the body's own proteins for growth, tissue repair and enzyme production, a need that is high during adolescent growth spurts. Energy storage under the skin is the role of fat.

Question 22Home Economics

A family wants to lower the saturated fat in their diet without removing fat entirely. Which change is most appropriate?

  1. Replacing butter with olive oil and grilling instead of frying Correct answer.
  2. Removing all fat from the diet
  3. Switching from chicken to fatty lamb
  4. Adding cream to sauces instead of stock

Explanation

Unsaturated plant oils such as olive oil contain less saturated fat than butter, and grilling allows fat to drain away rather than being absorbed as in frying. Some fat is still needed for essential fatty acids and fat-soluble vitamins.

Question 23Home Economics

Which property of a fabric makes it suitable for a child's nightwear that must meet flammability safety requirements?

  1. High flammability with a loose brushed surface
  2. High static electricity generation
  3. Very lightweight open weave with long loose fibres
  4. Flame-resistant treatment or inherently flame-retardant fibres Correct answer.

Explanation

Nightwear safety standards require fabrics that resist ignition or burn slowly, achieved through flame-retardant finishes or inherently flame-retardant fibres. Loose brushed surfaces and open lightweight weaves ignite and burn readily.

Question 24Home Economics

Which of these is the most energy-efficient way to dry a load of washing on a sunny, breezy day?

  1. Draping the washing over a radiator indoors
  2. Using a tumble dryer on a low heat setting
  3. Using a tumble dryer on high heat
  4. Hanging the washing outdoors on a line Correct answer.

Explanation

Line drying uses free solar energy and air movement, so it consumes no electricity at all. Tumble drying and radiator drying both require paid energy, with high heat using the most.

Question 25Home Economics

A pattern envelope states a fabric requirement of 2.5 m for a 115 cm wide fabric. If the chosen fabric is only 90 cm wide, what is the most sensible response?

  1. Buy extra length, as a narrower fabric needs more metres for the same pattern pieces Correct answer.
  2. Assume the pattern pieces can be shrunk to fit
  3. Buy 2.5 m anyway because width does not affect layout
  4. Buy half the stated amount to save money

Explanation

Narrower fabric means fewer pattern pieces fit across the width, so more length is needed to lay them out without overlap. Pattern envelopes list requirements for specific widths for exactly this reason.

Question 26Home Economics

Which nutrient is the main building material for growth and repair of body tissues during adolescence?

  1. Vitamin C
  2. Calcium
  3. Dietary fibre
  4. Protein Correct answer.

Explanation

Protein supplies the amino acids needed to build new tissue, so it is central to growth and to repairing muscles and skin. Calcium and vitamin C support specific body functions but do not provide the structural material for tissue growth in the same way.

Question 27Home Economics

Which statement correctly describes the term 'discretionary income' in a household budget?

  1. The total amount earned before any tax or deductions are taken
  2. The amount owed on credit cards and other borrowing
  3. Money left after essential spending such as rent, food and utilities have been paid Correct answer.
  4. The money set aside each month for savings and investments only

Explanation

Discretionary income is what remains once essential commitments are covered, and it is the part a household can choose how to spend. It is distinct from gross income and from money already committed to savings or debt.

Question 28Home Economics

Which of these is a natural protein fibre obtained from an animal source?

  1. Linen
  2. Viscose
  3. Cotton
  4. Wool Correct answer.

Explanation

Wool is a protein fibre grown from the fleece of sheep, which is why it behaves differently from cellulose fibres when burned or washed. Cotton and linen are plant cellulose fibres, and viscose is manufactured from regenerated wood pulp.

Question 29Home Economics

Which piece of equipment is designed specifically to measure small volumes of liquid such as vanilla essence accurately?

  1. A balance scale
  2. A sieve
  3. A measuring spoon Correct answer.
  4. A measuring jug

Explanation

Measuring spoons are calibrated for small quantities and are used for flavourings and raising agents where accuracy matters. A jug is intended for larger volumes, and a balance scale measures mass rather than volume.

Question 30Home Economics

Which practice best protects a consumer who buys a faulty electrical appliance from a shop?

  1. Paying in cash so that no record of the purchase exists
  2. Keeping the receipt as proof of purchase and requesting a repair or replacement Correct answer.
  3. Discarding the packaging immediately to save storage space
  4. Using the appliance despite the fault until the guarantee period ends

Explanation

Proof of purchase is what allows a consumer to exercise remedies such as repair, replacement or refund when goods are not of satisfactory quality. Without a record the seller may be unable to verify the transaction.

Question 31Home Economics

Which of the following is a source of unsaturated fat rather than saturated fat?

  1. Butter
  2. Olive oil Correct answer.
  3. Lard
  4. Beef dripping

Explanation

Olive oil is rich in monounsaturated fatty acids, which are classed as unsaturated. Butter, lard and beef dripping are animal fats dominated by saturated fatty acids.

Question 32Home Economics

Which safety practice is most important when handling a hot baking tray taken from an oven?

  1. Placing the hot tray directly on a plastic worktop
  2. Using a dry, thick oven glove to protect the hands Correct answer.
  3. Holding the tray with a folded damp tea towel
  4. Carrying the tray close to the body for balance

Explanation

A dry, thick oven glove insulates the hands from heat and prevents steam burns, which can occur when moisture in a cloth heats up. Hot trays should also be set on a heat-resistant surface rather than a plastic worktop.

Question 33Home Economics

Which of these describes the purpose of a seam allowance in dressmaking?

  1. The fold at the lower edge of a garment
  2. The extra fabric beyond the stitching line that allows the seam to be joined and finished Correct answer.
  3. The measurement taken around the widest part of the hips
  4. The strip of fabric used to face a neckline

Explanation

A seam allowance is the margin of fabric left outside the stitching line so the seam can be sewn, pressed and finished without fraying away. It is normally marked on commercial patterns, typically 1.5 cm.

Question 34Home Economics

A household spends €90 per week on food for four people. What is the average food cost per person per day?

  1. €2.25
  2. €3.21 Correct answer.
  3. €6.43
  4. €4.50

Explanation

Divide €90 by four people to get €22.50 per person per week, then divide by seven days, giving about €3.21 per person per day. Rounding the answer to the nearest cent keeps the figure practical.

Question 35Home Economics

Which change to a white sauce recipe would produce a thinner sauce of the same volume?

  1. Reducing the flour while keeping the milk quantity the same Correct answer.
  2. Heating the sauce for a much longer time
  3. Replacing milk with single cream
  4. Increasing the butter and flour in equal amounts

Explanation

Flour is the thickening agent in a roux-based sauce, so less flour in the same volume of milk gives a lower viscosity. Adding equal fat and flour together maintains the thickening ratio, and longer heating only reduces volume through evaporation.

Question 36Home Economics

A recipe states an oven temperature of 180 °C. Which gas mark corresponds most closely to this temperature?

  1. Gas mark 2
  2. Gas mark 6
  3. Gas mark 4 Correct answer.
  4. Gas mark 8

Explanation

Gas mark 4 corresponds to about 180 °C, a common temperature for baking cakes and biscuits. Each gas mark step is roughly 10–15 °C, so higher marks give noticeably hotter ovens.

Question 37Home Economics

Which washing-machine programme is most appropriate for a lightly soiled cotton shirt that must not shrink?

  1. A cotton programme at 90 °C with a high spin
  2. A wool programme at 30 °C with a low spin
  3. A pre-wash cycle at 60 °C followed by a hot rinse
  4. A cotton programme at 40 °C with a moderate spin Correct answer.

Explanation

A 40 °C cotton cycle removes normal soiling while limiting the heat that causes cotton to shrink, and a moderate spin reduces creasing. Very hot cycles risk shrinkage and fading, while a wool cycle does not clean cotton effectively.

Question 38Home Economics

Which property of a fabric is being tested when a small sample is held near a flame to observe whether it melts or chars?

  1. Colour fastness
  2. Dimensional stability
  3. Abrasion resistance
  4. Fibre composition Correct answer.

Explanation

Burning behaviour helps identify fibre type: protein fibres char and smell of burnt hair, cellulose fibres burn like paper, and synthetic fibres melt. Colour fastness, shrinkage and abrasion are tested by entirely different methods.

Question 39Home Economics

A family of five uses 120 litres of hot water per day for showers. Which action would reduce the energy used for water heating most effectively?

  1. Increasing the boiler thermostat setting
  2. Fitting a low-flow shower head and shortening shower times Correct answer.
  3. Using cold water for the final rinse of laundry
  4. Washing dishes by hand instead of using the dishwasher

Explanation

Most of the energy for showers goes into heating water, so reducing the volume used cuts energy demand directly. Raising the thermostat increases energy use, and the other actions affect different appliances.

Question 40Home Economics

Which food-handling practice is most important when defrosting raw chicken for a family meal?

  1. Thawing it in warm water in the sink for several hours
  2. Thawing it on the kitchen worktop at room temperature
  3. Thawing it in a covered container on the bottom shelf of the refrigerator Correct answer.
  4. Refreezing it as soon as the outside feels soft

Explanation

Refrigerator thawing keeps the chicken below 5 °C, which limits bacterial growth, and placing it on the bottom shelf prevents drips contaminating other foods. Warm or room-temperature thawing allows the surface to enter the danger zone while the centre is still frozen.

Question 41Home Economics

Which statement best explains why a garment label advises washing dark denim inside out?

  1. It removes the need for any detergent in the wash
  2. It reduces abrasion on the outer surface and limits colour loss during washing Correct answer.
  3. It allows a higher spin speed to be used safely
  4. It prevents the fabric from absorbing water during the cycle

Explanation

Turning denim inside out protects the visible surface from rubbing against other items and the drum, which reduces fading and pilling. It also limits indigo transfer, but it does not change water absorption or detergent needs.

Question 42Home Economics

A student compares two ready meals with the same energy content per portion. Which additional information is most useful for judging which meal better fits healthy eating guidance?

  1. The amount of saturated fat, salt and fibre per portion Correct answer.
  2. The number of ingredients listed on the label
  3. The price per kilogram of each meal
  4. The total weight of the packaging

Explanation

Healthy eating guidance focuses on the balance of nutrients, especially limiting saturated fat and salt while encouraging fibre. Energy content alone does not show this balance, and price or packaging do not indicate nutritional quality.

Question 43Home Economics

Which design element would most improve a small, dark kitchen without structural changes?

  1. Light-coloured surfaces and good task lighting to reflect light Correct answer.
  2. Dark worktops and heavy patterned wall coverings
  3. Deep-coloured cabinets to create a cosy effect
  4. A single central ceiling light with no task lighting

Explanation

Light surfaces reflect more light and make a small space feel larger, while task lighting illuminates work areas where shadows would otherwise fall. Dark colours absorb light and make confined spaces feel smaller.

Question 44Home Economics

Which of these best describes the term 'planned obsolescence' as it affects household consumers?

  1. Setting a household budget for replacing worn items
  2. Designing products with a limited useful life so that replacement is encouraged Correct answer.
  3. Repairing appliances using genuine spare parts
  4. Buying second-hand goods instead of new ones

Explanation

Planned obsolescence refers to designing goods so they become unfashionable, unrepairable or worn out within a short period, prompting repeat purchase. It raises long-term costs and increases waste, which is why repairability is now a consumer concern.

Question 45Home Economics

A family wants to reduce household food waste. Which strategy addresses the problem at the planning stage rather than after food has been bought?

  1. Writing a weekly meal plan and a shopping list based on what is already in store Correct answer.
  2. Shopping without a list to take advantage of special offers
  3. Buying larger packs because the unit price is lower
  4. Freezing leftovers once they have accumulated at the end of the week

Explanation

Planning meals around existing stock prevents surplus purchases in the first place, which is more effective than dealing with waste afterwards. Buying in bulk without a plan often increases spoilage.

Question 46Home Economics

A pattern requires 2.5 m of fabric at 115 cm width. The chosen fabric is only 90 cm wide. Which approach is most appropriate before buying?

  1. Buy exactly 2.5 m because width does not affect the requirement
  2. Check the pattern's alternative layout for the narrower width, which usually needs more length Correct answer.
  3. Choose a fabric with a larger pattern repeat to reduce the length needed
  4. Buy half the stated length to compensate for the narrower fabric

Explanation

Pattern envelopes give requirements for a stated fabric width because narrower fabric may need extra length to accommodate the same pattern pieces. A larger pattern repeat increases, not reduces, the fabric needed.

Question 47Home Economics

A cake made with the rubbing-in method has a dry, crumbly texture. Which adjustment is most likely to correct the fault?

  1. Adding extra flour to the mixture
  2. Baking at a lower temperature for longer
  3. Increasing the proportion of fat and liquid slightly Correct answer.
  4. Reducing the amount of raising agent

Explanation

A dry crumbly texture in rubbing-in mixtures usually reflects too little fat or liquid to bind the flour particles. Adding more flour would worsen dryness, and reducing raising agent affects rise rather than moisture.

Question 48Home Economics

A family's weekly income is €520. Fixed costs total €300, variable costs €140 and savings €40. Which statement best evaluates their financial position?

  1. They have a surplus of €120 available for discretionary spending
  2. They should reduce savings to zero to cover fixed costs
  3. They are within budget but have little margin for unexpected costs Correct answer.
  4. They are overspending by €40 each week

Explanation

Total commitments of €480 leave €40 unallocated out of €520, so the budget balances but the safety margin is small. A larger contingency would give better protection against unexpected expenses.

Question 49Home Economics

A cotton/polyester blend shirt is labelled 'easy care'. Which explanation best accounts for this claim?

  1. The polyester component reduces creasing and helps the fabric hold its shape after washing Correct answer.
  2. The blend must be dry-cleaned to keep its finish
  3. The cotton component makes the fabric dry faster than pure polyester
  4. The blend cannot absorb moisture at all and so needs no ironing

Explanation

Blending polyester with cotton combines cotton's comfort with polyester's resilience, so the fabric creases less and recovers shape after washing. It still absorbs some moisture and can normally be machine washed.

Question 50Home Economics

A household replaces an old fridge with a more efficient model rated A compared with the old G rating. Which statement best explains the likely long-term financial outcome?

  1. Higher purchase cost is offset over time by lower running costs Correct answer.
  2. Running costs stay the same because energy ratings only affect noise
  3. The saving appears only if the fridge is used less frequently
  4. The purchase cost falls because efficient models are cheaper to make

Explanation

Energy ratings reflect electricity consumption in normal use, so a more efficient appliance costs less to run and the price premium is recovered over its lifetime. The saving depends on usage patterns but does not require using the appliance less.
