Question 40General Knowledge and Current Affairs

In the context of Madhya Pradesh's geography, which of the following statements about the Vindhya range is correct?

  1. It forms the northern boundary of the Narmada valley and separates the Gangetic plains from the Deccan plateau. Correct answer.

  3. It lies entirely within the Bundelkhand region and is drained mainly by the Betwa and Ken rivers.
  4. It runs along the southern bank of the Narmada and merges into the Satpura range near Amarkantak.

Explanation

The Vindhya range runs roughly east-west across central India, lying north of the Narmada valley.

In Madhya Pradesh the range is prominent around districts such as Rewa, Satna and Vidisha.

Question 41General Science

A constable in Bhopal notices that a sealed packet of chips has puffed up during a long road journey in summer. Which property of gases best explains this observation?

  1. Gases have a fixed volume but no fixed shape
  2. Gases have very strong intermolecular attraction
  3. Gases diffuse only when heated above 100 °C
  4. Gases expand to fill the whole container and exert pressure on its walls Correct answer.

Explanation

Gas particles move randomly at high speed and spread throughout the available space, striking the walls of the container. On a hot journey the trapped air inside the packet gains kinetic energy, hits the sealed walls harder and more often, and the pressure makes the flexible packet bulge. This is a direct consequence of gases having neither fixed shape nor fixed volume.

Question 42General Science

During a police recruitment medical test, a candidate's haemoglobin is found to be low. Which mineral deficiency is most directly linked to this finding?

  1. Iodine
  2. Iron Correct answer.
  3. Calcium
  4. Potassium

Explanation

Haemoglobin is an iron-containing pigment in red blood cells, and iron is the mineral needed for its synthesis. A shortfall of dietary iron therefore lowers haemoglobin and produces anaemia. Iodine relates to thyroid hormones, calcium to bones and clotting, and potassium to nerve and muscle function.

Question 43General Science

A traffic constable standing on a road hears the siren of an approaching ambulance becoming higher in pitch. Which wave property changes for the constable?

  1. The speed of sound in air increases
  2. The wavelength of the sound in air increases
  3. The frequency of the sound received increases Correct answer.
  4. The amplitude of the sound wave increases

Explanation

This is the Doppler effect: when the source moves towards a stationary listener, successive wavefronts are compressed, so more waves reach the ear each second. The received frequency rises and the listener perceives a higher pitch. The speed of sound in air depends on the medium and temperature, not on the motion of the source.

Question 44General Science

In a forensic test, a drop of the suspect's blood is treated with a reagent and a brownish-black colour appears. Which food-derived substance does this test indicate?

  1. Starch
  2. Fat
  3. Protein
  4. Iodine Correct answer.

Explanation

Iodine solution gives a blue-black or brownish-black colour with starch, and the same reaction is used to detect starch in biological samples. The test identifies the starch present, not the iodine itself, which is only the reagent. Protein is detected by the copper sulphate and caustic soda test, and fat by the translucent spot test.

Question 45General Science

A police jeep of mass 1200 kg accelerates uniformly from rest to 20 m/s in 10 s. What is the magnitude of the net force acting on it?

  1. 24000 N
  2. 240 N
  3. 2400 N Correct answer.
  4. 1200 N

Explanation

Acceleration equals change in velocity divided by time, that is 20 m/s ÷ 10 s = 2 m/s². Newton's second law then gives force = mass × acceleration = 1200 kg × 2 m/s² = 2400 N. The calculation uses net force and uniform acceleration, so no other force term is needed.

Question 46General Science

Which part of the human eye changes its curvature to focus objects at different distances?

  1. Cornea
  2. Iris
  3. Retina
  4. Crystalline lens Correct answer.

Explanation

The crystalline lens is held by ciliary muscles, which contract and relax to alter the lens curvature and hence its focal length. This adjustment, called accommodation, allows the eye to focus on near and distant objects. The cornea provides most of the fixed refraction, the retina receives the image, and the iris controls the pupil size.

Question 47General Science

A wire of resistance 12 Ω is cut into three equal parts and all three parts are joined in parallel. What is the equivalent resistance of the combination?

  1. 1.33 Ω Correct answer.
  2. 36 Ω
  3. 4 Ω
  4. 12 Ω

Explanation

Each third of the wire has resistance 12 ÷ 3 = 4 Ω. Three 4 Ω resistors in parallel give 1/R = 1/4 + 1/4 + 1/4 = 3/4, so R = 4/3 ≈ 1.33 Ω. Parallel combination always gives a value smaller than the smallest individual resistance.

Question 48General Science

A constable records that a sample of river water turns red litmus paper blue. Which type of substance is present in the sample?

  1. A base Correct answer.
  2. An acid
  3. A metal
  4. A neutral salt

Explanation

Bases turn red litmus blue, while acids turn blue litmus red. The observed colour change therefore indicates that the sample is basic. Neutral salts and pure metals do not produce this litmus change.

Question 49General Science

Which gas is released when dilute hydrochloric acid is poured over zinc granules in a school laboratory demonstration?

  1. Hydrogen Correct answer.
  2. Carbon dioxide
  3. Chlorine
  4. Oxygen

Explanation

Zinc is a reactive metal that displaces hydrogen from dilute acids, forming zinc chloride and releasing hydrogen gas. The gas burns with a pop sound when a burning splint is brought near it. Oxygen, carbon dioxide and chlorine are not produced in this reaction.

Question 50General Science

A person's blood group is found to be AB. Which statement about this blood group is correct?

  1. The blood has neither A nor B antigens and both antibodies in plasma
  2. The blood has both A and B antigens on red cells and no anti-A or anti-B antibodies in plasma Correct answer.
  3. The blood has only A antigen and anti-B antibodies
  4. The blood has only B antigen and anti-A antibodies

Explanation

In the ABO system, AB individuals carry both A and B antigens on their red blood cells. Because these antigens are recognised as self, the plasma contains neither anti-A nor anti-B antibodies, which is why AB is called the universal recipient. Group O shows the opposite pattern, with no antigens and both antibodies.
