Q7GeographyClimatology and Atmospheric CirculationPYQ 2005

Assertion (A): Wind patterns are clockwise in the northern hemisphere and anticlockwise in the southern hemisphere. Reason (R): The directions of wind patterns in the northern and the southern hemisphere are governed by the Coriolis effect.

  • ABoth (A) and (R) are individually true and R is the correct explanation of A
  • BBoth (A) and (R) are individually true and R is not the correct explanation of A
  • CA is true but R is false
  • DA is false but R is trueCorrect

Explanation

Correct. The assertion is false because it oversimplifies — in the Northern Hemisphere, winds spiral anticlockwise around cyclones but clockwise around anticyclones. The reverse applies in the Southern Hemisphere. The Coriolis effect (Reason) is indeed the governing factor.

Why the other options are incorrect
Option A

The assertion is incorrect. Wind patterns around low-pressure systems (cyclones) are anticlockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

Option B

The assertion overgeneralises. Whether winds are clockwise or anticlockwise depends on whether the system is a cyclone or anticyclone.

Q12Polity & GovernancePhilosophy of the ConstitutionPYQ 2005

Consider the following statements: 1.

  • B1 and 3
  • C3 only
  • D1 onlyCorrect

Explanation

Correct. Articles 371A to 371I were indeed inserted to address region-specific demands of the listed States. Statement 2 is wrong because the US has dual citizenship (federal and State), and Statement 3 is wrong because a naturalised citizen can be deprived of citizenship under the Citizenship Act.

Why the other options are incorrect

Incorrect. Statements 2 and 3 are false. The United States has dual citizenship at the federal and State level, unlike India which has single citizenship. A naturalised citizen can be deprived of citizenship under the Citizenship Act 1955.

Statement 3 is false. Under Section 10 of the Citizenship Act 1955, a naturalised citizen may be deprived of citizenship on grounds such as fraud in obtaining it, disloyalty, or trading with the enemy during war.

Option C

Statement 3 is false. The Citizenship Act 1955 provides specific grounds on which a naturalised citizen can be deprived of Indian citizenship.

  • BPower Plant at Jamnagar (Gujarat) — Essar Power
  • CNabinagar Power Plant (Bihar) — Indian Railways
  • DKayamkulam Power Plant (Kerala) — National Thermal Power Corporation

Why the other options are incorrect
Option B

Essar Power did operate a power plant at Jamnagar in Gujarat, so this pairing is correct.

Option C

The Nabinagar thermal power project in Bihar was indeed associated with Indian Railways (developed by Bhartiya Rail Bijlee Company Ltd, a joint venture involving Indian Railways).

The Kayamkulam (Rajiv Gandhi) Thermal Power Station in Kerala is operated by NTPC, so this pairing is correct.

Q15History & CultureGandhian Era (1919-1939)PYQ 2005

  • A1 and 2
  • B2 and 3
  • C1 and 3
  • D1, 2 and 3Correct

Explanation

Why the other options are incorrect
Option A

Statements 1 and 2 are correct, but statement 3 is also correct. The 1935 Act did provide for an All India Federation.

Option B

Statements 2 and 3 are correct, but statement 1 is also correct. Provincial autonomy was a key feature replacing the earlier dyarchy system.

Option C

Statements 1 and 3 are correct, but statement 2 is also correct. The Federal Court was established under this Act.

Q16GeographyEarth Structure and GeomorphologyPYQ 2005

Assertion (A): The same face of the Moon is always presented to the Earth. Reason (R): The Moon rotates about its own axis in 23 days which is about the same time that it takes to orbit the Earth.

  • ABoth A and R are true, and R is the correct explanation of A
  • BBoth A and R are true, but R is not the correct explanation of A
  • CA is true, but R is falseCorrect
  • DA is false, but R is true

Explanation

Correct. The same face of the Moon is always visible from Earth (tidally locked). However, the reason is false because the Moon's rotation period is about 27.3 days (not 23 days), which equals its orbital period around Earth.

Why the other options are incorrect
Option A

R contains a factual error about the rotation period of the Moon, so it cannot be a correct explanation.

Option B

R is false because the Moon's rotation period is approximately 27.3 days, not 23 days.

Option D

A is true. Tidal locking ensures the Moon always shows the same face to Earth. The reason incorrectly states the rotation period as 23 days.

Why the other options are incorrect
Option A

Kochi does receive the most rainfall, but Delhi receives less than Patna, making the last two positions incorrect.

Option B

Kochi receives more annual rainfall than Kolkata, so Kolkata cannot be first in a decreasing order.

Option D

Kochi receives more rainfall than Kolkata, and Delhi receives less than Patna, making this sequence incorrect.

  • DNeither 1 nor 2

Option A

Incorrect. Lord Wavell, not Lord Mountbatten, was the Viceroy when the Simla Conference took place in 1945. Mountbatten arrived in India only in March 1947.

Why the other options are incorrect
Option A

Africa (20.4%) has a larger land area than North America (16.5%), so Africa should come first in the decreasing order.

Reason (R): The__(__(__(__(__(__(__(__(__(__(pancreatic__(__(__(__(__(__(juice contains__(__(__(__(__(__(__(__(__(__(__(__(__(__(__(__(__(__(__(__(the__(__(__(__(__(__(__(__(__(__(__(__(__(__(__(__(__(__(__(proteolytic__(__(__(__(__(__(__(__(enzyme__(__(__(__(__(__(__(trypsinogen which is released into the small intestine. Select the correct answer.

  • ABoth A and R are individually true and R is the correct explanation of A
  • BBoth A and R are individually true but R is not the correct explanation of ACorrect
  • CA is true but R is false
  • DA is false but R is true

Explanation

Correct. Proteins are indeed broken down into amino acids for absorption (A is true). Pancreatic juice does contain trypsinogen (R is true). However, R does not fully explain A because protein digestion involves multiple enzymes including pepsin, trypsin, chymotrypsin and peptidases.

Why the other options are incorrect
Option A

While both statements are true, trypsinogen alone does not explain the complete digestion and absorption of proteins as amino acids.

Option C

R is factually correct; trypsinogen is indeed present in pancreatic juice.

Option D

A is also true; dietary proteins are digested to amino acids before absorption.
