Select the correct answer from the codes given below. a) Both (A) and (R) are true, but (R) is not the correct explanation of (A). b) (A) is false, but (R) is true. c) Both (A) and (R) are true and (R) is the correct explanation of (A). d) (A) is true, but (R) is false.
Question from UPPSC Prelims 2024
Correct Answer: c) Both (A) and (R) are true and (R) is the correct explanation of (A).
Explanation:
– Assertion (A): The Himalayas are still rising.
This statement is true. The Himalayas are geologically young mountains and are still rising due to tectonic activity.
– Reason (R): The Indian tectonic plate is colliding with the Eurasian plate.
This statement is also true. The Indian plate is moving northward and colliding with the Eurasian plate, causing the crust to buckle and fold, which leads to the uplift of the Himalayas.
– Relationship between (A) and (R): The collision of the Indian and Eurasian plates is the primary reason for the continuous rise of the Himalayas. This tectonic activity causes the mountains to grow in height over time. Therefore, (R) is the correct explanation of (A).
Thus, the correct answer is c) Both (A) and (R) are true and (R) is the correct explanation of (A).

Q. Which one of the following is correctly matched?
a) Ecocline – Biodiversity b) Pycnocline – Sea water density c) Thermocline – Air temperature d) Halocline – Sea water temperature
Question from UPPSC Prelims 2024
Correct Answer: b) Pycnocline – Sea water density
Explanation:
1. Ecocline – Biodiversity
– This is incorrect. An ecocline refers to a gradual transition or gradient between two ecosystems or communities, often marked by changes in environmental conditions (e.g., moisture, temperature). It is not directly related to biodiversity.
2. Pycnocline – Sea water density
– This is correct. A pycnocline is a layer in a body of water where there is a rapid change in water density with depth. This change in density is typically caused by variations in temperature (thermocline) or salinity (halocline).
3. Thermocline – Air temperature
– This is incorrect. A thermocline refers to a layer in a body of water where there is a rapid change in temperature with depth, not air temperature.
4. Halocline – Sea water temperature
– This is incorrect. A halocline refers to a layer in a body of water where there is a rapid change in salinity with depth, not temperature.
Conclusion: The correct match is b) Pycnocline – Sea water density.
Q. Given below are two statements, one is labelled as Assertion (A) and the other as Reason (R).
Assertion (A): Relative humidity decreases with increasing air temperature. Reason (R): Absolute humidity increases with increasing evaporation.
Select the correct answer from the codes given below. a) Both (A) and (R) are true, but (R) is not the correct explanation of (A). b) (A) is false, but (R) is true. c) Both (A) and (R) are true and (R) is the correct explanation of (A). d) (A) is true, but (R) is false.
Question from UPPSC Prelims 2024
Correct Answer: a) Both (A) and (R) are true, but (R) is not the correct explanation of (A).
Explanation:
– Assertion (A): Relative humidity decreases with increasing air temperature.
This statement is true. Relative humidity is the ratio of the actual amount of water vapor in the air to the maximum amount of water vapor the air can hold at a given temperature, expressed as a percentage. As air temperature increases, the air’s capacity to hold water vapor increases, but if the actual amount of water vapor remains constant, the relative humidity decreases.
– Reason (R): Absolute humidity increases with increasing evaporation.
This statement is also true. Absolute humidity refers to the total amount of water vapor present in a given volume of air. When evaporation increases, more water vapor enters the air, leading to an increase in absolute humidity.
– However, (R) is not the correct explanation of (A). The decrease in relative humidity with increasing air temperature is due to the air’s increased capacity to hold water vapor, not directly because of evaporation or changes in absolute humidity.
Biotic succession refers to the natural process by which ecosystems develop and change over time, eventually reaching a stable climax community. The correct sequence of phases in biotic succession is as follows:
1. Migration: This is the initial phase where propagules (seeds, spores, or other reproductive units) of species arrive at a new area through dispersal mechanisms like wind, water, or animals.
2. Ecesis: After migration, the propagules establish themselves in the new environment. This involves germination, growth, and adaptation to the local conditions.
3. Reaction: As the organisms grow and interact with the environment, they modify it (e.g., altering soil composition, light availability, or nutrient cycles). These changes can make the environment more suitable for other species and less suitable for the pioneer species.
4. Stabilisation: This is the final phase where a relatively stable climax community is established. The ecosystem reaches equilibrium, and significant changes in species composition cease.
Thus, the correct sequence is Migration → Ecesis → Reaction → Stabilisation, making option d the correct answer.
Q. Which of the following are the functions of the Election Commissioner of India?
1. Conduct of elections for the posts of the Speaker and the Deputy Speaker of the Lok Sabha and Deputy Chairman of the Rajya Sabha. 2. Conduct of elections of the Municipal Corporations and Municipalities. 3. Deciding on all doubts and disputes arising out of the above elections.
Select the correct answer from the codes given below.
a) 2 and 3 b) 1 and 2 c) 1 and 3 d) None of the above
Question from UPPSC Prelims 2024
Correct Answer: d) None of the above
Explanation:
The Election Commission of India (ECI) is a constitutional body responsible for conducting free and fair elections in India. However, its functions are limited to certain specific elections as per the Constitution and laws.
1. Conduct of elections for the posts of the Speaker and the Deputy Speaker of the Lok Sabha and Deputy Chairman of the Rajya Sabha:
The Election Commission of India does not conduct elections for these posts. These elections are conducted internally by the members of the respective houses (Lok Sabha or Rajya Sabha). Hence, this statement is incorrect.
2. Conduct of elections of the Municipal Corporations and Municipalities:
The Election Commission of India is not responsible for conducting elections to Municipal Corporations and Municipalities. These elections are conducted by the State Election Commissions, which are separate bodies established under Article 243K of the Constitution. Hence, this statement is also incorrect.
3. Deciding on all doubts and disputes arising out of the above elections:
The Election Commission of India does not have the authority to decide disputes related to elections for the Speaker, Deputy Speaker, Deputy Chairman, or Municipal Corporations and Municipalities. Disputes related to parliamentary or state assembly elections are handled by the judiciary (e.g., High Courts). Hence, this statement is also incorrect.
Q. Consider the following statements: An Amendment to the Constitution of India can be initiated by:
1. Lok Sabha 2. Rajya Sabha 3. State Legislatures 4. President of India
Which of the above statements is/are correct?
a) 1, 2 and 3 b) 1 and 2 c) Only 1 d) 2, 3 and 4
Question from UPPSC Prelims 2024
The correct answer is: b) 1 and 2
Explanation:
An amendment to the Constitution of India is governed by Article 368. According to this article, the process of amending the Constitution can only be initiated in Parliament, specifically in either the Lok Sabha or the Rajya Sabha.
1. Lok Sabha: Yes, an amendment can be initiated in the Lok Sabha. This is one of the two houses of Parliament where a bill for constitutional amendment can be introduced.
2. Rajya Sabha: Yes, an amendment can also be initiated in the Rajya Sabha. Like the Lok Sabha, it is part of Parliament and has the authority to introduce and deliberate on constitutional amendment bills.
3. State Legislatures: No, state legislatures cannot initiate an amendment to the Constitution. However, in certain cases (e.g., amendments affecting federal provisions), ratification by at least half of the state legislatures is required after the amendment is passed by Parliament.
4. President of India: No, the President does not have the power to initiate a constitutional amendment. The President’s role is limited to giving assent to the amendment bill after it has been passed by both houses of Parliament as per the procedure laid out in Article 368.
Q. Which of the following is/are stated in the Constitution of India?
1. The President shall not be a member of either of the Houses of the Parliament. 2. The Parliament shall consist of the President and both Houses. Select the correct answer from the codes given below: a) Both 1 and 2 b) Only 2 c) Neither 1 nor 2 d) Only 1
Question from UPPSC Prelims 2024
The correct answer is: a) Both 1 and 2
Explanation:
1. Statement 1: The President shall not be a member of either of the Houses of the Parliament.
– This statement is correct. According to Article 59(1)(a) of the Indian Constitution, the President of India shall not be a member of either House of Parliament or a House of the Legislature of any State. If a person who is a member of any of these bodies is elected as President, they are required to vacate their seat in that body on the date they enter upon their office as President.
2. Statement 2: The Parliament shall consist of the President and both Houses.
– This statement is also correct. As per Article 79 of the Indian Constitution, the Parliament of India consists of the President and the two Houses—namely, the Rajya Sabha (Council of States) and the Lok Sabha (House of the People). The President is an integral part of the Parliament, even though they are not a member of either House.
