Q82. Consider the following statements regarding the Himalayas:
I. They act as a climatic divide for the Indian subcontinent.
II. They are the source of perennial rivers like the Ganga and Brahmaputra.
III. They contain a rich variety of flora and fauna due to diverse altitudinal zones.
IV. They consist strictly of igneous rocks with no sedimentary formations.
V. They prevent the cold continental air masses of Central Asia from entering India.
Which of the above statement(s) is/are correct?
I. They act as a climatic divide for the Indian subcontinent.
II. They are the source of perennial rivers like the Ganga and Brahmaputra.
III. They contain a rich variety of flora and fauna due to diverse altitudinal zones.
IV. They consist strictly of igneous rocks with no sedimentary formations.
V. They prevent the cold continental air masses of Central Asia from entering India.
Which of the above statement(s) is/are correct?
Explanation
The Himalayas function as a major climatic divide, blocking cold Siberian winds and trapping monsoon moisture. They provide a perennial water source for rivers like the Ganga and Brahmaputra. While rich in biodiversity, they are not composed strictly of igneous rocks; they contain significant sedimentary formations. Their height prevents frigid air masses from Central Asia from cooling the Indian subcontinent.
Q83. Consider the following statements concerning national income accounting:
I. GDP at factor cost includes indirect taxes but excludes subsidies.
II. GNP can be lesser than GDP if net factor income from abroad is negative.
III. NNP at market price represents the total value of goods and services produced after allowing for depreciation.
IV. Personal income includes transfer payments received by households.
V. Disposable income is personal income minus personal direct taxes.
Which of the above statement(s) is/are correct?
I. GDP at factor cost includes indirect taxes but excludes subsidies.
II. GNP can be lesser than GDP if net factor income from abroad is negative.
III. NNP at market price represents the total value of goods and services produced after allowing for depreciation.
IV. Personal income includes transfer payments received by households.
V. Disposable income is personal income minus personal direct taxes.
Which of the above statement(s) is/are correct?
Explanation
GNP can be lower than GDP if residents earn less abroad than foreigners earn domestically. NNP at market price accounts for capital depreciation. Personal income includes transfers like pensions, which are not factor incomes. Disposable income is the amount remaining after paying direct taxes. However, GDP at factor cost actually excludes indirect taxes and includes subsidies, making the first statement incorrect.
Q84. Which of the following is defined as the product of the mass of an object and its velocity?
Explanation
Momentum is a vector quantity that represents the quantity of motion an object possesses. It is calculated by multiplying the object’s mass by its velocity. Larger masses or higher speeds result in greater momentum, making the object harder to stop. This concept is fundamental in physics for analyzing collisions and understanding how forces change the motion of objects over specific time intervals.
Q85. What is the most dominant tool type found in the earliest deposits of Singi Talav?
Explanation
The earliest archaeological deposits at Singi Talav are dominated by heavy-duty stone tools belonging to the Acheulian tradition. These include well-crafted handaxes and choppers made primarily from local quartzite. Such artifacts reflect the survival strategies of Lower Palaeolithic hominins who occupied the region. The site provides one of the most well-stratified examples of early human technology in the Indian subcontinent.
Q86. Match the Harappan site in List I with its prominent discovery in List II and select the correct answer.
| Harappan Site | Prominent Discovery |
|---|---|
| A. Chanhudaro | i. Terracotta replica of a plough |
| B. Surkotada | ii. Evidence of bead-making industry |
| C. Banawali | iii. Largest Harappan settlement in India |
| D. Rakhigarhi | iv. Bones of a horse |
Explanation
Specific archaeological finds characterize different Harappan sites. Chanhudaro was a specialized center for bead-making. Surkotada yielded unique evidence of horse remains. Banawali is famous for a high-quality terracotta replica of a plough, providing direct evidence of agricultural tools. Rakhigarhi, located in Haryana, has recently been identified as the largest settlement of this entire civilization within the modern Indian borders.
Q87. Arrange the following events related to the working of the Constituent Assembly in chronological order:
I. Adoption of the National Flag
II. First meeting of the Constituent Assembly
III. Introduction of the Objective Resolution
IV. Adoption of the Objective Resolution
Select the correct order from the options below:
I. Adoption of the National Flag
II. First meeting of the Constituent Assembly
III. Introduction of the Objective Resolution
IV. Adoption of the Objective Resolution
Select the correct order from the options below:
Explanation
The Constituent Assembly first met on December 9, 1946. Jawaharlal Nehru moved the historic Objective Resolution on December 13, 1946, which was subsequently adopted by the assembly on January 22, 1947. Much later, the National Flag of India was officially adopted by the Constituent Assembly on July 22, 1947, shortly before India attained independence from the British rule.
Q88. The formation of the Sierra Nevada mountains in the United States is predominantly an example of which type of mountain building?
Explanation
The Sierra Nevada range in the western United States is a primary example of block mountain formation. It was created through the vertical displacement of massive crustal blocks along fault lines. As the Earth’s crust stretched, certain blocks were uplifted to form high peaks, while others subsided. This process creates the characteristic steep eastern slopes and gradual western inclinations seen today.
Q89. Match List I with List II and select the correct answer using the codes given below:
| National Income Aggregates | Formulas |
|---|---|
| A. GNP at Market Price | i. GDP at Market Price - Depreciation |
| B. NDP at Market Price | ii. NNP at Market Price - Indirect Taxes + Subsidies |
| C. NNP at Factor Cost | iii. GDP at Market Price - Indirect Taxes + Subsidies |
| D. GDP at Factor Cost | iv. GDP at Market Price + Net Factor Income from Abroad |
Explanation
Various national income aggregates are linked through specific adjustments. GNP at market price adds net factor income to GDP. NDP is calculated by removing depreciation from GDP. NNP at factor cost is derived by adjusting market prices for taxes and subsidies. Similarly, GDP at factor cost removes the influence of indirect taxes. These formulas ensure consistency across different accounting frameworks.
Q90. A satellite moving in a uniform circular orbit around the Earth maintains its path primarily due to:
Explanation
A satellite remains in orbit because the Earth’s gravitational pull acts as a centripetal force. This force constantly pulls the satellite toward the center of the planet, changing its direction without altering its speed. This continuous inward acceleration balances the satellite’s tangential velocity, resulting in a stable circular path that prevents it from flying off into space or crashing.Answer key for these questions
