Q3702. The greenhouse effect refers to:
Explanation
The greenhouse effect is the trapping of heat by atmospheric gases such as carbon dioxide, methane and water vapour, which keeps the Earth warm.
Q3703. Read the following statements regarding the trend of FDI inflows in India post-2000:
I. There has been a steady, long-term increase in cumulative FDI inflows.
II. The services sector (including financial, banking, and insurance) has been a top recipient.
III. Equity inflows constitute the largest component of total FDI.
IV. 100% of the FDI inflow is exclusively directed to the agricultural sector.
V. Repatriation of profits by foreign investors is heavily restricted, deterring FDI.
Which of the statements given above are incorrect?
I. There has been a steady, long-term increase in cumulative FDI inflows.
II. The services sector (including financial, banking, and insurance) has been a top recipient.
III. Equity inflows constitute the largest component of total FDI.
IV. 100% of the FDI inflow is exclusively directed to the agricultural sector.
V. Repatriation of profits by foreign investors is heavily restricted, deterring FDI.
Which of the statements given above are incorrect?
Explanation
Since 2000, India has seen a steady increase in cumulative FDI inflows, with equity being a major component and the services sector as a top recipient. However, it is incorrect to state that 100% of FDI is directed to agriculture, as the sector receives a very small share. Additionally, India generally allows the repatriation of profits by foreign investors, attracting sustained investment.
Q3704. Which of the following greenhouse gases has the highest Global Warming Potential (GWP) per molecule?
Explanation
Different gases vary in their ability to trap heat and their lifespan in the atmosphere. One specific industrial gas is known for being extremely effective at absorbing radiation, making it thousands of times more potent than carbon dioxide on a molecule-for-molecule basis. Because it is very stable and stays in the air for thousands of years, even small amounts contribute significantly to long-term warming.
Q3705. What is the threshold turnover limit for a company to be classified as a ‘Startup’ under the current DPIIT guidelines in India?
Explanation
Under the current guidelines issued by the Department for Promotion of Industry and Internal Trade, a company can be classified as a Startup only if its annual turnover does not exceed one hundred crore rupees for any financial year since its incorporation. This turnover threshold, combined with the ten-year age limit, defines eligibility for various benefits, including tax holidays and innovation support.
Q3706. Consider the following greenhouse gases and their contribution to the natural greenhouse effect:
A. Methane
B. Water vapor
C. Carbon dioxide
Which of the following represents the correct sequence in decreasing order of overall contribution?
A. Methane
B. Water vapor
C. Carbon dioxide
Which of the following represents the correct sequence in decreasing order of overall contribution?
Explanation
Several different substances contribute to the natural warming of the planet. The most significant contributor by far is the gas that forms clouds and humidity. This is followed by a gas released through both natural and human activities like burning fuels. Other potent gases exist in much smaller concentrations but still play a role in the complex interactions that maintain the Earth’s temperature.
Q3707. Read the following statements regarding the MRTP Act, 1969:
I. It aimed to restrict monopolistic trade practices.
II. It was replaced by the Competition Act, 2002.
Which of the statements given above is/are correct?
I. It aimed to restrict monopolistic trade practices.
II. It was replaced by the Competition Act, 2002.
Which of the statements given above is/are correct?
Explanation
The Monopolies and Restrictive Trade Practices Act of 1969 was the primary legislation intended to prevent the concentration of economic power and curb anti-competitive trade practices. As the Indian economy moved toward liberalisation, this act was deemed outdated. Consequently, it was replaced by the Competition Act of 2002. The new law shifted the focus from restricting monopolies to promoting healthy competition.
Q3708. Global warming is best defined as:
Explanation
The long-term increase in the Earth’s average surface temperature is driven primarily by human activities that release heat-trapping gases. Unlike seasonal weather changes or localized heating in cities, this phenomenon affects the entire planet over decades and centuries. It results in widespread changes to weather patterns, rising sea levels, and significant disruptions to ecosystems and human societies across all continents and oceans.
Q3709. Albedo effect is crucial in global warming discussions. What happens when Arctic sea ice melts?
Explanation
The reflectivity of the Earth’s surface plays a critical role in the global climate. Bright surfaces like ice reflect most of the incoming sunlight back into space. When this ice melts and is replaced by dark ocean water, the amount of energy absorbed by the planet increases. This feedback loop accelerates the warming process, leading to even more ice loss and higher temperatures.
Q3710. Under the new composite criteria for MSMEs, if an enterprise has an investment of 8 crore in plant and machinery and an annual turnover of 40 crore, it will be classified as a:
Explanation
According to the 2020 revised MSME classification, an enterprise is categorized as a Small enterprise if its investment in plant and machinery does not exceed ten crore rupees and its annual turnover does not exceed fifty crore rupees. Therefore, an enterprise with eight crore investment and forty crore turnover falls within these specific limits. This ensure businesses are classified based on performance.Answer key for these questions
