    Here’s an explanation for each statement:

    1. Some microorganisms can grow in environments with temperatures above the boiling point of water: This is correct. Certain microorganisms, known as thermophiles or hyperthermophiles, can thrive in extremely hot environments, such as hydrothermal vents, where temperatures exceed 100°C (the boiling point of water at sea level).
    2. Some microorganisms can grow in environments with temperatures below the freezing point of water: This is correct. Psychrophiles are microorganisms that can grow in extremely cold environments, including those with temperatures below 0°C, such as in polar regions or glaciers.
    3. Some microorganisms can grow in a highly acidic environment with a pH below 3: This is correct. Acidophiles are microorganisms that can thrive in highly acidic conditions, including environments with pH levels as low as 1, such as in acid mine drainage or acidic hot springs.

    Thus, all three statements are correct. The correct answer is All three.

    Indonesia has rapidly ascended to the position of the world’s second-largest cobalt producer, leading to a substantial decline in the price of this essential battery metal and intensifying Western concerns over China’s stronghold in the electric vehicle supply chain. Last year, the Southeast Asian nation produced 9,500 tonnes of cobalt, representing 5 percent of the global supply, a significant leap from its negligible production levels before 2021. Nevertheless, Indonesia still trails significantly behind the Democratic Republic of Congo, the top global supplier, which commands a dominant 73 percent share of the market. So, the correct answer is: The Democratic Republic of the Congo

    Correct Answer: Infrared waves are largely absorbed by water vapor that is concentrated in the lower atmosphere.

    Explanation:

    1. “The total amount of insolation received at the equator is roughly about 10 times that received at the poles.”
      Incorrect.
      While there is a significant difference in insolation between the equator and the poles due to the angle of incidence of solar radiation, it is not as extreme as 10 times. The actual difference is much smaller, generally ranging from 2 to 3 times.
    2. “Infrared rays constitute roughly two-thirds of insolation.”
      Incorrect.
      Infrared rays are part of the electromagnetic spectrum, but they only constitute a small portion of the incoming solar radiation (insolation). The majority of insolation consists of visible light and ultraviolet radiation.
    3. “Infrared waves are largely absorbed by water vapor that is concentrated in the lower atmosphere.”
      Correct.
      Infrared waves, which are long-wavelength radiation, are absorbed by greenhouse gases such as water vapor, carbon dioxide, and methane. Water vapor, concentrated in the lower atmosphere (troposphere), plays a major role in absorbing and trapping infrared radiation, contributing to the greenhouse effect.
    4. “Infrared waves are a part of the visible spectrum of electromagnetic waves of solar radiation.”
      Incorrect.
      Infrared waves are not part of the visible spectrum. The visible spectrum includes wavelengths between 400-700 nanometers, whereas infrared waves are longer than this range and are not visible to the human eye.

    The Congo Basin is a large, tropical rainforest region in central Africa that spans across several countries. The main countries that make up the Congo Basin are:

    1. Democratic Republic of the Congo (DRC) – It holds the largest portion of the Congo Basin and is home to a significant part of the rainforest.
    2. Republic of the Congo – Also known as Congo-Brazzaville, this country has a substantial portion of the Congo rainforest.
    3. Central African Republic – Located to the north of the Congo Basin, it contains part of the rainforest region.
    4. Gabon – Although it has a smaller share, Gabon has a well-preserved part of the Congo Basin rainforest.
    5. Cameroon – The southern part of Cameroon is part of the Congo Basin.
    6. Equatorial Guinea – The mainland region of Equatorial Guinea (Río Muni) is included in the Congo Basin.

    These countries collectively make up the Congo Basin region, which is the second-largest tropical rainforest in the world, after the Amazon. It is known for its rich biodiversity, complex ecosystems, and significant role in regulating the Earth’s climate. So, Cameroon is the correct answer.

    Correct Answer: Statement-I is incorrect but Statement-II is correct

    Explanation:

    1. Statement-I: “The soil in tropical rain forests is rich in nutrients.”
      Incorrect.
      The soil in tropical rainforests is typically poor in nutrients. This is because heavy rainfall causes leaching, washing away nutrients from the topsoil. Most of the nutrients in tropical rainforests are found in the biomass (plants and trees) rather than in the soil.
    2. Statement-II: “The high temperature and moisture of tropical rain forests cause dead organic matter in the soil to decompose quickly.”
      Correct.
      Tropical rainforests experience warm and humid conditions, which accelerate the decomposition of organic matter. This rapid decomposition ensures that nutrients are quickly absorbed by plants, leaving little in the soil.

    Conclusion:

    The soil in tropical rainforests is nutrient-poor, despite the rapid decomposition of organic matter due to the high temperature and moisture.
    Thus, Statement-I is incorrect, but Statement-II is correct.

    Let’s evaluate the above statements:

    1. Amarkantak Hill:
      • Recognized as a significant natural heritage site.
      • Serves as the junction of the Vindhya and Satpura Ranges.
      • Therefore, statement 1 is INCORRECT.
    2. Biligirirangan Hills:
      • Located in the southeastern region of Karnataka.
      • The Satpura Range, in contrast, begins in eastern Gujarat and extends eastward, bordering Maharashtra and Madhya Pradesh, ultimately reaching Chhattisgarh.
      • Hence, statement 2 is INCORRECT.
    3. Seshachalam Hills:
      • Part of the Eastern Ghats in southern Andhra Pradesh.
      • The Western Ghats, however, span across several states including Kerala, Tamil Nadu, Karnataka, Goa, Maharashtra, and Gujarat.
      • Thus, statement 3 is INCORRECT.

    Therefore, the correct answer is None.

    Infrastructure Investment Trusts (InVITs) gather funds from investors, which are subsequently directed into infrastructure projects. As pooled investment vehicles, they function similarly to mutual funds. However, while mutual funds predominantly invest in stocks and bonds, InVITs focus on infrastructure-related ventures. The returns generated by InVITs are distributed to investors through four primary methods: interest on capital, dividends, rental income, and repayment of capital. Previously, interest, dividends, and rental income earned by unit holders were taxable, but repayment of capital was exempt from tax. However, the Finance Act of 2023 introduced a provision to tax certain portions of capital repayment in specific cases, making Statement 1 incorrect. Additionally, the Finance Act of 2021 amended the SARFAESI Act of 2002 to recognize pooled investment vehicles, including REITs and InVITs, as borrowers under the Act, making Statement 2 correct.

    Therefore, the correct answer is Statement-I is incorrect but Statement-II is correct.

    Correct Answer: All three

    Explanation:

    1. Gold mining activity is a source of mercury pollution in the world:
      Correct. Artisanal and small-scale gold mining (ASGM) is one of the largest global sources of mercury emissions. Mercury is used in the extraction process to amalgamate gold, releasing significant amounts of mercury into the environment.
    2. Coal-based thermal power plants cause mercury pollution:
      Correct. Coal contains trace amounts of mercury. When coal is burned in thermal power plants, mercury is released into the atmosphere as a pollutant.
    3. There is no known safe level of exposure to mercury:
      Correct. Mercury is highly toxic, and even low levels of exposure can lead to serious health effects. The World Health Organization (WHO) states that there is no safe threshold for mercury exposure, particularly for vulnerable groups such as pregnant women and children.

    Hence, all three statements are correct.
