    The capital markets typically include financial markets where long-term debt (bonds) or equity-backed securities (stocks) are bought and sold. Let’s analyze the given options:

    1. Government Bond Market: This is part of the capital market as it deals with long-term securities (bonds).
    2. Call Money Market: This is part of the money market, not the capital market, as it deals with very short-term funds (usually overnight loans).
    3. Treasury Bill Markets: Treasury bills are short-term debt instruments, which are part of the money market, not the capital market.
    4. Stock Market: This is part of the capital market as it involves trading equity-backed securities.

    Therefore, only two of the above markets, the Government Bond Market and the Stock Market, are included in capital markets. The correct answer is Only two.

    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.

    Hydrofluorocarbons (HFCs) are synthetic chemicals widely employed in industries, mainly for refrigeration and cooling purposes. These man-made compounds were introduced as alternatives to ozone-depleting substances that are being phased out under the Montreal Protocol. HFCs are specifically designed for applications in refrigeration, air-conditioning, aerosol propellants, and insulating foams, with additional, smaller roles in fire protection and as solvents. Unlike some other compounds, HFCs lack lubricating properties. Therefore, the correct option is Only three.

    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.

    Scarcity is a fundamental concept in economics that arises because resources are limited while human wants are virtually unlimited. This imbalance forces individuals, businesses, and governments to make choices about how to allocate resources efficiently. Scarcity drives the need for trade-offs and prioritization, which are central themes in economics. Economists study how these decisions are made and the resulting impact on production, distribution, and consumption.

    The correct answer is: Hunting and gathering.

    Explanation:

    The Mesolithic period (Middle Stone Age) is characterized by a transitional phase between the Paleolithic (Old Stone Age) and Neolithic (New Stone Age). During this period, human societies primarily relied on hunting, gathering, and fishing as their main economic activities. However, they also began experimenting with early forms of domestication and primitive agriculture.

    Key Features of the Mesolithic Economy:

    1. Hunting and Gathering:
      • The primary source of food was hunting animals and gathering wild plants, nuts, and fruits.
      • Tools like microliths (small, sharp stone tools) were used to make weapons like arrows and harpoons for more efficient hunting.
    2. Fishing:
      • Fishing became an important activity, with the development of tools like fish hooks and nets.
    3. Early Domestication:
      • While the Mesolithic economy was predominantly based on hunting and gathering, some evidence suggests the beginning of animal domestication (e.g., dogs) and rudimentary agriculture.
    4. Seasonal Settlements:
      • People began living in semi-permanent shelters as they exploited resources in specific areas.

    Why Other Options Are Incorrect:

    1. Agriculture:
      • Agriculture became the dominant economic activity in the Neolithic period, not the Mesolithic period.
    2. Pastoralism:
      • While early domestication began in the Mesolithic period, full-fledged pastoralism emerged later during the Neolithic period.
    3. Industry:
      • The concept of industry is associated with much later periods, such as the Industrial Revolution.

    Thus, the economy of the Mesolithic period was primarily based on hunting and gathering.

    The meaning of Crop rotation is the practice of growing different crops in a specific order on the same land over multiple seasons. The goal of crop rotation is to maintain the soil’s productivity by preventing it from being used for only one set of nutrients.
    Crop rotation can have many benefits, including:
    Soil health: Improves soil structure, fertility, and organic matter
    Pest and disease control: Breaks the life cycle of pests and diseases, reducing the need for chemical pesticides
    Weed growth: Reduces weed growth
    Crop yield: Increases crop yield
    Labor efficiency: Distributes labor more evenly throughout the seasons
    A simple rotation might involve two or three crops, while a complex rotation might include a dozen or more. For example, a farmer might plant beans after harvesting corn because corn uses a lot of nitrogen and beans return nitrogen to the soil.

    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

    The correct answer is: From hunting-gathering to settled agriculture.

    Explanation:

    The Neolithic Revolution marks a significant transformation in human history when societies shifted from a nomadic, hunting-gathering lifestyle to one of settled agriculture and domestication of animals. This transition occurred around 10,000 BCE in different parts of the world.

    Key Features of the Neolithic Revolution:

    1. Agriculture:
      • Cultivation of crops like wheat, barley, rice, and maize began.
      • It allowed for food surplus, leading to population growth.
    2. Domestication of Animals:
      • Animals like sheep, goats, cattle, and pigs were domesticated for food, labor, and other resources.
    3. Sedentary Lifestyle:
      • People started living in permanent settlements, giving rise to early villages and communities.
    4. Stone Tools:
      • Tools became more specialized, such as sickles and grinding stones for farming activities. However, metal tools came much later.
    5. Social Organization:
      • With surplus food, societies began to develop divisions of labor and complex social structures.

    Why the Other Options Are Incorrect:

    1. From stone tools to metal tools:
      • This transition occurred later, during the Chalcolithic and Bronze Ages.
    2. From nomadic life to urbanization:
      • Urbanization happened much later, during the Bronze Age, after the development of cities like those in Mesopotamia and the Indus Valley.
    3. From nomadic life to urbanization (duplicate option):
      • Urbanization was not a direct feature of the Neolithic Revolution.

    Thus, the Neolithic Revolution is best characterized by the transition from hunting-gathering to settled agriculture.

    Let’s examine each asset:

    1. Brand recognition: This is considered an intangible asset. It represents the value associated with a brand’s reputation and customer awareness, but it has no physical presence.
    2. Inventory: This is not considered an intangible asset. Inventory refers to the goods a company holds for sale and is a physical, tangible asset.
    3. Intellectual property: This is an intangible asset. Intellectual property includes patents, copyrights, trademarks, etc., which are valuable but non-physical in nature.
    4. Mailing list of clients: This is also considered an intangible asset. While it may exist in a physical form (as a database), the value lies in the relationships and potential business it can generate, making it intangible.

    Thus, three of the four are intangible investments. The correct answer is Only three.
