    Lake Chad has shrunk by 96% in the past 40 years. This means that the lake has lost a significant amount of its original size, with only a small fraction remaining. The drastic reduction in size is likely due to a combination of factors such as climate change, increased water usage for agriculture, and population growth in the surrounding areas. The shrinking of Lake Chad has had severe consequences for the local communities and ecosystems that depend on the lake for their livelihoods and survival.

    • 1000

    • 10000

    • 1500

    Correct Answer
    A. 1000
    Explanation
    When the water supply drops below 1000 cubic meters per person, people face scarcity. This means that there is not enough water available for each individual to meet their basic needs. Scarcity of water can lead to various problems such as inadequate sanitation, limited access to clean drinking water, and difficulties in agriculture and food production. It is important to ensure a sufficient water supply to prevent these issues and maintain the well-being of the population.

    • 50000

    • 500000

    Correct Answer
    A. 50000
    Explanation
    The given passage states that as cotton planting expanded, water from the rivers that fed the Aral Sea was diverted, causing the sea to shrink and salt concentrations to rise. This led to the death of fish and the decline of the fishery industry. Therefore, the correct answer of 50000 tons is a reasonable estimate for the amount of seafood that was once yielded per year.

    What country is traditionally the leading wheat importer?

    • Canada

    • Nepal

    • Japan

    • China

    Correct Answer
    A. Japan
    Explanation
    Japan is traditionally the leading wheat importer because it has a high demand for wheat due to its large population and limited agricultural land. Japan relies heavily on wheat imports to meet its domestic demand for wheat-based products such as bread, noodles, and pastries. The country's traditional cuisine also includes a variety of wheat-based dishes, further driving the need for wheat imports. Additionally, Japan's climate and topography are not suitable for large-scale wheat cultivation, making it dependent on imports to fulfill its wheat requirements.
