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.Rate this question:

As cotton planting expanded, so too did the diversion of water form the two rivers that fed the Aral Sea. And as the sea shrank, the salt concentrations climbed until the fish died. The thriving fisherery that once yielded ______ tons of seafood per year disappeared, as did the jobs on the fishing bots and in the fish processing factories. We are growin cotton in west Texas - a place where cotton can't grow without irrigation. Think about it.

500
- B.
5000
- C.
50000
- D.
500000
Correct Answer
C. 50000Explanation
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.Rate this question:

What country is traditionally the leading wheat importer?
- A.
Canada
- B.
Nepal
- C.
Japan
- D.
China
Correct Answer
C. JapanExplanation
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.Rate this question:

- A.
1000
- B.
10000
- C.
1500
