Why might residents in a desert community rely on imported food rather than growing all crops locally?

• A. Some crops cannot be grown locally in the desert due to climate
• B. Local farms produce everything needed
• C. Deserts have plenty of water for farming
• D. Desert soils are always fertile

Answer: (A)

The main idea is that climate limits what can be grown locally. In a desert, extremely hot temperatures, very low rainfall, and scarce water make many crops hard to grow or require intensive irrigation. Because of these conditions, only a narrow range of crops can be produced locally, so residents rely on imported foods to obtain a wider variety. Desert soils can also be poor at retaining water and may be salty, which adds another barrier to farming on a large scale.

This helps explain why some crops simply can’t be cultivated locally under desert conditions, even if other crops could be grown with enough water or irrigation. That’s why importing food is common: it compensates for what the local climate and resources can’t sustain.
