Question

When Egypt made cotton its biggest crop, what major risk did it take?

making farming more important than industrialization
growing a crop in an unsuitable climate
choosing a crop for which there was little demand
depending on a crop whose price might go down

Answer 1

Depending on a crop whose price might go down.

Reason: Egypt became heavily dependent on exported cotton, making its economy vulnerable to fluctuations in global cotton prices and demand (a single-crop/monoculture risk).
