how have geographic conditions most impacted South Asia's economic activities

Question

1)Lack of arable land has made farming impossible

2) Difficult terrain has led people to rely on forest resources

3)Inadequate rainfall has encouraged people to develop irrigation methods

4)Seasonal climate changes create unstable working conditions

I think it's b.

Answer 1

Nope. What does your text say?

Answer 2

It says the land is dry and rocky. Would it be a?

Answer 3

It was b. :[

Answer 4

It depends on what is considered "South Asia". Much of the land is dry and rocky in southwest Asia, what we sometimes call the Middle East, and some of the "-stan" nations. Other areas have monsoons, such as the Indian subcontinent and Southeast Asia, so are not dry at all. Farming is not impossible in any of those areas that are near rivers which are used for irrigation or rely on the monsoons for moisture.

So, I think both of your guesses are wrong. Do not post this question again.
