Question

How did tariffs slow down the world trade in the Great Depression.

Is it because one country raises their tariffs to protect their profit, and the other countries vice versa, causing the products to be too expensive for other countries to trade or buy products.

Whoops, a run-on sentence.

Answer 1

Yep -- your answer is right. :-)

It's not a run-on sentence, but would be clearer if you broke it into two sentences.

Answer 2

Alright, thanks :)
