SAT II US History Question

<p>I found this question in a book, but don’t really agree with the answer given:</p>

<p>

</p>

<p>I put (A), since as I understand it (E) caused (A), which in turn caused the Great Depression. The answers, however, say that the correct answer is (E). Am I missing something?</p>

<p>thats why you should only use offical tests… both of them are causes but i guess the primary cause was E.</p>
