Answer 1

1. One wrong idea we must guard against is that art history is not a development from primitive begins in the past to final perfection in our own period.

注：这是一个较复杂的从句结构，剖析后，可以看出主句是：One wrong idea is (that) ... we must guard against 修饰one wrong idea

翻译：我们必须防止这样的错误观念：美术史并不是从过去的原始开端直到现在的完美状态的发展过程。

2. The American dream is most plausible during the periods of productivity and wealth generated by American capitalism

注：主句是the American dream is...
状语during the periods of productivity and wealth修饰， 而 generated by...又修饰the periods of productivity and wealth

翻译：在生产力和财富受美国资本主义驱动的时期，美国梦看起来是最不真实的。
