答案：A

这后面一句话里面的of what 与前面一句的in what 有何不同啊，后面这个of what感觉不是定语从句，但到底是什么语法结构呢？

25. Visibly only through large telescopes, Pluto has a yellowish color, which indicates that there is very little atmosphere.

答案：A

不过这句话怎么觉得visibly没错啊？副词修饰介词短语在前面做状语啊，该了形容词算什么结构呢？

39. Humans do not constitute the only species endowed with intelligence: the higher animals also have considerably problem-solving abilities.

答案：D

这句话里面的considerably不可以是副词修饰have吗？

第一个in what是考定语从句的使用，是考的what跟which的混淆。

第二个what是of 结构后面的名词性从句做宾语，what would later become the state of Virginia，只能用有实义的what而不能用其他的which，where 等。

不是，语义上理解，是修饰后面的ability。
