Answer 2

书是可数名词，there be结构中的 be用复数 were

正确的是

There were not many books in it.

Answer 3

这个地方应该填any books。因为这个是在否定句，在not后面。

any/some用法如下：
some和any 既可以修饰可数名词又可以修饰不可数名词,some常用在肯定句中,而any则常用在否定和疑问句中.因此 some和any 的用法主要是考虑用在肯定句、疑问句还是否定句中,与名词的可数与否无关。
综合上面的分析，空格中应该用any books。

Answer 4

there was not many/a lot of books in it.

Answer 5

填any book
