17。Folktale adptations from oral tradition to other forms of expression,notably

print and film, have made for more than three centuries.

答案给的是D,请给解释一下好吗？

31. Over the entirely surface of earth, there is not a cubic inch of air nor an ounce of soil in which water is not present.

A,C我觉得都有问题，这里的答案是A。 nor用的正确请问是什么原因

40， the planet Venus is comparing with Earth in terms of size,mass, and density, but has a thick carbon dioxide atmosphere, a slow roation , and no moon.

我选择D,我觉得but 后边是一个句子，应该有主语，答案是A,请给解释。
