13. The medieval scholar made almost no attempt to investigate the anatomy of plants, their mechanisms of growth, nor the ways where each was related to the other.

(A) nor the ways where each was related to the other

(B) nor how each was related to some other

(C) or the way where one is related to the next

(D) or the ways in which they are related to one another

(E) or the ways that each related to some other

答案选择的D, 但是文中made是过去式, they are related中用are时态是否不对呢?

另外no attempt也需要用or来连接,而不是and吗?

谢谢!!

1# 表示否定的 not A ,B , or C 结构中 最后一个连词要用 or ，而不是and.

2# 这里the ways in which they are related to one another 我认为它表示的是一般事实，用一般现在时是正确的。
