5 我在A 和 C之间犹豫了半天，A可能的问题是 a circumstance ， C可能的问题我觉得是which
和it的指代，最后我决定选A。如果which是指代monkfish那后面的its又是指代什么的 .
所以我仍然的认为应该选A

39 偶觉得B没有错误，species是单复同形的，而且和clones也很好的对应。
偶觉得members对应不如B好
为啥选E呢？

31. Because they can reproduce several times each year and produce large numbers of offspring, many insect species can generally adapt quickly to changes in their environment.
A) Because they can reproduce several times each year and produce large numbers of offspring, many insect species
B) Because of many insect species’ ability of reproducing several times a year, along with producing large number of offspring, thus they
C) Because they can reproduce yearly several times, along with producing offspring in large numbers, so many insect species
D) Due to their capability to reproduce several times yearly and to produce large numbers of offspring, many insect species
E) Due to their ability of reproducing several times yearly and to produce offspring of large numbers, many insect species

31为什么会选E，due to 是介词，后面的to produce offspring of large numbers部分是
隶属于ability的， 我觉得这个结构很奇怪ability of ... and to ...，另外 produce offspring
of large numbers， 我觉得没有 produce large numbers of offspring好，我觉得重点
应该落在large numbers上，而不是offspring上。

另外A中的each year和yearly，我刚刚查了一下郎文和韦氏，确认了一下

each: being one of two or more distinct individuals having a similar relation and often
constituting an aggregate (韦氏)
each is used for any number of people or things taken separetely (郎文)

所以或者可以理解为用在这里不好

A还为什么错，because/due to; can的重复？

请教！
