[求助]请教两个句法

dreadpower

大全102.Although the term “psychopath” is popularly applied to an especially brutal criminal, in psychology it is someone who is apparently incapable of feeling compassion or the pangs of conscience.
(A) it is someone who is
(B) it is a person
(C) they are people who are
(D) it refers to someone who is
(E) it is in reference to people
    答案是D，没有问题
    这里的 someone 或者person、 people 后的who is（are)是不是不能省略？感觉上省略不对

97.Although the coordination of monetary policy can help facilitate the orderly financing of existing imbalances, it is unlikely that its effect on their size is significant in the absence of an appropriate fiscal adjustment.
(A) it is unlikely that its effect on their size is significant
(B) it is unlikely that the size of their effect would be significant
(E) its effect on their size is not likely to be significant
    答案是E，没有问题。

     想问：it is unlikely that 这个表达是不是必错的？？读起来好象很拗口

it is unlikely that 这个表达本身并非必错：

It is unlikely that newly discovered gold deposits will ever yield as much as did those deposits discovered during the original gold rushes.

It is unlikely that a satisfactory explanation can be found to account for the increase.

it is unlikely that evolutionary mechanisms could discriminate against sinistral snails

However, if there is discrimination against one sex, it is unlikely that the degree of discrimination by government and private employers will be the same.

Without the debates among linguists that preceded them, it is unlikely that scientists would ever have begun to explore the essential role played by mathematics in the acquisition of scientific knowledge.

太感谢GEMJ兄了！！！！这么忙还帮我找了这么多例证！！！！！

    还有个疑问：如果it is unlikely that 本身无错误，那么A错在那里呢？？

gemj

(A) it is unlikely that its effect on their size is significant
的错误有人说在于IT存在双重指代，IT既是形式主语，ITS又指代了别的。

但因为在同一个句子里同一个代词的主格与物主形式可以指代不同的对象，我的理解是A没有E来得直接。

但我不是很确定。还请大牛指正。

dreadpower

我也这么认为，it应该没有问题，“同一个句子里同一个代词的主格与物主形式可以指代不同的对象”，有真题例证啊，

      请教牛人指点

it's unlikely如果在划线部分，不优选，应该选表达更加清楚的not likely， 因为：unlikely有歧义。如同：hopefully

dreadpower
