请教og11-32，看og的解释如入云雾

请问下面加红色的字体，是什么意思？

无法看懂，it为何要跟inflation平行呢？

32.      The Commerce Department announced that the economy grew during the second quarter at a 7.5 percent annual rate, while inflation eased when it
    might have been expected for it to rise.

A it might have been expected for it to rise

B it might have been expected to rise

C it might have been expected that it should rise

D its rise might have been expected

E there might have been an expectation it would rise

Idiom

The correct idiomatic expression is
    x is expected to y. In this sentence, the construction must remain idiomatic even when a different tense is used: might have been expected to rise.

A For it to rise does not complete the idiomatic expression correctly

B Correct. In this sentence, to rise completes the idiom correctly.

C That it should rise does not complete the idiomatic expression correctly

D         Its rise is not parallel to inflation
     and introduces an awkward clause

E       This construction is unnecessarily wordy

答案是B，但是你选项的内容打错了啊~~

红线的意思:"its rise"就是指代前面的economy grew

题目中有“while"表示对比，所以啊，要平行的~！就是说A怎么样，同时B怎样了……

个人理解

不好意思，我重新输入了。

我承认D是错的，但是单独把句子提炼出来

我看不出来需要平行的地方在哪里？

如果说its的主格可能使用的不对，改换成the rise of it，我还可以理解，但是og的解释说its rise应该跟inflation平行。。。

刚刚看了下OG，觉得这道题考得不是平行吧，上面写的是IDIOM

有点迷糊啊~抱歉了LZ

In
English, x [is] expected to y is idiomatic usage: expected for it to
in choice A and expected that it should in choice C are thus
unidiomatic. Choice D awkwardly substitutes its rise for the pronoun it
as the subject of might have been expected; since it refers to inflation,
the subject of the verb eased, it is preferable as the subject of might
have been expected, the verb form corresponding to eased. Choice E
is needlessly wordy, roundabout, and vague. Choice B is best.

谢谢，很清楚

正確選項中，被期待的對象是 inflation ( it 指代)，原本被期待的結果則是 to rise，

但實際上現在 inflation 是 ease了。

如果是D選項，變成被期待的對象是 "inflation的rise (its rise)"，

 (那有沒有可能被期待的對象也可以是 inflation的ease呢?)

因此 改變了 "語氣"上的主語 (而非 it 指代的主語)，

所以OG解釋才會說它沒有跟  inflation平行，主要是從語意邏輯上來看的。
