OG83,OG35 关于it指代

35.         In June of 1987, The Bridge of Trinquetaille, Vincent van Gogh’s view of an iron bridge over the Rhone sold for $20.2 million and it was the second highest price ever paid for a painting at auction.

(A) Rhone sold for $20.2 million and it was

(B) Rhone, which sold for $20.2 million, was

(C) Rhone, was sold for $20.2 million,

(D) Rhone was sold for $20.2 million, being

(E) Rhone, sold for $20.2 million, and was

why "it in A has no logical referent", 我觉得很明显it refers to The Bridge of T, 怎样才算指代,是不是要主格的代词指句中的主语,宾格指代宾语成分?

83.         Any medical test will sometimes fail to detect a condition when it is present and indicate that there is one when it is not.

(A) a condition when it is present and indicate that there is one

(B) when a condition is present and indicate that there is one

(C) a condition when it is present and indicate that it is present

(D) when a condition is present and indicate its presence

(E) the presence of a condition when it is there and indicate its presence

请说明为什么C对,而其它不对如indicate that there is one/its presence when it is not.

那不是变成有指代了吗？怎么ETS说无指代呢？

我觉得，如果A变成Rhone sold for $20.2 million， and it was
里it可以指向$20.2 million，这里it最多说指代不清，怎么可以说没有指代对象呢？？

ETS说的是A has no logical referent. 而不是no referent

题目中的vincent.....million是起到同位语作用的成分按A那样说it指代的就是那幅画而不是price所以是no logical referent.

看了讨论，可是问题并未得到解答。请NN再帮忙看看。

35.   In June of 1987, The Bridge of Trinquetaille, Vincent van Gogh’s view of an iron bridge over the Rhone sold for $20.2 million and it was the second highest price ever paid for a painting at auction.

(A) Rhone sold for $20.2 million and it was

(B) Rhone, which sold for $20.2 million, was

(C) Rhone, was sold for $20.2 million,

(D) Rhone was sold for $20.2 million, being（C）

(E) Rhone, sold for $20.2 million, and was

A comma is needed after Rhone in choices A and D to set off the modifying phrase that begins Vincent...; without the comma, the phrase appears to be part of the main clause, and it is thus unclear what noun should govern the verb sold. Furthermore, it in A has no logical referent, and being in D is not idiomatic. Choices B and E produce the illogical statement that the painting was the second highest price. Choice C, the best answer, avoids this problem by using a noun phrase in which price clearly refers to $20.2 million. And by using a comma after Rhone to set off the phrase that modifies The Bridge of Trinquetaille, C makes the painting the subject of was sold.

想问，it 在这种句型里，到底是就近指代$20.2 million (if possible?),还是指代前句话的主语The Bridge of Trinquetaille？

谢谢了。
