support用法 （机经中的） &请教sell 用法

gemj

support for classifying...
support to do something...
好象都不对。正确的有：
support somebody in (doing) something
例如：
A multi-dimensional approach has the potential to discover and support creative processes in the local community.
If you are new, decide which senior colleagues would support you in your work.

既然在OG的正确选项中出现了，就是对的。再例如：
(B) A beautiful work of art is more valuable than the money it could be sold for, whatever the amount.
另外，LONGMAN上还有：
sell something for £100/$50/30p etc
Toni's selling her car for £700.
我想如果把这个句子改为被动就是be sold for。

不过我也有一问，这个题目的C选项如果改为
(C) Rhone, sold for $20.2 million,
是否也对？
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

因为LONGMAN上有这样的用法：
sell at/for £100/$50/30p etc (=be offered for sale at £100/$50/30p etc)
Smoke alarms sell for as little as five pounds.
