OG12 SC131 A选项while 查了老帖没有人问过

bujieyu

Over 75 percent of the energy produced in France derives from nuclear power, while in Germany it is just over 33 percent.

A. while in Germany it is just over 33 percent
B. compared to Germany, which uses just over 33 percent
C. whereas nuclear power accounts for just over 33 percent of the energy produced in Germany
D whereas just over 33 percent of the energy comes from nuclear power in Germany
E compared with the energy from nuclear power in Germany, where it is just over 33 percent
答案是C。
想问一下A选项的解释。While is somewhat ambiguous,since it might indicate simultaneity rather than contrast......
OG说while更有可能指同时性而不是对比，请问在gmat中while表达对比的意思吗？
附上朗文的while释义：
while1   conjunction
1 during the time that something is happening:
They arrived while we were having dinner.
While she was asleep, thieves broke in and stole her handbag.
She met Andy while working on a production of Carmen.
2 all the time that something is happening:
Would you look after the children while I do the shopping?
3 used to emphasize the difference between two situations, activities etc:
Schools in the north tend to be better equipped, while those in the south are
relatively poor.
4 in spite of the fact that SYN although:
While never a big eater, he did snack a lot.
While there was no conclusive evidence, most people thought he was guilty.
5 while I’m/you’re etc at/about it spoken used to suggest that someone should
do something at the same time that they do something else:
Print out what you’ve written, and while you’re at it make a copy for me.

BY上说while可以表示转折，我感觉OG是说用while会产生歧义。

另外A中的it指代的是Over 75 percent of the energy，Over 75 percent of the energy is just over 33 percent，逻辑错误。
