The Organization of Petroleum Exporting Countries (OPEC) had long been expected to announce a reduction in output to bolster sagging oil prices, but officials of the organization just recently announced that the group will pare daily production by 1.5 million barrels by the beginning of next year, but only if non-OPEC nations, including Norway, Mexico, and Russia, were to trim output by a total of 500,000 barrels a day.

(A) year, but only if non-OPEC nations, including Norway, Mexico, and Russia, were to trim output
(B) year, but only if the output of non-OPEC nations, which includes Norway, Mexico, and Russia, is trimmed
(C) year only if the output of non-OPEC nations, including Norway, Mexico, and Russia, would be trimmed
(D) year only if non-OPEC nations, which includes Norway, Mexico, and Russia, were trimming output
(E) year only if non-OPEC nations, including Norway, Mexico, and Russia, trim output
我想表达的所谓”平行结构“在OG13-SC52得到了印证。...compound sentence would be most clearly expressed if JB were the subject of the first clause sine 'she' is the subject of the second clause.
另外想请教的是C中解释，Would在be trimmed之前是redundant的。不过这题如果是说X will do sth only if Y does sth, 那其实凭时态已经可以区分了，为什么OG还要特别提一句redundant呢？如果表述为 is trimmed就会出现B选项的不清晰。这样写了其实有没有什么特别的地方呢？谢谢

就是因为是X will do sth only if Y does sth所以would是多余的。 关于redundant，manhattan是这么解释的：Eachword in the correct choice must benecessary to the meaning of the sentence. No right answer on the GMAT will containredundant words.
