Prices at the producer level are only 1.3 percent higher now than a year ago and are going down, even though floods in the Midwest and drought in the South are hurting crops and therefore raised corn and soybean prices.
(A) than a year ago and are going down, even though floods in the Midwest and drought in the South are hurting crops and therefore raised
(B) than those of a year ago and are going down, even though floods in the Midwest and drought in the South are hurting crops and therefore raising
(C) than a year ago and are going down, despite floods in the Midwest and drought in the South, and are hurting crops and therefore raising
(D) as those of a year ago and are going down, even though floods in the Midwest and drought in the South hurt crops and therefore raise
(E) as they were a year ago and are going down, despite floods in the Midwest and drought in the South, and are hurting crops and therefore raising


og解释比较对象为“between such prices now and those of a year ago”
为什么此处必须是price的比较不能单纯比较时间now和a year ago呢？
困扰了好久
恳请各位发表下自己的看法

同意你的观点！我觉得很有道理啊~

我认为A就是错在了没有补充helping word，没有重复v来说明时态的不同，前半句如果写成Prices at the producer level are only1.3 percent higher now than they were a year ago就没问题了。b中通过those of巧妙地把比较对象变成了prices之间的比较，就如同a is higher than b（虽然有时间标志，但是这个时间标志是在those of里面的，成为了比较主体的一部分，所以不用补出were了）。ron的理论应该还是没错的。只是现在这题越来越tricky

RON could be wrong though. GMAT's comparison has a higher standard with regard to parallelism, which mean "now" could not be paralleled with "a year ago"; We could make things a little messier by stating that "last" could refer to “last year's crude oil price”

看到了！感谢！
不过这和og解释有矛盾呀。。

OG的解释有时候也不一定完美吧 我觉得楼主不用过分纠结这个点了 毕竟A有其他明显的错误 可以排除

楼主，请你把OG原文原原本本复制下来，我认为你并没有看清楚OG的解释。这样楼上的争论就毫无意义。 ...

OG解释：The sentence as written makes an illogical comparison between prices at the producer level and a time period (a year ago); surely the intended comparison is between such prices now and those of a year ago.
不是说这个比较是不对的吗？是我没理解对吗？
还请NN帮解释下
