题目分析：
略。
选项分析：
A选项：比较对象不对等。本题想比较的不是两个年份，而是两个年份的价格。检查本选项最合理的比较对象可知，我们真正应该比较的是“现在的价格”和“一年前的价格”。如果只用now，相当于比较的是“一年前的情况”和“现在的情况”，这是不对的。因为“价格的情况”和“价格”是不同的，只有价格才能higher（高低），价格的其它情况或者属性是没有高低之分的。
B选项：Correct. 本选项在逻辑和语法上均是正确的。
C选项：比较对象错误同(A)。
D选项：higher+than是习惯表达，不能加as。
E选项：本选项错误同(D)。
2、前一个句子带了时间时间状语，被比较部分可以省略主体结构，只留下时间状语。
3、prices of a year ago是可以的，查到一个句子：to buy it at the prior year price，说明price+of+时间状语可以表示某个时间点的价格.但是这个坑设的实在不咋的，对非native非常不友好，鄙视GMAC
而主動詞一致性, 平行結構, fragment sentence, 邏輯, 時態錯誤等等屬於絕對考點（必對必錯）, 可優先刪除錯誤選項
上面的Ａ選項雖然沒有補出those代名詞指代另外一個群體的prices, 但這部分是屬於扣分點, 並非必對必錯
真正的錯誤是如同上面林兄所說, are hurting & raised的時態(邏輯）錯誤
不太可能是corn and soybean價格提升之後才發生hurting crops這件事

i guess "that of" has a little more leeway in the exact parallelism department.
i.e. you can put "that OF" or "those OF" in parallel to anything that suggests a possessive structure. or at least that's what we learn from this problem...
in any case, you can't use "IN any other...", because there's nothing to which the preposition IN can be parallel.
这里觉得判断的依据应该还是后半句的时态问题。
Prices at the producer level are only 1.3 percent higher now than（Prices at the producer level were） a year ago and are going down, 所以补充完整会发现应该是在比较价格，而不是时间了

A are hurting and raised are blatant shift of tense. So gone.
C This is a fragment; the conjunction ‘and’ creates confusion as to what are hurting crops and raising. They seem to point to the subject the sentence prices at producer level;
However, note that the action of hurting is in present progressive tense and hence, means that it is an ongoing action, while the verb raised is in simple past tense. This is illogical since result cannot precede the cause. Therefore, we have a verb tense error in this sentence.
C选项：比较对象不对等
D选项：比较接＋than；
E选项：hight than;
