Dear Friends,
Here is a detailed explanation to this question-
Arlene0504
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
Choice A: Option A incorrectly compares "prices" to "a year ago" and does not maintain parallelism between the verbs "are hurting" (present continuous) and "raised" (simple past). Thus, Option A is incorrect.
Choice B: Option B correctly compares "prices" to "those (prices) of a year ago" and maintains proper parallelism and conjunction use throughout the sentence. Thus, Option B is correct.
Choice C: Option C repeats the comparison error displayed in Option A. Thus, Option C is incorrect.
Choice D: Option D uses the conjunction "as"; as this conjunction does not signify contrast, its use alters the meaning of the sentence. This answer choice also fails to maintain parallelism between the verbs "hurt" and "raise". Thus, Option D is incorrect.
Choice E: Option E repeats the conjunction error found in Option D and incorrectly implies that the "prices" are hurting crops. As the phrase "despite floods in the Midwest and drought in the south" is included between two commas, the modifier "and are hurting crops..." will refer to the subject of the previous clause.
Hence, B is the best answer choice.To understand the concept of “Extra information between Two Commas on GMAT”, you may want to watch the following video (~1 minute):
