758. Prices at the producer level are only 1.3 percent higher now than a year ago and are going down, eventhough floods in the Midwest and drought in the South are hurting crops andtherefore 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 raise
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: 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.
答案:B

772. Heating-oil prices are expected to be higherthis year than last because refiners are paving about S5 a barrel more forcrude oil than they were last year.
A. Heating-oil prices are expected to be higher this year     than last because refiners are paying about $5 a barrel more for crude oil     than they were
B. Heating-oil     prices are expected to rise higher this year over last because refiners     pay about $5 a barrel for crude oil more than they did
C. Expectations     are for heating-oil prices to be higher this year than last year's because     refiners are paying about $5 a barrel for crude oil more than they did
D. It is the     expectation that heating-oil prices will be higher for this year over last     because refiners are paying about $5 a barrel more for crude oil now than     what they were
E. It is     expected that heating-oil prices will rise higher this year than last     year's because refiners pay about $5 a barrel for crude oil more than they     did

OG: the sentence connects a comparison between this year's and last year's heating-oil prices with a comparison between this year's and last year's crude-oild prices.
答案:A

想讨论下两题中的比较,因为在我看来两题中的比较用的是同一个结构,都是想要比较this year's price vs last year's price,并且句型结构也都是prices are higher now/this year than a year ago/last。那么为什么758里 than a year ago 就被列为是错误的一个原因,会导致illogical comparison,而772中即使OG指出是this year's price和last year's price比较,却可以用higher this year than last? 谢谢!
