if choice D said 'less' it would be fine. the only problem with that choice is that 'lower' cannot modify actions.

bsence of any general inflation or deflation 谓语用单数，所以B错……主谓一致啊

读懂句意，from to

"Lower" and "greater" can't be used to compare actions.

The meaning should be clear: The costs rose by 2.8% this past year; in the previous year, they rose by more than 2.8%. So, this year, they rose less than they did last year.

前面的more than，后面的less than

Disraeli是个人名………………服气
直到1868年英国才有一个总理D，不是来自地主家庭

解释D：A situation cannot be releasing torrents of water. Thus, the second present participle makes the sequence illogical. (Furthermore, even if RELEASING were logical, it would have to be connected to CAUSING by AND, and there is no AND.) E：to burst and release 平行

than usual/ ever before/ previously expected/previously estimated/ anticipated…

这里that是表结果吗

E being a united states citizen since 1988 不好
A and前后时态不一致 不好

转自beatGMAT 在前句出现过的部分可以在后面省略
A: Of all the record companies involved in early jazz, the three most prominent [?] were Columbia, Victor, and OKeh.
D: Columbia, Victor, and OKeh were three most prominent [?] of all the record companies.
Here, it is NOT crystal clear what words are implied within the brackets since no eligible phrase appears earlier in the sentence.

注意看清题干：是问对于ALH84001 originated on Mars这一个观点的看法，这一观点在第一段开头几句里面已经说清楚了，这个是个已经被广泛接受的事实。

“Yet mergers and acquisitions remain common, and bidders continue to assert that their objectives are economic ones”可以看出，他们并没有达到

Acquisitions may well have the desirable effect of channeling a nation's resources efficiently from less to more efficient sectors of its economy, but the individual acquisitions executives arranging these deals must see them as advancing either their own or their companies' private economic interests.

请问怎么理解这句话后后面的结构啊，看起来好怪：... the principle that form follows function and incorporate readily available materials fashioned using traditional skills. 这里的that后面有两个并列的动词form和incorporate，但是the principle是单数，所以that是修饰crafts？ 还有，that form follows function这里follows又是啥啊>-
