at this point, i think we should withhold further judgment until somebody verifies the source of this problem. if it turns out that this is indeed an OFFICIAL problem from gmac, then we should continue to expound on the principles in it. if it's from a third-party source, then it's quite conceivable that the official line on this issue could be drawn quite differently, and so we should refrain from making ANY conclusions from this particular problem until we can find some sort of precedent in official materials.iamcste wrote:hi ron, thanks for your comments but I have some more questions. At times, second part of the comparison is challenging for me! I guess in SC comparison questions, GMAC plays with two important constituents in second part of a comparison question, sometimes they deliberately remove the verbs to create ambiguity in the sentences and sometimes they miss subjects such as the above case. my questions are:lunarpower wrote: here's the way you should think of it:
speeds much higher than are currently possible (this is what's written there)
you should think of this as
speeds much higher than (speeds that) are currently possible
1. if option E were " at speeds much higher than speeds currently possible" aka no verb, is it correct ? why do we need "are"? what prompts us to think that we need "are" ( other than the split is/are)
2. In the orginal option E, "speeds that" is implicit....I wanted to know in which cases do we have this liberty to assume that subject is implicit? In short, when do we use ellipsis?
looking fwd to your responses!
can anybody step up with a citation for the original source of this question?
