What do you think is wrong with this sentence?
A leopard cannot run as fast as a cheetah can
I think the sentence should have can at the end.
Because everytime I have seen if we use LIKE
then we can use nonuns like this.
but if we use AS
then the actioned should be mentioned, as "he did" or here it is "the cheetah can".
Pls advise if I am wrong.
Sorry for the wait here...
This example comes from our Manhattan SC guide, and it's a really interesting question. What you're getting at is the idea that we can only use "as" to compare clauses and that clauses by definition are more than just a noun; they have verbs. Your sentiment and underlying principle are exactly correct. "Like" compares nouns; "as" compares clauses.
The thing about this example is that the "can run" after "cheetah" is implied and thus it is OK to just say "A leopard cannot run as fast as a cheetah." You are still comparing clauses, and since the GMAT prefers concise answers (note that I said "prefers," not "requires.), this is an acceptable modification of the sentence "A leopard cannot run as fast as a cheetah can run."
