Thank you Tim, I take your idea.

My question is that

I contend that gmat is hard.

in above sentence, "contend" alway needs "that" . is that right?

the following sentence

I contend gmat is hard.

is wrong.

so,
contend that+clause is idiom
contend +clause is not idiom

is that right?

[tim]

Yes, your analysis of these specific examples is correct. It seems like you are interested in a general principle here, and I would say that in most cases you should include a "that" between the main subject/verb and a subordinate clause, as you have done here..

What about "A metabolism" and THE matabolism"?

If B changed into the metabolism of many D S was more like~,
would B be the answer? or "the metabolism" still has to change into "a metabolism because of the not underlined part ?

nope -- in that case, you'd end up with an ambiguous sentence.

you'd have "A was more like B than C".
the problem is that this could mean ...
1/
there was more similarity between A & B than between A & C
or...
2/
there was more similarity between A & B than between C & B.

the correct answer is written in such a way as to eliminate this issue. luckily for you, it's not tested in the problem at hand.

Dear Experts,

I'm confused by this question. Can we legitimately compare in choice A noun "metabolism" with posessive nouns such as "warm-blooded mammel's?

Some scientists contend that many species of dinosaur had a metabolism more like a warm-blooded mammal’s than a cold-blooded reptile’s.

A. that many species of dinosaur had a metabolism more like
B. that the metabolism of many dinosaur species were more like
C. that the metabolisms of many species of dinosaurs were more like those of
D. there were many species of dinosaurs that had metabolisms more like those of
E. there were many dinosaur species that had a metabolism more like that of


Tell me what you think, and I'll give you the surprising answer

I do not understand why in choice A though there is no "of" at the begining, we can still use "apostrophe+s" at the end

I think to use "apostrophe+s" we need "of "phrase at the begining.

please, explain this point. in the previous posting, Ron did not say this point clearly.

--> "is the official answer correct?"
yes.
always.
end of story.

if you encounter an unfamiliar construction in one of the official answers, don't question it; it's not wrong. instead, just learn how it works, and remember it in the future.

[tim]

Anytime you see a possessive without a noun after it, you should infer the existence of whatever prior noun in the sentence is obviously supposed to be the object of the possessive. That should clear up any concern about parallelism here.

the correct answer is written in such a way as to eliminate this issue. luckily for you, it's not tested in the problem at hand.

so to avoid these ambiguous things, we need a structure of correct answer.

e.g.,X have A more like B than C

am i right?
can someone help me ? thank you in advance

[tim]

Perhaps I'm not clear on what you're asking. You always need "a structure of correct answer [sic]" on sentence correction problems. That's the whole point of sentence correction.

[RonPurewal]

I can't tell what you are asking, either.

Tip:
If you just type a whole bunch of stuff followed by "Am I right?", we will rarely be able to tell what, SPECIFICALLY, you're asking about.
Please try to include specific questions.

Also, my head is spinning from all these A's and B's and C's and so forth.
When you post a clearer version of your question, please try to write actual examples——i.e., with actual words/phrases where there are currently "A"/"B"/"C"/etc.

"Formulas" can't account for context, so they can only work for issues that don't depend on context at all. There are VERY few such issues, so, in general, sentence correction "formulas" will have almost no value. (Maybe even negative value, if they cause you to miss important factors in the context of a sentence.)

Dear Ron，

many species of dinosaur had a metabolism more like a warm-blooded mammal's than a cold-blooded reptile's.

In choice A.

many species of dinosaur had a metabolism more like a warm-blooded mammal's
This part is not comparison.

The comparison is between warm-blooded mammal's and a cold-blooded reptile's.


And we cannot compare many species of dinosaur and a warm-blooded mammal's . It's right?

[RonPurewal]

the metabolism is more like xxxx than like yyyy.

[RonPurewal]

i'm skeptical of the authenticity of this problem. can someone post a screenshot from the GMAT PREP software?

no further discussion until such a screenshot is posted. thanks.

[gmatkiller_24]

Hi, Ron:

what you mean in B is a singular-plural mismatch.

so, from the perspective of logical meaning

→ what B tried to convey was that many dinosaurs share one single metabolism, a fact that is illogical. Is that right ?
