Hi Ron, In the "clause, v-ing" structure, does v-ing always modifies the entire clause indicating either things happen at the same time or results of the clause? I don't understand why "they" is not a correct subject for "consist" in Choice A. Is it illogical because th...

I don't see a definition of natural number in OG. Does GMAT test natural numbers?

Thanks.

Thank you, Ron!

GMAT PREP SC Three out of every four automobile owners in the United States also own a bicycle. A Three out of every four automobile owners in the United States also own a bicycle.

No. In constructions like this one, it's understood that "a bicycle" refers to a bicycle for each owner. That's not unique to this sentence: Most students at this university ride a bicycle to class. It's December, so 9 out of 10 New Yorkers will be wearing a black overcoat. etc. The conte...

Thanks a lot, Ron. Your posts are always very helpful!

Can someone please explain why (A) is wrong? Is it wrong because it has nothing to do with the range (where guillemots are able to live)?

Thanks in advance.

Thank you, Ron.

Thank you so much for the thorough explanations, Ron! You are the best!

Can someone please help me understand why is "it" in choice B unambiguous? Does "it" refer to Morocco?
Does "assumed" imply that we need to use the conditional?

Thanks in advance.

Those are two of the most common ways in which that kind of modifier is used. There are also others -- for instance, the modifier might give an illustration or explanation of what's in the main clause that it's describing. Just ask yourself whether the modifier is reasonably a description of the st...

I believe Terrace incorrectly quoted the second "wrong sentences from OG." This is OG13 #74. I don't find any answer choice that is the same as the one Terrace quoted. The correct answer is "Although it covers the entire planet, Earth's crust is xxxx." And one of the wrong answer...

The subject is rising prices, not rising, so are is required to match the plural subject.

dear Ron/instructors I got a question: why can't I interpret (a) as this:imposing stricter limits on medical services and requiring doctors to see more patients, and (to) spend. by that I mean:imposing and requiring are parallel; to see and (to) spend are parallel Thanks a lot! that interpretation ...
