it's in the correct answer, so, yes.

maybe i don't understand what you are asking -- but, if you are asking "Is the correct answer *really* correct?", then, well, yes it is.

Ron,

As you explained in the post, in which you have pointed out the following example and mentioned the construction (preposition) + NOUN + VERBing is usually WRONG.
i've never heard of bees stinging dogs

Therefore, I thought the construction the interaction of two stars orbiting each other is wrong. While I understand that in certain cases this construction,as in the following example given by you, can be correct. But usually GMAT doesn't prefer such choices.

For instance it is correct in the following scenario:
i have a picture of my cousin playing hockey.

Let me know if my understanding is correct. Can we consider the correct choice of this question as one of the example where this construction is correct.

Thanks

This actually fits with Ron's later post in that same example where he said:

if you have "preposition + NOUN + VERBing", then "VERBing" is just a modifier, and can be dropped without changing the surrounding grammar.
therefore, the sentence should still make sense, in context, if you write it as just "preposition + NOUN", without the "VERBing" modifier.


If we break down the original sentence:
A number of astronomical phenomena are caused by the interaction of two stars (orbiting each other at close range)

The phrase "orbiting each other at close range" is simply a modifier that gives us a better idea of what sort of "interaction of two stars" we are talking about.

Dear Ron: First of all, I would like to extend my sincere appreciation for your help along my GMAT way. I have reviewed more than a hundred answers you wrote before I registered just now:) I told my mom on the phone that there's a man called Ron who helped me a lot, but he doesn't even know there's a me:)

Then, I would jump to my questions. For question A and B, you said [the construction is REDUNDANT if you include both "likely" and "may" you can only have one of those]. Later when you answer an student's question about there's no redundancy for "seem likely", you wrote these[ if something seems likely, that doesn't necessarily mean that it is so -- it only seems that way.
e.g.
although rain may seem likely today, it's not going to happen -- so you can leave your umbrella at home.
this sentence makes sense. if you try to replace "may seem likely" with "may be likely", the resulting sentence will be nonsense.]
If my understanding is right, is it a typo, do you mean "although rain seems likely today"? because may and likely and redundant,as you said before.
Thank you for your reply.

well, ok, this one is context-specific. it only makes sense because that sentence is addressed to another person.

note the context in which that sentence would make sense:
to the listener, rain seems likely (or may seem likely—the speaker doesn't really know for sure)
• to the speaker, rain does NOT seem likely.

in this context, the "may" serves two purposes:
1/ it makes the sense softer and more polite;
2/ it refers to the uncertainty of whether the other person thinks that it's likely to rain. it does NOT refer to the uncertainty of actual rainfall.

(#1 is obviously not a concern on the gmat, or in written language in general—good writing would very often be characterized as "rude" if spoken out loud.)

by the way, the distinction above is essentially irrelevant on the exam; they will not make you understand the role of SC sentences in conversational interaction.
if the sentence occurs from a single perspective, or is factual, then "may" + "likely" is redundant.

Hi Ron~~

Are "each orbit the other(B)" and "each is orbiting the other(D)" are wrong ? I think we should write "orbit each other."

In addition, "in orbiting" is another reason to eliminate (D) ?

Please correct me. Thank you in advance :)

not really.

this would also be an acceptable way to write the sentence:
... are caused by the interaction of two stars, each orbiting the other.

fortunately, there are much more straightforward ways to eliminate these choices (redundancy for B, "where" for D).

I think we should write "orbit each other."


"X is correct" does not imply "Y is incorrect".

i don't see this phrase in choice D.

in fact, i don't see this phrase in any answer choice.
