1.) Notice that the end of some of the answers include a subject/verb, so check sentence structure. ABCD each uses ", but" or ", yet" and each of these requires an independent clause on each side (S/V ", but" S/V). There is no verb after the underlined part, so we need a subject/verb in the answer after the ", but" or ", yet". This knocks out A and C. E doesn't need to be eliminated, because we don't have a comma before "but"

2.) We see "like" and "as" in the beginning, so comparisons are being tested. "like" needs to be followed by a noun. "as" can be followed by a noun or a subject/verb, but it is NOT a comparison if it is followed by a noun - it is describing function. Because we are comparing how the stars are in motion to how the planets are in motion, "as" needs to be followed by a subject/verb if it is used.

3.) The order of "stars" and "planets" changes, which usually indicates a modifier-related meaning issue. Here the sentence is intending to tell us that the "stars" are "so far away from the Earth", not the "planets".

The stars, some of them at tremendous speeds, are in motion just as the planets are, yet being so far away from the Earth that their apparent positions in the sky do not change enough for their movement to be observed during a single human lifetime.

A) The stars, some of them at tremendous speeds, are in motion just as the planets are, yet being - "being" doesn't make this wrong. In fact, the GMAT sometimes starts a clause using being if it is trying to use the state of being something as the subject. What makes this answer wrong is the lack of a subject/verb after the ", yet"

B) Like the planets, the stars are in motion, some of them at tremendous speeds, but they are - There is a subject/verb after ", but" and there is proper use of "like". Also, the modifier "some of them" is properly modifying "stars". Don't worry that "them" might be a little ambiguous ("stars" or "planets") because ambiguity is a lower priority than improper sentence structure, improper like/as usage, and improper meaning from improper modifier placement.

C) Although like the planets the stars are in motion, some of them at tremendous speeds, yet - Again, no verb after ", yet"

D) As the planets, the stars are in motion, some of them at tremendous speeds, but they are - "as" is followed by a noun, so it describes the function that the stars are performing, which is not the intended meaning of the sentence

E) The stars are in motion like the planets, some of which at tremendous speeds are in motion but - The modifier "some of which" is describing planets as being far away from the Earth. This is not the intended meaning of the sentence.

A) The stars, some of them at tremendous speeds, are in motion just as the planets are, yet being -using of being is not preffered for this sentence ,makes it verbose

B) Like the planets, the stars are in motion, some of them at tremendous speeds, but they are
-bingo. Like is used to compare nouns and it is used to compare stars and planets here. The rest of the sentence is gramatically correct.

C) Although like the planets the stars are in motion, some of them at tremendous speeds, yet -Use of although and yet simultaneously makes the sentence less clear .
D) As the planets, the stars are in motion, some of them at tremendous speeds, but they are-Use of as is wrong in the sentence .As is used to compare clause ,Like is prefered

E) The stars are in motion like the planets, some of which at tremendous speeds are in motion but -Incorrect comparison.

The statements says that both the stars and planets are in motion , but since the stars are farther away from earth,human eyes will not be able to see them moving.

So,we need "but" in there to bring upon the actual meaning.Retain B and D.
Like the planets --> Compares the motion of stars with that of the planets . Correct answer
As the planets --> incorrect comparison as we are comapring the motion of planets with stars and not just the planets.

Hi kiranck007,

“be” is an auxiliary verb, is/am/are/war/were/will etc. are different helping verbs in different forms.

Now is/am/are/war/were/will etc. are considered verbs but “be” or “being” juts by itself is never a verb that can complement a Subject. “being” is what is called present participle. Present participles are not verbs that can complement Subjects. For example:

The work is being done.
Joe, being a naughty boy, never finished his homework on time.

Hope this helps.
Thanks.

Had no choice but to agree with (B), but the 'they' could refer either to the planets or the stars creating ambiguity. I think this is a question of the OG.
Anyways, it is meant to test the basic rule of Like/As, and also maybe a couple of other thinkgs such as using Although and yet together in the same sentence which is of course clearly wrong.

Will stick to (B) then
Cheers

Hi chetan2u / mikemcgarry

Can you please explain why there is no pronoun ambiguity in B.
B) Like the planets, the stars are in motion, some of them at tremendous speeds, but they are

THEY can also refer to planets.

I am facing a lot of issue in pronoun ambiguity issues and hence I am not confident in eliminating options on the basis of pronoun ambiguity.

Please assist how can I comprehend this topic.

First and foremost, pronoun ambiguity has low priority. Many correct answers actually have some level of ambiguity. Only consider it when you have exhausted everything else. (Ambiguity means uncertain, not wrong. It is much worse to be wrong than uncertain.)

Second, a parallelism rule tells us the following:

When two clauses are joined by a conjunction and the second clause begins with a pronoun as the subject, that pronoun should refer to the subject of the first clause.

Here, we have the following structure:

[Modifier], [Subject] [Verb], but [Pronoun] [Verb]

As a result, we have two clauses joined by a conjunction, so the pronoun subject of the second clause ("they") must refer to the subject of the first clause ("stars"). Because "planets" is in a modifier, it is irrelevant to the parallel consideration because it is not the subject of the main clause.

[Edited to make it easier to understand.]

In B, is 'the stars are in motion' modifier' or 'appositive'? if not, then WHY we block off 'the stars are in motion' by comma?
If I say:
Like you I'm the member of GMAT Club. So, should I use comma after 'you' like bellow:
Like you, I'm the member of GMAT Club.
also, 'them' and 'they' refers to what? Does it refer 'planets' or 'stars'?

1. "The stars are in motion" is the main clause. It is not blocked off. It is preceded by a prepositional phrase ("Like the planets"), which is separated by the comma before "the". Again the main clause is succeeded by a subgroup modifier ("some of them..."), which is again separated by a comma after "motion".

2. A comma is generally recommended after "like X".

3. The pronouns "them" and " they" refer to "stars". There are two ways to confirm in this case why these pronouns refer to "stars" and not "planets".
a. If a pronoun that is the subject of a clause has two possible antecedents, one of which is the subject of another clause within the sentence, the pronoun would, by virtue of parallelism, unambiguously refer to the subject antecedent. "Stars" is the subject of a clause and so is "they".
b. The pronoun "them" is within a subgroup modifier. Therefore it must refer to the group (i.e. "stars") that the sub-group modifier is modifying.

If a pronoun that is the subject of a clause has two possible antecedents, one of which is the subject of another clause within the sentence, the pronoun would, by virtue of parallelism, unambiguously refer to the subject antecedent.

Here "they" is the subject of a clause and so is the antecedent "stars". Hence this reference is unambiguous.

So, HOW do we understand that x (stars) is antecedent of y (they), and p (planets) is antecedent of q (them)?
Thanks expert...

Both "they" and "them" refer to "stars". A basic rule about pronouns is that all "they","them","their" and "theirs" must refer to the same antecedent. ( So is true for all he/him/his or she/her/hers etc.)

B. The comparison is b/w Earth & Stars which calls for 'like' to express similarity. 'They' in the latter half clearly refers to 'stars' so no ambiguity.

Be careful. Here, "but" and "yet" are being used as conjunctions, and "but" and "yet" are interchangeable when used as conjunctions.

I enjoy movies, yet I never get a chance to go.
I enjoy movies, but I never get a chance to go.

These are identical. "Yet" only means up until now when it is being used as an adverb.

You got the right answer, but you should not have eliminated A and C for using "yet." Also, why then is E wrong? It also uses "but" and might not need a comma.

Hi Kiranck007

If I read you comment correctly, you mean the clause "The stars being so far away.." is correct (subject: The stars; verb: being). "being" is not a verb, it's a noun (human being) or an adjective. The main verb in this sentence is "are" (but they are so far.....)

Hope this helps.
Thanks.

Additionally, "being" can be a gerund (basically an action acting as a noun). For example:

Being nice can be hard.

This is the most likely way that the GMAT will make "being" part of the correct answer. See OG13 SC#100

The stars, some of them at tremendous speeds, are in motion just as the planets are, yet being so far away from the Earth that their apparent positions in the sky do not change enough for their movement to be observed during a single human lifetime.

A) The stars, some of them at tremendous speeds, are in motion just as the planets are, yet being

the main problem with A is that "yet being..." can modifies one of 2 previous clause. This modifier is ambiguous

this modifier can modifies the farther previous clause if the logicness is clear. in this case, This modifier can modifier either one of 2 previous clauses because there is no clear reason for the modifier to modify the farther previouse clause.

this wrong choice is hard.
