We have to determine what the subject is in this question: what might force a rethinking, since it cannot be Last Year, in full view, it eliminates D and E, leaving us A,B and C.
now B and C can be eliminated since thus possibly and thus may possibly forcing sounds wrong, the word 'possibly' sounds plain wrong, when used with 'may' or 'thus'.

That leaves us only with choice A.

(E) Last year, in full view of ground- as well as space-based telescopes, the spectacular disintegration of a comet has provided new insights into how comets form and may thus force

nothing wrong with A here.

B: as well as is wordier than "and" and is not needed here. and thus possibly forcing is awkward and could be better said as: and may thus force.
C: "it" has no clear referent.
D: thus possibly forcing is incorrect.
E: again as well as is wordier than and

Also I think some of the meaning is lost when you change around the sentence as done in D and E.

There is no tensed verb in choice B at all, so this answer violates parallelism. This is a great example of there being more than one way to skin a cat-- I'd venture that a lot of people would get hung up on the "and" versus "as well as" distinction, which is less common. It's my understanding (and if someone knows this for sure I'd love to hear your thoughts) that "and" is necessary to justify the hyphen usage here ("as well as" usually follows a comma and starts out a modifying phrase that does NOT change the singularity/plurality of a noun)--but if you weren't sure about that distinction it's best to go for what you DO know and not get hung up on what you don't. (C) When [strike]a comet's spectacular[/strike] disintegration occurred [strike]in full view of ground- and space-based telescopes last year[/strike], it provided new insights[strike]into how comets form[/strike] and thus may possibly force. The meanings of "may" and "possibly" overlap, so this phrase is redundant. Lose it. (D) Last year, [strike]in full view of ground- and space-based telescopes,[/strike] [strike]a comet's spectacular[/strike] disintegration provided new insights [strike]into how comets form[/strike] and thus possibly forcing Choice D has the same issue as choice B with lack of a tensed verb. Additionally, the placement of the modifier "in full view..." implies that the providing of insights was what happened in full view of the telescopes. Lose it. (E) Last year,[strike]in full view of ground- as well as space-based telescopes,[/strike] [strike]the spectacular[/strike]disintegration [strike]of a comet[/strike] has provided new insights[strike]into how comets form[/strike] and may thus force I agree with rlevochkin-- this is an incorrect use of the present perfect tense. When you pinpoint a specific point in time, you cannot use the present perfect. In 1998, I have eaten the best pie ever made. INCORRECT In 1998, I ate the best pie ever made. CORRECT Last year, I have gone to school. INCORRECT Last year, I went to school. CORRECT You CAN, however say "Since [a specific point in time]" -- Since 1998, I have lived in Santa Monica. CORRECT That only leaves A! _________________ JP Park | Manhattan GMAT Instructor | Los Angeles Manhattan GMAT Discount | Manhattan GMAT Reviews Forum Moderator Status: mission completed!

(E) Last year, in full view of ground- as well as space-based telescopes, the spectacular disintegration of a comet has provided new insights into how comets form and may thus force

A for me too. I was stuck between A and E.
I rejected E on two grounds: the use of commas which makes the second phrase a non-essestial modifier which is not the case here. The phrase " in full view of ground- as well as space-based telescopes" is essential to meaning of the sentence, so the use of commas is not justified. Secondly, the use of perfect tense is not necessary. The action has already occured and simply requires a present tense. The infromation derived from that action may be present but the action is already over. Also, you do not need a present perfect when you are talking about a specific point of time in the past that has already occured.

If you can remember two basic things in the given context, the answer will pop up.

1. The co-ordinate conjunction - and – joins two equal things and so if you have a clause on one side of the -and - you must necessarily have another clause on the other side. Otherwise the sentence is un-parallel. So B and D are out for using the incomplete phrase thus possibly forcing after the co-ordinate conjunction – and-

2. The disintegration occurred last year. The adverb last year must not be far removed from the disintegration.

The misplacement of the adverb -last year- after - telescopes in C and - before in full view of ground - in E, fouls this structural rule.

Then we are left only with A.

The point is that in a pressure-cooker test such as GMAT, if you can spot at least one error in a choice, then dump it and get going than pull your hair on fine prints. Any takers?

In Option B

, provided new insights into how comets.... is acting a modifier for the first part of the sentence.

However if we look closely than the first part below has no verb and hence a sentence fragment.

"The spectacular disintegration of a comet last year in full view of ground- as well as space-based telescopes"

This is precisely my Query and I am tired of beating my head over it.
RULE states that: Verb-ed modifier modifies the closest NOUN.

Now looking at the statement which is Correct: The spectacular disintegration of a comet last year in full view of ground-and space-based telescopes provided new insights into how comets form and may thus force

It is being assumed that "provided" is modifying 'the spectacular disintegration'. However, as per the above mentioned RULE, telescopes is the closest noun and the verb-ed modifier(provided) should be modifying Telescopes.

What am i missing here? Just following the rules and apparently stuck.

Please Experts or even anyone. Kindly look into this.

Provided in this context is NOT a modifier, it is a full verb.

Example: I provided him with food.

In B, "provided" is a modifier because it is being set off by a comma.

B and D out because of "thus possibly forcing"

C is out because of "it"

Now, between A and C , i saw the A has simple past with "last year" and E has "past perfect " with last year
from my previous knowledge i thought E is thus wrong
