IMO [spoiler](D)[/spoiler] as this event is simple past and no ongoing so (A) analyzing is out,rest just don't fit in

OA is A
But in A, isn't analyzing modifies atmosphere??
Even i chose D, but OE given was that it would have been a better option had it used 'used to analyze' insted of 'to analyze'.
Any opinions??

I also picked up A. Why do we treat analyzing as modifier? I reason that the satelittes did 2 actions simultaneously: they orbited the moon, while doing what analyzing the echos
Gerund form is used to stress an action happening alongside the one in the main clause

(a) and (d) both make conceptual sense. (a) probably makes more sense than does (d), but both are at least somewhat reasonable.
they have slightly differing meanings:
(a) [participial -ing modifier] implies that "analyzing..." was just something that the satellites did while they were orbiting
while
(d) [infinitive] suggests that this is the PURPOSE - the reason WHY the satellites were orbiting.
(d) seems less likely to me, since it's a bit weird to orbit for the PURPOSE of analyzing echoes (as opposed to collecting or intercepting such echoes, which would make a lot more sense).
HOWEVER,
(d) is incorrect because this sort of infinitive construction CANNOT be preceded by a comma.
it just can't.
that's really the only reason why (d) is wrong.

I went by the process of elimination and ended up with A.
B and C change the meaning or rather they make no sense. I eliminated E because moon's atmosphere is not a technique as the sentence implies.
Between A and D i went with D as a comma infront makes this a definitely wrong choice. So i chose A.

it cant be analyzing because analyzing is an ongoing event and it sounds as if the scientists launched the satellites while analyzing the data which does not make sense. D it is. E cant be the choice because E says launching the satellite is a technique. D it is D it is D it is!
200 or 800. It don't matter no more.

'Analyzing' can't modify 'atmosphere' because you need 'which' after comma if you want to modify atmosphere. Also IMO 'A' is correct because 'analyzing' is present participle and if it's used after comma it modifies the whole preceding clause.

you can't say that to use present participle the whole sentence should be in present tense, present participle can be used with any tense.Mayur Sand wrote:IMO [spoiler](D)[/spoiler] as this event is simple past and no ongoing so (A) analyzing is out,rest just don't fit in
