Official Explanation
Difficulty Level: 650


Answer: A

Explanation

You should use analyzing at the beginning of the phrase, because that’s what the satellites did. Because NASA launched two satellites, it’s incorrect to refer to them as a technique; eliminate B and E. C is incorrect because to the analysis is not idiomatic. And you can cross off D because to analyze is not complete. It would have been better if the sentence had said used to analyze

Hope it Helps

In order for parallelism to work you have to have "equal" elements. When i say "equal" i mean a "list" of nouns or verbs or "noun clauses", etc - you get the idea.

Here in this construct, when the sentence is "parsed",

To determine, whether there are deposits of frozen water on the moon, research scientists at NASA launched two unmanned satellites that orbited the moon's atmosphere, to analyze radar echoes from the lunar surface.

If "parallelism" were to work correctly, the construct in red would have to be equal [in terms of grammatical construction and "level" of hierarchy when you sentence diagram, etc. Also remember there isnt a conjuction in between the 2 seemingly parallel constructs ] to the construct in green

The "," after the atmosphere was a give way that "to determine" and "to analyze" arent parallel.

I'm curious what is the source of this question. I dont think there should be a "," after "to determine".

I thank all of you for participating. The Answer is A. The source of this question is the Princeton Verbal Workout book

The OE is as follows:

You should use analyzing at the beginning of the phrase, because thats what the satellite did. Because NASA launched two satellites, it's incorrect to refer to them as a technique;eliminate B and E. C is incorrect because "to the analysis" is unidiomatic. And you can cross of D because to analyze is not complete. It would have been better if they had said used to analyze

Thank you very much gmataquaguy, you helped me clear my parallelism concepts.

I thought this fell under the parallelism of gerunds.
This example is straight from my notes

Gerunds go with gerunds, and infinitives go with infinitives. Don’t mix gerunds and infinitives.
Wrong: Skiing is as strenuous as to rappel down a cliff.
Right: To sky is as strenuous as to rappel down a cliff

That is why, I thought "to determine" is parallel to "to analyze".

Thanks

Can you please explain why to analyze "is not complete".....!!

Analyzing seems reasonable....but on what basis we opt out to analyze.

Hi AJ8348.

D is wrong for sure. Let me give you another example
The computer system was upgraded TO AVOID stealing information.

You think this sentence is correct or not? It's definitely wrong.When you see infinitive, let examine the subject. Make sure the main subject and the infinitive are sensible. Can the computer system avoid stealing info by itself? Not, It cannot. So, we can change the sentence like:

The computer system was upgraded TO KEEP IT from stealing information.

The problem in D is the same. Can two unmanned satellites analyze radar echoes? No, they cannot do so by themselves. D should be changed like: To be used for analyzing.......

Does it help?. Let me know.

Regards.

I went for A because the modifier refers to satellites.

But I think E is fine also. Does anyone have a clear explanation on why E is wrong?

satellites orbited. how did they orbit? this how is explained by "the comma+analyzing" modifier. so A is correct.
E - what does 'technique" refer to? orbiting? launching? this choice is wrong because of no clear referant for this modifier.

Hi,

the Verb+ing modifier should modify the subject of the preceding clause. So in this case, isn't 'analyzing' modifying ' research scientists at NASA '? This will alter the intended meaning.
Am I missing anything here?

Satellites orbited is the previous clause and analyzing refers to subject satellites and analyzing explains how satellites orbited.
