A is out since when we use whether the "or not" state is already intended.
B is out since the meaning and parallelism changes.

C- Seems to be okay. We have correct modifiers, verb, and parallelism. So hold.

D. to help to determine is wordy. Just to help determine is good. So out.

E. use of singular verb is for plural subject goals is wrong.

So I go with option C.

IMO B

A. The Mars Exploration Program established that the main scientific goals of the MSL mission are to help determine whether or not Mars could ever have supported life, as well as determining the role of water, and to study the climate and geology of Mars.-------main goals are being lists her so the list should be parallel. "whether or not" is redundant

B. The Mars Exploration Program established that the main scientific goals of the MSL mission are to help determine whether Mars could ever have supported life, as well as to determine the role of water, and to study the the climate and geology of Mars.------------the list is parallel here and redundancy has been removed. Correct

C. As established by the Mars Exploration Program, the main scientific goals of the MSL mission are to help determine whether Mars could ever have supported life, as well as determining the role of water, and to study the climad geology of Mars.------list is not parallel

D. As established by the Mars Exploration Program, the main scientific goals of the MSL mission are to help to determine whether Mars could ever have supported life, as well as determining the role of water, and to study the climate and geology of Mars------list is not parallel.
"to help to determine" is incorrect


E. As established by the Mars Exploration Program, the main scientific goals of the MSL mission is to help determine whether Mars could ever have supported life, as well as determining the role of water, and to study the climate and geology of Mars.-------.S-V issue and list is not parallel

How is the list parallel in B?. "as well as" is redundant. We say X, Y and Z. Not X as well as Y and Z.

IMO D

As established by the Mars Exploration Program, the main scientific goals of the MSL mission are to help to determine whether Mars could ever have supported life, as well as determining the role of water, and to study the climate and geology of Mars

To help is followed by the infinitive 'to determine' and the participle 'determining' in parallel, connected together through 'as well as'.

'To help' and 'to study' are also parallel after the helping verb 'are'.

i also chose B. Well the reason is "X, as well as Y, and Z" in this X is the main focus and Y is after thought
X :- to help determine whether Mars could ever have supported life
Y :- to determine the role of water
Z :- to study the climate and geology of Mars

X and Z makes the list so they have to be parallel
Plus in all other options A,C,D,E "determining the role of water" is acting a modifier. So i choose B

Could you help explain why you think the meaning is changed in B? Thank you.

I think that the answer is B, due to parellelism. Although, I am not very sure. :|

So far, most of the opinions have been tentative among B, C, D; it is difficult to assign a difficulty value in such fluid contexts. However, I feel since it is drawing so much of munching, it should be 750 + level

Hi daagh, Please let us know the OA. I guess most of them are tending towards B. But I'm not really sure how in B all 3 items as parallel?

since the presence of as well as. Please provide your explanation.

as well as is a additive phrase, it wont draw the compound verb AND. THE main scientific goal, the means we are talking about the main goal, hence only one goal and the verb should be IS. E maintains parallelism.

Experts please let me know is my logic is correct !! I don't see a problem with E

Thanks daagh for the succinct explanation.
However I would like to clear few doubts over here - In option B apart from the error "as well as determining to" are there any other errors or does the sentence distorts the intended meaning? Because I feel that option B is more direct than the passive construction used in Option C, so if there were no idiom error then B could have been a strong contender.

True; if there were no idiom errors in B, then there would be two correct answers. But the risk is that the question would be invalid.

Answer choice E states “...main scientific goal[s]...is to”

Goals, which is plural, should be followed by “are” not “is”.
