Hello Everyone!

This looks like a great example of a question that focuses on parallelism! Whenever we see a question with a long list, parallelism is a great place to start narrowing down wrong answers.

Let's break down each answer to rule out answers that don't use parallel structure. We know that every item in the list has to be parallel to the one item on the list that isn't underlined: "ward off." Since we cannot change that part, we need to match all other items in the list to that!

A. Mars would have to endure low levels of gravity for long periods of time, avoiding large doses of radiation, plus contending --> NOT PARALLEL
B. Mars would have to endure low levels of gravity for long periods of time, avoid large doses of radiation, contend --> PARALLEL
C. Mars, having to endure low levels of gravity for long periods of time, would also have to avoid large doses of radiation, plus contending --> NOT PARALLEL
D. Mars, having to endure low levels of gravity for long periods of time, avoid large doses of radiation, plus contend --> PARALLEL
E. Mars, who would have to endure low levels of gravity for long periods of time, avoid large doses of radiation, contend with --> PARALLEL

We can rule out answers A and C for lacking parallel structure!

Okay, so this narrows things down a bit! Let's break down any other problems with answer B, D, and E:

B. Mars would have to endure low levels of gravity for long periods of time, avoid large doses of radiation, contend
This is CORRECT! It uses parallel structure and includes a verb to make this a complete sentence.

D. Mars, having to endure low levels of gravity for long periods of time, avoid large doses of radiation, plus contend
This is INCORRECT because by adding the comma and changing the verb to the gerund "having," this is now just one long run-on sentence. It is missing a verb!

E. Mars, who would have to endure low levels of gravity for long periods of time, avoid large doses of radiation, contend with
This is also INCORRECT because the comma turns this into a long run-on sentence that is missing a verb.


Don't study for the GMAT. Train for it.

A. Mars would have to endure low levels of gravity for long periods of time, avoiding large doses of radiation, plus contending (Items in red are not parallel)
B. Mars would have to endure low levels of gravity for long periods of time, avoid large doses of radiation, contend (correct)
C. Mars, having to endure low levels of gravity for long periods of time, would also have to avoid large doses of radiation, plus contending (Items in red are not parallel)
D. Mars, having to endure low levels of gravity for long periods of time, avoid large doses of radiation, plus contend (Lack of main verb)
E. Mars, who would have to endure low levels of gravity for long periods of time, avoid large doses of radiation, contend with (Travelers would have endure low levels of gravity not mars)

Travelers from Earth to Mars would have to endure low levels of gravity for long periods of time, avoiding large doses of radiation, plus contending with the chemically reactive Martian soil, and perhaps even ward off contamination by Martian life-forms.

A. Mars would have to endure low levels of gravity for long periods of time, avoiding large doses of radiation, plus contending
B. Mars would have to endure low levels of gravity for long periods of time, avoid large doses of radiation, contend
C. Mars, having to endure low levels of gravity for long periods of time, would also have to avoid large doses of radiation, plus contending
D. Mars, having to endure low levels of gravity for long periods of time, avoid large doses of radiation, plus contend
E. Mars, who would have to endure low levels of gravity for long periods of time, avoid large doses of radiation, contend with

The sentence explains a Hypothetical situation, hence a "would" is appropriate. C & D are out

In the non-underlined portion, we see "and" & "ward off", signalling a parallel structure, going by the meaning of the sentence, we require the three actions

i) to endure low levels of gravity for long periods of time
ii) to avoid large doses of radiation
iii) to contend with the chemically reactive Martian soil

parallel to "ward off contamination by Martian life-forms"

A does not maintain parallelism

Between B & E.

E is redundant, no need of "who".

B is more concise & hence correct.


Answer B.


Thanks,
GyM

Only B can be answer. avoiding can't modify previous part. A out. rest choices does not make any sense at all.

Travelers must experience these things when they travel from earth to mars;
Travelers would have to , List 1, List2 ,List 3 and perhaps even List 4.
Quote:
A. Mars would have to endure low levels of gravity for long periods of time, avoiding large doses of radiation, plus contending

A lacks parallelism.endure.......... avoiding......... contending.........NOT parallel so eliminate it.
Quote:
B. Mars would have to endure low levels of gravity for long periods of time, avoid large doses of radiation, contend

I have no problem with it because parallelism is correct in this option.so Keep it.
Quote:
C. Mars, having to endure low levels of gravity for long periods of time, would also have to avoid large doses of radiation, plus contending

Here we have two problems .
1.having to is wrong and even changes the meaning.B is far better than this option.
2.parallelism exists.so you can eliminate it without doubt.

Quote:
D. Mars, having to endure low levels of gravity for long periods of time, avoid large doses of radiation, plus contend

same problem as c.so eliminate it.
Quote:
E. Mars, who would have to endure low levels of gravity for long periods of time, avoid large doses of radiation, contend with

Here who is wordy because we don't need it as B is clearly giving the meaning without who.So eliminate.
Left out is [b]B[/b]. So its the winner.

Is "Endure" not a verb?..... having to endure sounds right to me .... to endure - verb in the infinitive form?

Here is a post for usage of 'having'. usually problem is with the meaning of the sentence. In most of the Gmat question use of having is only in wrong option, though not all.

In D, yes having to introduces a run on sentence, But if we see that as a modifier, then it wont be a run on.

Travelers from earth to mars, modifier, avoid(verb), contend and ward off. How is it a run on sentence then?

[quote="BFR"]Travelers from Earth to Mars would have to endure low levels of gravity for long periods of time, avoiding large doses of radiation, plus contending with the chemically reactive Martian soil, and perhaps even ward off contamination by Martian life-forms.


A. Mars would have to endure low levels of gravity for long periods of time, avoiding large doses of radiation, plus contending

B. Mars would have to endure low levels of gravity for long periods of time, avoid large doses of radiation, contend

C. Mars, having to endure low levels of gravity for long periods of time, would also have to avoid large doses of radiation, plus contending

D. Mars, having to endure low levels of gravity for long periods of time, avoid large doses of radiation, plus contend

E. Mars, who would have to endure low levels of gravity for long periods of time, avoid large doses of radiation, contend with

look at choice E. if you think choice E is correct, then there is tense problem with choice E
the travellers to the Mars avoid, contend and ward off.

this simple tense is used wrongly . present simple is about a condition which, we think, exists indefintely. so, choice E mean that indefintely, the traveller avoid, contend and ward off. this is wrong.

the use of present tense is not hard but not easy. what condition exist indefintely? it is scientific rules. it is what , we think , exist indefintely." she is beautiful" is correct if we think at the moment of speaking, the beauty exist indefintely . though beauty dose not exist forever, but at the moment of speaking, we think the beauty exist indefintely.

Hello egmat

Could you please explain how come there is no verb in option D as pointed out by earlier explanations.

Travelers from Earth to Mars, having to endure low levels of gravity for long periods of time, avoid large doses of radiation, plus contend with the chemically reactive Martian soil, and perhaps even ward off contamination by Martian life-forms.

Can't the above highlighted act as verb for Travelers? if having to endure low levels of gravity for long periods of time act as modifier.
I mean I know that in this way sentence will have different meaning than the original one and will be wrong.

Hi nitinaroraaa , you tagged egmat about the verb issue, but this part needs addressing.

The highlighted sentence keeps appearing in one form or another.

I do not know from what source this belief comes, but the belief is pervasive and causes too many people to avoid correct answers.

Option A does not determine the original meaning.
Use all five options to determine meaning.

Many problems in the official guides contain a choice (A) that could not be and is not the intended meaning of the sentence.

I will give you four examples that I found quickly (read: there may be better examples, but these will suffice).

The questions I mention below can be found from this directory page.
Click on the title that I reference.
On the new page, find the question number.
When you click on the link, the question's topic thread opens.

In OG 2018, look at SC #741 (in which A's meaning is nonsensical and opposite from that intended)
and at SC #781 (in which option A's logic is both incredibly confusing and not the intended meaning)
HERE is yet another example.

If you have access to the Official Guide Verbal Review 2019, look at SC #273, in which the author of the OE writes,
"It is difficult to tell which parts of this sentence go together because of errors and confusion in [Option A]."

Spoiler alert, one incorrect answer to official question revealed:
About the correct answer, which is NOT A, the author writes, "In this sentence, the meaning is clearer . . ."
Part of that OE is here.


In short, we use context, grammar, comparison of options, logic, and other things to discern the intended meaning.
Sure, if option A is garbled and illogical, we can try to infer the meaning from the errors.

On the other hand, we could read the other options and find one that is not garbled and illogical.

I would hate for anyone to eliminate a correct answer because its meaning was different from that in A.
It's okay if the correct answer does not match the meaning in option A.
