[cesar.rodriguez.blanco]

I do not understand what is the difference between B and D.
OA is D.

Unlike the short flights of the shuttle and earlier spacecraft, which carried sufficient power in fuel cells and batteries, a permanently orbiting space station will have to generate its own electricity.

A: the short flights of the shuttle and earlier spacecraft, which carried sufficient power in fuel cells and batteries
B: the shuttle and earlier spacecraft, with sufficient enough power in fuel cells and batteries for their short flights
C: the short flights of the shuttle and earlier spacecraft, which enabled them to carry sufficient enough power in fuel cells and batteries
D: the shuttle and earlier spacecraft, which were capable of carrying sufficient power in fuel cells and batteries for their short flights
E: the flights of the shuttle and earlier spacecraft, whose shortness allowed them to carry sufficient power in fuel cells and batteri

Sufficient - enough : more or less same meaning in B.

[cesar.rodriguez.blanco]

What do you mean?

[sunny.jain]

either you need Sufficient fuel for
Or you need enough fuel for their flight.

Using together "sufficient + enough" is not good way.

just for your knowledge, MGMAT test a lot about "enough"

Enough has two possible idiom:
enough to
enough for

Water was hot enough to boil the vegetables.
water was hot enough for me to boil the vegetables.

Use:
X enough to Y
More emphasis on Y.

yes. great.

two things to add:

(1) sufficient + enough is REDUNDANT. redundancy is very bad.
same reason you wouldn't say "reply back", "added bonus", or "determined as a result of" (see #138 in OG11, if you have that).

(2) make sure you know that "enough THAT" is incorrect.
the 2 idioms mentioned above are correct.

Hi guys,

I understand that in B) sufficient and enough are redundant. However, I believe that even if we delete either one, choice D) is still better than choice E) for the following reason:

With sufficient enough power in the fuel cells... can be either an adjectival or an adverbial phrase, so it is not clear that which part of the sentence this phrase modifies. If it modifies the first part of the sentence, Unlike the shuttle and earlier spacecraft, it will function as an adjectival phrase, but if it modifies the last part of the sentence, a permanently orbiting space..., it will function as an adverbial phrase. Thus this phrase causes ambiguity, so it is bad.

Can anyone comment on my reasoning? Thank you very much!

the sentence begins with "Unlike"..it means that you are comparing 2 things ..Look the starting of the not underlined part following the underlined part ...The sentence is trying to compare " space station" in the later part of the sentence to something in the beginning of the sentence...It has to be "shuttle and earlier spacecraft" and not the "flights"

To me , the only contenders were B and D ... D is correct

[mschwrtz]

That's exactly right.

The most common use of like/unlike is just this one.

Like/Unlike X, Y predicate.

In the OA, the X is "the shuttle and... spacecraft," the Y is "a... space station," and the predicate is "will have to...."

Of course, the GMAT confuses your ear by modifying X, thereby putting stuff between X and Y. In this case the modifier is "which carried sufficient power in fuel cells and batteries."

Hi Ron,

I have the same question here? Is that will be a correct answer if "enough" in B is removed? is "with..." here a absolute phrase? I'm pretty confused with the usage of with in GMAT. Please help! Thanks a lot!

Here's what such a sentence would look like,

Unlike the short flights of the shuttle and earlier spacecraft, with sufficient power in fuel cells and batteries for their short flights , a permanently orbiting space station will have to generate its own electricity.

You are certainly correct that such a sentence would be incorrect. Remember that this sort of ambiguity is actually pretty rare on the GMAT, and usually presents as a split between noun phrase (e.g. those companies) and pronouns (e.g. them).

Can "comma +with" structure be used both as " adj modifier" and "adv modifier"?
All I know is that "comma+with" sturcture is only used as "adv modifier"-to modify the verb.
EX: Jim walked in the park, with smile on his face.
Can someone confirm on this point and give some examples for "with" structure used as "adj modifier"?

Your reasoning above is sound. Because you want adj modifiers next to the noun they modify, you wouldn't use a comma before the with. In adv modifiers, you need a comma to express that it's modifying something that's often times farther away in the sentence and helps to clarify what you are modifying.

With style, the hat fell to the ground.

Please let me know why the sentence in italics is grammatically incorrect.
