sure, those things can have capabilities.

you just have to ask yourself: "To whom, or to what, to these "capabilities" belong?"
this could very reasonably be a person, an animal, OR an inanimate object.

Wow, I am sorry for that.
Thanks for your excellent explanation!

Hi instructors,

I read a comment in other forums which said-
Other than redundancy, B is also wrong because the position of " with sufficient enough power in fuel cells and batteries for their short flights" leads to ambiguity.
Because "with xxxx" then could be modifying either the shuttle and earlier spacecraft or a permanently orbiting space station

Is that ambiguity a solid ground to eliminate this choice?
Thank you in advance.

[RonPurewal]

^^ no, the meaning of that modifier is obvious enough.

Ron, does "comma with..." in answer choice B is an issue? Is it correct? Tks!

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.

[Sage Pearce-Higgins]

The construction ", with" is not a wrong one (you can find lots of SC questions from the OG that use it correctly), but in answer B it's an incorrect modifier, as the sentence doesn't make clear what it is that has sufficient power.
