You are correct: the statement in question is a premise for the "ill-advised" sentence, which is the main conclusion.
But, as the previous poster was saying, there is such a thing as an "intermediate/subsidiary" conclusion.
We'll call it IC for short.
You could call an IC a premise, because it DOES provide support for the main conclusion.
But it's also appropriate to call an IC a conclusion, because it has its own supporting idea.
When arguments have an IC, you think of the structure like this:
Main Conc:
Getting to law school is hard
(why?)
Intermed. Conc:
(because ...) Getting a good LSAT score is very difficult.
(why?)
Premise:
(because ...) The LSAT is full of challenging vocabulary and strange logic games.
So the structure of this argument goes like:
Main Conc:
Allowing cell phones on planes would be ill-advised
(why?)
Intermed. Conc:
(because ...) Cell-phones on planes would be even more upsetting than cell-phones on trains or buses.
(why?)
Premise:
(because ...) Planes are packed more tightly than trains or buses, so you can't move around if some cell-phone user nearby is annoying you.
So if you re-read (D), it is just showing this structure:
Prem --> Intermed. Conc --> Conc
The statement in question is an Intermediate conclusion; there is a premise that supports the IC, and the IC supports the Main Conclusion.
== other answers ==
(A) The main conclusion is the 2nd sentence
(B) This claim supports the main conclusion, so the argument is NOT trying to rebut (or go against) it.
(C) This claim DIRECTLY supports the main conclusion, and it does NOT support some other premise. (Some other premise supports IT)
(E) This is not neutral information; it supports the main conclusion.
Hope this helps.
