A new medication for migraine seems effective, but there is concern that the medication might exacerbate heart disease. If patients with heart disease take the medication under careful medical supervision, however, harmful side effects can definitely be averted. The concern about those side effects is thus unfounded.

The argument depends on which one of the following assumptions?

(A) The new medication actually is effective when taken by patients with heart disease.

(B) No migraine sufferers with heart disease will take the new medication except under careful medical supervision.

(C) Most migraine sufferers who have taken the new medication in trials also had heart disease.

(D) The new medication has various other side effects, but none as serious as that of exacerbating heart disease.

(E) The new medication will displace all migraine medications currently being used.

Premises (In logical chronological order)
1) New medication for migraine seems effectvie <-- not effective, but seems to be
2) Concern about new medication is it might exacerbate heart disease <-- use of 'might' (maybe)
3) Concer about side effects is unfounded
4) If patients with heart disease take medication under medical supervision ---> then side effects can be averted (conclusion)

If A then B, If Non B, then non A

We want an assumption to hold up the conclusion.

The argument depends on which one of the following assumptions?

(A) The new medication actually is effective when taken by patients with heart disease.
- Doesn't help. In fact refutes the premise given in the passage. A is out.

(B) No migraine sufferers with heart disease will take the new medication except under careful medical supervision.
- Non A doesn't mean Non B. So this is out.

(C) Most migraine sufferers who have taken the new medication in trials also had heart disease.
- This most supports the conclusion that taking the medication under supervision (trials) can avert the side effects

(D) The new medication has various other side effects, but none as serious as that of exacerbating heart disease.
- Doesn't help

(E) The new medication will displace all migraine medications currently being used.
- Still doesn't tell us how medical supervision can avert side effects

C it is

The link is from the fact that side effect can be eliminated if under close supervision to the conclusion that all side effects do not need to be worried.

The assumption that is needed to arrive that conclusion is that everybody that might suffer from the side effect would be under close supervision.

B should be the answer. I did not read the choice clearly enough to see the word 'except' which holds the conclusion up very strongly.

In (B), No migraine sufferers with heart disease will take the new medication except under careful medical supervision.

Clear B. It fills up the logic gap between the premise and the conclusion.

Conclusion: If new medication is taken under supervision, it is not a concern anymore

This states that if every sufferer with heart disesse take under medical supervision, no concern will be there.

I go with B
