The new drug Prozac and the old one Elavil are about equally effective in treating various forms of depression, although patients on the newer drug may have slightly fewer side effects. Thus, revenue from the sale of the new drug is going to far exceed the revenue from the sale of the old drug.

All of the following statements weaken the conclusion of the argument above, EXCEPT:

(A) Elavil is also used as a powerful anti-emetic medicine.
(B) The Drug Control Authorities in six states have refused to allow the sale of Prozac till some more tests are carried out.
(C) Some side effects of Elavil are common to Prozac as well.
(D) Prozac is not recommended as an anti-depressant for diabetics and heart patients.
(E) The unit sale price of Elavil is higher than that of Prozac.

Am not clear with the explanations provided hence, reopening this post..

IMO . E strengthens the conclusion. C is neutral and the rest weaken, since this is all weaken except question went for the one that strengthens. Please clarify why E os incorrect here

Will vote for C

Question : ALL Weaken : EXCEPT

Conclusion: revenue from sale of new drug(Prozac) exceed revenue from sale of old drug(Elavil)

P1 - both drugs equally effective
P2 - Prozac slightly few side effects

(A) Elavil is also used as a powerful anti-emetic medicine.
--> Weaken the conclucion (Elavil has some additional feature that is important and hence the sale of Elavil can be more - hence more revenue for old drug)

(B) The Drug Control Authorities in six states have refused to allow the sale of Prozac till some more tests are carried out.
--> Clear Weakens the conclusion (Claerly shows the ban on sale = loss of revenue)

(C) Some side effects of Elavil are common to Prozac as well.
--> No effect on conclusion (keep is a side)

(D) Prozac is not recommended as an anti-depressant for diabetics and heart patients.
--> Can weaken the conclusion

(E) The unit sale price of Elavil is higher than that of Prozac.
--> If unit sale price of Elavil is hight we can argue that revenue from Elavil is higher then Prozac
example: Elavil per unit profit might be : $2 compared to Prozac unit profile of 5 cent clearly the revenue from Elvial can be more hence weaken the conclusion

So ans should be C

E involves only assumption, if you assume E can strengthen and if you assume E can weaken. Its not the airtight option. Now surfing through the options C makes more airtight statement how much one assumes C can never weaken. It has already been mentioned in argument that new one has less side effects than older one.
okay suppose 10 and 80 respectively. out of these side effects even if 7-8 are same then that doesnt alters anything in the conclusion. Its basically neutral and hence is the correct airtight option.

The new drug Prozac and the old one Elavil are about equally effective in treating various forms of depression, although patients on the newer drug may have slightly fewer side effects. Thus, revenue from the sale of the new drug is going to far exceed the revenue from the sale of the old drug.

All of the following statements weaken the conclusion of the argument above, EXCEPT:

To weaken the conclusion would be to find reasons why Prozac revenue would be lower or why Elavil revenue would be higher.

(A) Elavil is also used as a powerful anti-emetic medicine. This other use of Elavil might give it an advantage over Prozac and increase its sales.
(B) The Drug Control Authorities in six states have refused to allow the sale of Prozac till some more tests are carried out.
In states where Prozac sales are prohibited, Elavil would be sold.
(C) Some side effects of Elavil are common to Prozac as well. From the stimulus we know that they're similar in efficacy and only differ in side effects. If Elavil's side effects are common to Prozac's, it presents no advantage over Prozac. Moreover, the stimulus says that the side effects of Prozac are fewer, thus giving it a potentially greater advantage over Elavil (strengthening the argument).
(D) Prozac is not recommended as an anti-depressant for diabetics and heart patients. Prozac would be a health hazard for some, thus Elavil would be sold.
(E) The unit sale price of Elavil is higher than that of Prozac. A higher price could generate greater revenue than Prozac.

I have a doubt with C - with the wording and interpretation and would like some help with that. Queries highlighted below:
The new drug Prozac and the old one Elavil are about equally effective in treating various forms of depression, although patients on the newer drug may have slightly fewer side effects. Thus, revenue from the sale of the new drug (PROZAC) is going to far exceed the revenue from the sale of the old drug.

All of the following statements weaken the conclusion of the argument above, EXCEPT:

(A) Elavil is also used as a powerful anti-emetic medicine. - Basically it says Elavil has two uses - so ppl maybe inclined to buy this more/ or is generally irrelevant to increased sale of Prozac. SO it can fall into the 'except' category
(C) Some side effects of Elavil are common to Prozac as well.So it says the side effects are COMMON with Prozac. In argument above it says P will have LESSER side effects. So by reading 'common' it can be that there are an overlap of side effects but are still fewer. Ex. P has 4 side effects and E has 8 but those 4 of P overlap with E. How is this a non - weakener/ irrelevant then?

:( Would like some guidance

I want to discuss so don't just type in your answer (that is why I have provided the OA). Do explain.



can anyone explain which one is better between C and E
