The only purpose for which a particular type of tape is needed is to hold certain surgical wounds closed for ten days—the maximum time such wounds need tape. Newtape is a new brand of this type of tape. Newtape’s salespeople claim that Newtape will improve healing because Newtape adheres twice as long as the currently used tape does.

Which of the following statements, if true, would most seriously call into question the claim made by Newtape’s salespeople?

(A) Most surgical wounds take about ten days to heal.
(B) Most surgical tape is purchased by hospitals and clinics rather than by individual surgeons.
(C) The currently used tape’s adhesiveness is more than sufficient to hold wounds closed for ten days.
(D) Neither Newtape nor the currently used tape adheres well to skin that has not been cleaned.
(E) Newtape’s adhesion to skin that has been coated with a special chemical preparation is only half as good as the currently used tape’s adhesion to such coated skin.

I am not convinced with the OA. Please comment.

(A) Most surgical wounds take about ten days to heal. >>> Already mentioned in the argument, and it doesn't weaken the conclusion that "Newtape will improve healing"
(B) Most surgical tape is purchased by hospitals and clinics rather than by individual surgeons.>>> out of scope
(C) The currently used tape’s adhesiveness is more than sufficient to hold wounds closed for ten days.>>> The argument made is "Newtape will improve healing" because "Newtape adheres twice as long as the currently used tape does". In short, argument is : Longer the tape sticks, better the tape is..>>> We can weaken the argument if we prove that "the newtape doesn't adheres for long enough"
(D) Neither Newtape nor the currently used tape adheres well to skin that has not been cleaned. >>> Will not affect the comparison between the two tapes
(E) Newtape’s adhesion to skin that has been coated with a special chemical preparation is only half as good as the currently used tape’s adhesion to such coated skin.>>> Correct

Tape is used to hold wounds closed for ten days the maximum time such wounds need tape.

Claim:Newtape will improve healing because Newtape adheres twice as long as the currently used tape does.

How do we weaken this!!!!

because its already mentioned that Max time to hold a wound is 10days. if we can prove that the present tape holds good for 10days, and even though the newtape is capable of holding wound for longer time its of no use.

Option C does it.....
C)The currently used tape’s adhesiveness is more than sufficient to hold wounds closed for ten days.

Ravi,

Does this point weakens the claim made by the Newtape salespeople?
No. I think (C) weakens the need for new tape for surgical purposes by say hospital.

I'd agree with this.

The claim is that it "will prove healing."

Improving healing is based on 1) how long the wound takes to heal and 2) how long the tape holds.
The sentence says that the max healing time is 10 days.

So a) would actually improve the claim because it undermines the "max 10 days" thing, suggesting a potential use for the new tape.
b) As someone said, is out of scope.
d) and e) are referencing situations (clean skin, chemically treated skin) that are not referenced in the opening sentence, and one can assume such situations are irrelevant or redundant (what kind of doctor is going to dress a dirty wound?)

c) doesn't contradict the "max 10 days" and it goes on to state that current tape will hold for 10 days or more, meaning the new tape would act no differently, thereby NOT improving (or deterring) healing.

So by logic AND processes of elimination it's gotta be C.

OA plz.

Note: this cannot be correct since there is no time reference. What if "the currently used tape’s adhesion to such coated skin" is 80 days (the chemical reaction creates a crazy bond)? Then NewTape is 40 days.

One question:
Are the sales ppl saying that the new tape is better than the old tape?

They claim that the new tape will hold on the wound for 20 days, so this will iprove healing. What if, we can show that the new tape is half the adhesive powered as compared to the old tape then the new tape will not hold longer. So, their claim that it will improve the healing will be weaken.

So, E should be the OA.

Meh: "Newtape’s salespeople claim that Newtape will improve healing." Healing is dependent on holding time (max needed - 10 days).

"Better" is sort of implied, but we have to think objectively.

ykaiim wrote:

No, they do not. They say it will hold twice as long. We're never actually given the amount of time that the current tape holds, only the max amount of time required to complete healing.

Sure, but none of the answers given say this. E talks about 'specially treated' skin, and says NewTape is only half as good as current tape, but we're never told what the current tape's performance is on that chemically treated skin (or otherwise, for that matter). Like in my last post, what if it's 80 days? Then NewTape holds for 40 days, both are sufficient for healing.

C is the only answer that gives us the crucial puzzle piece: how long does the current tape hold? (and is it equal to, greater than or less than 10 days?) Turns out it's >10 days, rendering NewTape redundant (and possibly annoying).

The option A is out of scope since nothing about the duration of healing of wounds is mentioned in the argument.
