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 s 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.

Please explain the assumption behind it a detailed explanation will be welcome thanks

IMO:C

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

C:The currently used tape's adhesiveness is more than sufficient to hold wounds closed for ten days.

IF currently used tape is sufficient to heal there is no need for newtape..

E:Talks about some other factor which might b helpful ....But that is not what d argument is about..

thx

i will choose C.
i states that adhere of the newtape is redundancy comparing with the old one. while the old one is sufficient for 10 days adherent to wounds.

Please share your idea and your reasoning

IMO E.

C does not weaken the claim that Newtape will improve healing but E does.

It's definitely (c).

Let's look at some key facts from the argument:

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.

(e) is the first time we hear about the special chemical preparation. We have no clue if and when this preparation is used, so (e) must be outside the scope.

Here's an important tip for evaluating choices: if you read a choice and think "well, that would be a good answer if I had another piece of information", if you do NOT have that other piece of information, the choice is outside the scope and is wrong.

Newtape's big selling point is that it lasts twice as long as the currently used tape. However, if (c) is true, then since we know that 10 days is the maximum relevant time, Newtape's claim is worthless.
