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.
A -> B
Because Newtapes adheres twice as long a the currently used -> it is better
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. (no new info)
(B) Most surgical tape is purchased by hospitals and clinics rather than by individual surgeons. (irrelevant)
(C) The currently used tape’s adhesiveness is more than sufficient to hold wounds closed for ten days. (if the currently used is only needed for ten days and then the having a longer life will not be better as the max requirement is only 10 days)
(D) Neither Newtape nor the currently used tape adheres well to skin that has not been cleaned. (not cleaned -- irrelevant)
(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. (special chemical preparation - irrelevant)
