Option A-Most surgical wounds take about ten days to heal.
If surgical wounds take 10 days to heal, then whether someone uses Newtape or old, it doesn't matter.
Thus Newtape’s salespeople claim that Newtape will improve healing is wrong.
Option 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.
Why Salespeople made the claim at firstplace ? because they believe Newtape adheres twice as long as the currently used tape does.
But now option E weaken that reason.
Hence E can be correct.
Experts Please explain.
Hello again,
Harsh2111s. The key here is to appreciate that the exact claim says
that Newtape will improve healing because Newtape adheres twice as long as the currently used tape does. Choice (A) does not address tape (in a tape-to-tape comparison) in any way, and what does
about ten days mean anyway? Does that mean 8-12 days? 9-11? Does it mean that Newtape number-crunchers took the available data of the healing times of all surgical patients treated with
the currently used tape and averaged the figures out to arrive at
about ten days? In either scenario, the claim could hold. Choice (A) is gone.
Meanwhile, choice (E) introduces a complete distraction in this
special chemical preparation. Does the passage mention that post-op treatment of surgical incisions involves dressing the skin with this chemical preparation? No. It is only your mind trying to come up with a reasonable assumption—something that can get you into trouble on CR questions in general. If you want to get to the heart of the matter, you have to stick with what the passage tells you. In choice (C), notice the qualifier
more than sufficient. If the current tape is more than sufficient for its purpose
over the ten-day period in question, the very ten-day period that the passage marks as
the maximum time [surgical] wounds need tape, then a tape that lasts longer is no better for its intended purpose. It will
not improve healing any more on the basis of its adhesive longevity.
I hope that helps. If you have further questions, feel free to ask.
