Many people who want to quit smoking use the nicotine skin patch Nicoband, a prescription medication that delivers nicotine through the skin. Beginning next month, Nicoband will be sold only as a nonprescription medication, whereas the current leading brand of patch will remain available by prescription only. Since as a nonprescription medication Nicoband will be priced significantly lower than comparable prescription medications, its new nonprescription status should help Nicoband become the leading brand.
The conclusion of the argument is the following:
its (Nicoband's) new nonprescription status should help Nicoband become the leading brand
The support for the conclusion is the following:
Beginning next month, Nicoband will be sold only as a nonprescription medication, whereas the current leading brand of patch will remain available by prescription only.
and
as a nonprescription medication Nicoband will be priced significantly lower than comparable prescription medications
The reasoning is basically that being nonprescription will result in Nicoband being less expensive than alternatives and therefore will help Nicoband become the leading brand.
Which of the following, if true, most seriously weakens the argument given?
The correct answer will show that, even though Nicoband will be less expensive than alternatives, it may not become the leading brand.
A. Nicotine skin patches generally cost more to use than do other types of aids that help people to quit smoking.
This choice misses the point and weakens the case for the wrong conclusion.
After all, the conclusion is not that Nicoband will outsell "other types of aids." It's that Nicoband's nonprescription status should help it become the leading brand of patch.
Eliminate.
B. Many insurance plans reimburse people for part or all of the cost of prescription medications, but few do so for nonprescription medications.
This choice weakens the argument by bringing up a factor that could work against Nicoband becoming the leading brand.
After all, if what this choice says is true, then Nicoband's becoming nonprescription may effectively make it more expensive than prescription brands, or at least will likely offset some of the price decrease that comes with becoming nonprescription.
After all, if what this choice says is true, the it's likely that people who buy prescription brands will be reimbursed for part or all of the cost whereas people who buy Nicoband won't be reimbursed.
So, this choice provides information that casts doubt on the conclusion.
Keep.
C. Certain prescription medications should not be taken while a nicotine skin patch is being worn.
This choice has no effect on the argument.
After all, the fact that certain medications should not be taken while a nicontine patch is worn doesn't indicate anything about which patch will be the leading brand.
Eliminate.
D. People who use the Nicoband skin patch have approximately the same rate of success in quitting smoking as do people who use the leading brand of nicotine skin patch.
This choice strengthens rather than weakens the argument.
After all, the fact that Nicoband works just as well as the leading patch is just another reason to believe that Nicoband can become the leading patch with the help of its lower price.
Eliminate.
E. There are fewer restrictions on the advertising of nonprescription medications than on the advertising of prescription medications.
This choice strengthens rather than weakens the argument.
After all, if this choice is true, then Nicoband's nonprescription status will allow less restricted advertising of Nicoband, which could help it become the leading brand.
Eliminate.
Correct answer: B
