Summarize Argument
The medical reporter claims that most people in industrialized nations would benefit from taking an aspirin a day. This is because aspirin helps with heart disease, which is common in these nations.
Identify and Describe Flaw
The flaw here amounts to missing the key difference between what’s common and what’s true of most people. Heart disease may be one of the most common illnesses, but that doesn’t mean that the majority of people suffer from it. Since the conclusion is that aspirin will benefit most people in the nation, merely establishing that the illness it treats is common is not enough to justify it.
A
It takes for granted that if medication can reduce the severity of heart disease, it can also prevent some cases of heart disease.
The argument doesn’t claim that aspirin prevents heart disease, just that it improves health. The flaw lies in the presumption that this applies to most people in these nations.
B
It overlooks the possibility that even if a disease is one of the most common in a nation, most people in that nation are not in significant danger of developing that disease.
This describes how the argument fails to justify the claim that aspirin would benefit the majority of people. Simply establishing that the disease it treats is common isn’t enough.
C
It overlooks the possibility that preventing or reducing the severity of heart disease has little or no effect on any of the other most common diseases in industrialized nations.
This is irrelevant. The doctor’s claim is that aspirin helps with heart disease, thereby improving health. It doesn’t matter whether or not it affects other diseases. The flaw is assuming that aspirin would improve health for the majority of people in these countries.
D
It fails to address the possibility that taking an aspirin a day is not the single most effective measure for preventing heart disease.
This is irrelevant because the doctor never claims that it’s the best at preventing the illness, only that it helps. The flaw is assuming that this would be helpful for most people in these countries.
E
It fails to address the possibility that the studies on the beneficial effects of aspirin were conducted only in industrialized nations.
This is irrelevant. There’s no reason to believe that conducting studies in industrialized nations would make their findings less reliable.
