Some people believe that good health is due to luck. However, studies from many countries indicate a strong correlation between good health and high educational levels. Thus research supports the view that good health is largely the result of making informed lifestyle choices.
The reasoning in the argument is most vulnerable to criticism on the grounds that the argumentThe argument says studies show a strong correlation between education and good health, so this supports the view that good health is largely caused by making
informed lifestyle choices.
The argument is treating a correlation as evidence of a causal story: more education leads to more informed choices, which leads to better health. For that to be convincing, it has to rule out other explanations for why education and health move together.
A. Presumes, without providing justification, that only highly educated people make informed lifestyle choices
The argument does not need “only.” It can say education tends to increase informed choices without claiming less educated people never make them. So this is not the main vulnerability.
B. Overlooks the possibility that people who make informed lifestyle choices may nonetheless suffer from inherited diseases
That just says informed choices do not guarantee perfect health. The conclusion says “largely” and can still allow exceptions, so this does not attack the core reasoning.
C. Presumes, without providing justification, that informed lifestyle choices are available to everyone
Availability to everyone is not required for the argument’s claim. The argument is about what explains the general pattern, not about equal access for every person.
D. Overlooks the possibility that the same thing may causally contribute both to education and to good health
This is the key flaw. A third factor (for example, income, access to healthcare, safer living conditions, etc.) could cause both higher education and better health. If so, the correlation would not show that education driven informed choices are what largely produce good health.
E. Does not acknowledge that some people who fail to make informed lifestyle choices are in good health
Again, exceptions do not break a “largely” claim. This does not target the argument’s main logic gap.
