Stimulus

That long-term cigarette smoking can lead to health problems including cancer and lung disease is a scientifically well-established fact. Contrary to what many people seem to believe, however, it is not necessary to deny this fact in order to reject the view that tobacco companies should be held either morally or legally believes that candy eaters who get cavities should be able to sue candy manufacturers.

What this question is testing

Main Conclusion

Conclusion

The author wants to make a fairly subtle point: you can fully accept that smoking causes health problems and still reject the idea that tobacco companies are responsible for those problems.

Evidence

The candy analogy does the work. Candy causes cavities — undeniably. But nobody thinks candy makers should be sued by people with cavities. So "X causes Y" doesn't automatically mean "the maker of X should pay for Y."

Evaluate

The main conclusion is the equivalent: causation by smoking isn't enough by itself to justify holding tobacco companies responsible. You need more than causation; the candy case shows why.

Goal

Find the answer that captures: causation alone isn't enough to justify responsibility.

The main point of the argument

Answer choices

  1. Bad Conclusion Match6% picked this

    no one should feel it necessary to deny the scientifically well-established fact that long- term cigarette smoking can

    The author isn't concluding that no one should feel the need to deny the smoking-harm fact. The author is concluding that you don't need to deny it in order to reject company responsibility. This answer drops the "in order to" connection and turns it into a free-standing conclusion about denial. That's not the main point.

  2. Premise0% picked this

    people who get cavities should not be able to sue

    This is the candy half of the analogy — the supporting evidence. The author uses it to draw a parallel with the tobacco case, but it's not the main conclusion. The main conclusion is the parallel claim about tobacco/companies, not the candy claim itself.

  3. Correct92% picked this

    the fact that smokers’ health problems can be caused by their smoking is not enough to justify holding tobacco companies either legally

    Why this is right

    This is the main conclusion. The author's point is that the causal fact (smoking → poor health) isn't enough by itself to justify holding tobacco companies responsible. The candy analogy demonstrates the same logic: candy causes cavities, but that fact alone doesn't justify suing candy makers. So the equivalent claim about tobacco companies — "smoking-causes-harm isn't enough to justify responsibility" — is what the argument is establishing.

    Skill tested: Main Conclusion · how this choice captures the argument's function is the move to repeat next time.

  4. Unsupported0% picked this

    excessive consumption of candy will lead to health problems just as surely as long-term

    The author doesn't claim candy and smoking lead to comparable health problems. The candy comparison is structural, not about magnitude — both have known causal links. Whether candy's effects are as severe as smoking's isn't something the author asserts.

  5. Unsupported2% picked this

    if candy manufacturers were held responsible for tooth decay among candy eaters then tobacco companies should also be held responsible for

    The author isn't making a conditional claim about what would follow if candy makers were held responsible. The author uses the candy case as evidence that we don't hold makers responsible for causation. The author isn't saying "if we did hold them responsible, then we'd have to hold tobacco responsible too" — that flips the argument.
