LSAT Practice Test

The claim that humans are still biologically adapted to a diet of wild foods plays which one of the following roles in the nutritionist's argument?

1. Counterargument

2. Evidence

3. Conclusion

4. Assumption

The correct answer is: Assumption

In this argument, the claim that humans are still biologically adapted to a diet of wild foods serves as an assumption. The nutritionist assumes that our biological adaptation to a diet of wild foods is relevant to the discussion about modern diets and health. This assumption underlies the nutritionist's recommendation to closely mimic a wild diet in order to improve health. The claim supports the nutritionist's conclusion by providing a foundational belief upon which the argument is built. Option A is incorrect as the claim is not presented as a counterargument, but rather as a foundational belief in support of the nutritionist's recommendation. Option B is also incorrect because while the claim may serve as supporting evidence for the nutritionist's argument, it is more fundamental than just evidence. Option C is incorrect because the claim is not the ultimate conclusion of the argument itself; rather, it is a key assumption leading to the conclusion.
