Step 1: Identify the argument and conclusion
- Premise: Many medical students enroll in joint M.D./J.D. programs and earn both medical and law degrees.
- Premise: These students primarily earn their law degrees to protect themselves from malpractice lawsuits.
- Conclusion: These students should still be considered doctors, not lawyers.
Step 2: Identify the assumption
The argument assumes that a person’s primary designation (doctor vs. lawyer) depends on the reason they pursued their degree, rather than simply having the degree. The assumption must support the idea that earning a law degree for reasons other than practicing law means they are not actually lawyers.
Step 3: Evaluate the answer choices
(A) Some joint-degree students become lawyers in unrelated fields, while doctors still use their legal knowledge.
- Irrelevant. This does not support the argument that their primary identity is as doctors.
(B) Some joint-degree students are diligent in their legal studies.
- Irrelevant. The argument does not depend on how hard they study law.
(C) If students focused more on law than medicine, they could be considered lawyers.
- This is a hypothetical scenario, not an assumption that directly supports the argument.
(D) A person cannot be considered a lawyer if they got a law degree for purposes other than practicing law.
- Correct. This directly supports the argument’s reasoning that because these students earned law degrees only to protect themselves, they are not actually lawyers.
(E) Medical students get more practical experience in their field than law students do.
- Irrelevant. The argument does not compare the practical experience of doctors and lawyers.
Conclusion
Answer: D
