Question

Read the following prompt:

Compare and contrast the use of mice and chimpanzees in medical research.

Which is the best evaluative thesis for the prompt?


Mice and chimpanzees are both useful for scientific research, but using chimpanzees should be banned.


Chimps are more closely related to humans than mice, while mice can be studied over many generations, which must be considered when designing research.


Neither mice nor chimp studies eliminate the need for drug trials on humans.


Chimps and monkeys both make useful test subjects, but for very different reasons.

Answer 1

Option 1 is best: "Mice and chimpanzees are both useful for scientific research, but using chimpanzees should be banned."

Why: the prompt asks for a compare-and-contrast with evaluation. Option 1 both compares (acknowledges usefulness of each) and makes a clear evaluative claim (chimpanzee use should be banned), which sets up a paper that can weigh scientific benefits against ethical concerns.

Why the others are weaker:
- Option 2 is descriptive (states differences) but not evaluative.
- Option 3 is evaluative but doesn’t compare mice vs. chimps.
- Option 4 misstates the comparison (mentions monkeys rather than mice) and is off-topic.
