Question

a scientist wants to examine a genetic disease in humans. the scientist hypothesizes that the disease can be treated by using gene therapy. humans take a long time to reproduce and develop, so the scientist will have to
○ give up on testing the hypothesis.
○ test the hypothesis for a very long time.
○ develop new methods to test the hypothesis.
○ find a way to make humans reproduce faster.

Explanation:

The problem is about a scientist testing a hypothesis related to a genetic disease. Since humans have long reproduction/development times, giving up (first option) is not scientific. Testing for a very long time (second option) is impractical. Making humans reproduce faster (fourth option) is unethical and not feasible. So, the scientist should develop new methods (like using model organisms, cell cultures, etc.) to test the hypothesis, which matches the third option.

Answer:

C. develop new methods to test the hypothesis.
