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:

Since humans have a long reproduction and development time, testing the hypothesis directly on humans over a very long time is impractical, and changing human reproduction speed is unethical and not feasible. Giving up is not scientific. So the scientist should develop new methods (like using animal models, cell cultures, etc.) to test the hypothesis about gene therapy for the genetic disease.

Answer:

C. develop new methods to test the hypothesis.
