Question

1. what must scientists do if a large number of tests refute their hypothesis? a. repeat each test b. publish a report c. reject the test results d. reject the hypothesis

Explanation:

In the scientific method, if a hypothesis is refuted by multiple tests, scientists should reject the hypothesis (since the hypothesis is a proposed explanation, and consistent refutation means it's not supported). Repeating tests (A) isn't necessary if many tests already refute it. Publishing a report (B) without addressing the refuted hypothesis is not scientific. Rejecting test results (C) goes against scientific integrity as test results are evidence.

Answer:

D. reject the hypothesis
