Question 4

Scientists repeat experiments to check if results are consistent (accuracy) and can be trusted (reliability). Proving someone wrong, getting a desired answer, or publishing more papers are not scientific reasons.

If experiment results don't support the hypothesis, the scientific process involves revising the hypothesis and retesting. Discarding the hypothesis, ignoring results, or calling the experiment useless go against scientific method.

Answer:

To ensure accuracy and reliability
