Question

which of the following describes a reason for making a prediction when doing a controlled experiment?
a. to indicate what specific results will support a hypothesis
b. to provide a context for why a specific question was asked
c. to understand the nature of an experimental subject
d. to identify a useful and reliable source of scientific information

Explanation:

In a controlled experiment, a prediction (often from a hypothesis) outlines what results would support the hypothesis. Option A matches this: predictions help define what outcomes validate the hypothesis. Option B is about context for the question (not prediction’s role). Option C is about understanding the subject (not prediction’s purpose). Option D is about identifying info sources (unrelated to prediction in experiments).

Answer:

A. To indicate what specific results will support a hypothesis
