question 8 of 10
only an experiment can show:

a. how children develop over time.

b. how one thing causes another.

c. what a large number of people believe.

d. how people act in a natural environment.

Explanation:

• Option A: Studying children's development over time is often done through longitudinal studies (not just experiments).
• Option B: Experiments are designed to establish causal relationships by manipulating an independent variable and observing its effect on a dependent variable, allowing determination of how one thing causes another.
• Option C: To find out what a large number of people believe, surveys or polls are more appropriate, not experiments.
• Option D: Observing how people act in a natural environment is typically done through naturalistic observation, not experiments.
