Question

1. what would be the best search terms to use for a research project about the health benefits of exercise?○ healthy benefits, gym○ healthy, exercise, running○ health benefits, exercise○ running, gym, exercise

Explanation:

The research project focuses on the health benefits of exercise. The best search terms should directly match the core topic: the health outcomes tied to exercise, with no irrelevant or redundant terms. Option 3 uses "healthy" (an adjective, not the core noun phrase "health benefits") and includes "running" which narrows the scope unnecessarily. Option 1 adds "gym" which is a specific setting, not the core topic. Option 4 focuses on exercise types rather than the health benefits. Only option 2 uses the exact core terms: "health benefits" (the focus) and "exercise" (the subject), with no extra, narrowing, or irrelevant terms.

Answer:

health benefits, exercise
