Answer 1

The pair of variables that could be used in an experiment to reach a cause-and-effect conclusion is time spent exercising and weight loss.

In this case, you can manipulate (or measure) the amount of time spent exercising to observe its effect on weight loss, which allows for a potential cause-and-effect relationship to be analyzed. The other pairs listed may show correlation but do not allow for clear experimental manipulation to establish direct causation.
