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**

This is because you can manipulate the independent variable (time spent exercising) and observe the effect on the dependent variable (weight loss), allowing for a clearer determination of a causal relationship.
