explain how you get the correct answer

Answer 1

The pair of variables "time spent exercising and weight loss" could be used in an experiment to reach a cause-and-effect conclusion because it is likely that an increase in the time spent exercising would lead to weight loss. This relationship can be tested and analyzed to determine if there is a causal relationship between the two variables. In contrast, the other pairs of variables do not necessarily have a direct cause-and-effect relationship, making it more difficult to draw a conclusion from an experiment.
