(1 point)
time spent exercising and weight loss
sun exposure and ice cream sales

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 changes in the amount of time spent exercising can directly influence weight loss, allowing for a more straightforward assessment of causal relationships through controlled experimentation.
