For Each of the Following Pairs of Causal Arguments, Determine

For each of the following pairs of causal arguments, determine which is stronger
-Which causal argument is stronger?

A) The swim team had better overall results in their last meet. It seems likely that the reason for the good performance was taking a day off from practice right before the meet. This was the only difference between their practice sessions for this meet and other meets-they maintained the same practice schedule every other day in the week. Thus, taking a day off before the meet must have caused the improved swim team performance.
