Megan has a 1 hr gap in her course load for the fall semester. There are two courses available for her to take at that time: reading piano sheet music and beginning rock climbing. She does not have any experience with piano or rock climbing. In the end, she decides to enroll in the rock climbing course, despite her fear of heights. Identify which activity exhibits a potential trade-off with enrolling in rock climbing.

The activity that exhibits a potential trade-off with enrolling in rock climbing is:

reading piano sheet music.

Explanation:

A potential trade-off with enrolling in rock climbing that Megan faces is the next available course, which is the reading of piano sheet music.  She can either enroll in the rock climbing or the reading of piano sheet music.  When she chooses one course, the other course will be left unchosen.  This can be likened to opportunity cost.  But strictly, a trade-off involves all forgone alternatives, while an opportunity cost involves the best alternative.
