Direct Answer :
If Mrs. Clark decides to watch a movie for two hours but could have finished test grading in those two hours, the test grading -- or the opportunity cost of this decision to watch a movie -- is the converse of her action.
Reason :
As we know that Mrs Clark thought of watching a movie that is two hpurs but during the same time, she could have finished the test grading. Tgere are two opportunities here- watch a movie or do test grade. As she should do the test grading, which is more important but watched a movie, her action got reversed.
Conclusion :
Therefore, we can say that the answer is converse.
Hope this helps!
