Consider the plight of BOB, a student dealing with the choice of allocating his time between studying Math and Demographics. The situation facing BOB could be represented by which of the following 'grade possibility curves' where we measure grades in Demographics on the horizontal axis and the grades in Math on the vertical axis. Use this diagram to answer the following questions.

1. The decision to lower total time spent studying without any reduction in time spent studying Demographics.

2. The decision to allocate more time to studying and less time to TV.

3. The decision to maintain the time spent studying, but increase the time spent studying math.
