(a)
The shortest possible time in which George or complete his activities and a way in which he can order them and complete them in this time.
George has to do four things before his mathematics exam tomorrow morning. Study, sleep, eat pizza, and check his e-mail. He intends to spend two different periods of time studying, 3 hours on each occasion. While the sessions could be back to back, at least one session must occur before he sleeps. Eating pizza requires 1 hour, but it also takes 1 hour for the order to arrive (and something else could be done during this interval). Eating pizza must precede sleeping and also at least one of the study sessions. George will get 6 hours of sleep if he sleep after all study has been completed, but he is willing u settle for 5 hours otherwise. If George checks his e-mail between study sessions. He will do so quickly and tale only 1 hour, otherwise, he will spend 2 hours at this activity.

(c)
The reason if we assume that George decides to read his e-mail before eating his pizza.
