2. What career will you pursue? (The adolescent will begin stressing about his or her future.)
3. Why is this happening? (Crises are bad no matter the situation, so chances are, we would ask ourselves why this is happening and re-trace the steps.)
I managed to find the complete exercise on the Internet, given that you haven't provided us with all options given to you. 1. cogitating = contemplatingTo cogitate means to think about something (cogito in Latin literally means 'to think). Contemplating means to mull over a couple (or a lot) of options which is what Mr. Gamefield is doing in the excerpt above - he is thinking of ways to pay his rent.
2. cudgeling = beatingA cudgel is a short stick which you can use as a weapon. So if you cudgel something or someone, it means that you are beating them with a cudgel, because it is a thick stick, almost like a bat. So this person was metaphorically cudgeling his brain, but literally cudgeling his donkey.
3. regaled = rewardedThe verb to regale has two meanings - it can either mean 'to entertain someone,' or it can mean 'to supply someone with something.' Here, the latter meaning is used - the donkey thought he would be given a cabbage-stalk or two for his hard work
