59. Chapter ma2pe08r, Section .11, Problem 069 (ID: 069.01.1 - MC - MANK08) College-age athletes who drop out of college to play professional sports a. are not rational decision makers. b. are well aware that their opportunity cost of attending college is very high. c. are concerned more about present circumstances than their future. d. underestimate the value of a college education.

b. are well aware that their opportunity cost of attending college is very high.

Explanation:

Since the College-age athletes are able to play professional sports; (which is one of the things an athlete longs for in his career) without finishing college. Going back to college would seem like a waste of time to them because they have achieved a milestone even without finishing college.

Hence, they are well aware that their opportunity cost of attending college is very high.

B) are well aware that their opportunity cost of attending college is very high.

Explanation:

Opportunity costs refer to the extra costs or benefits lost from choosing one activity or investment over another alternative.

When we are talking about college athletes, that might mean a lot of money, since staying at college means that they will not be able to play professionally. Professional sports leagues use rookie contracts which are generally "cheap" to try to discourage college students form dropping out, but still those cheap contracts have 5 zeros.  

Many players are concerned about their careers being too short and others are simply eager to become rich. So many decide to drop out of college and enter the draft.
