958 - Logical Reasoning

Question1 : A program instituted in a particular state allows parents to prepay their children's future college tuition at current rates. The program then pays the tuition annually for the child at any of the state's public colleges in which the child enrolls. Parents should participate in the program as a means of decreasing the cost for their children's college education.
Which of the following, if true, is the most appropriate reason for parents not to participate in the program?

1. The parents are unsure about which pubic college in the state the child will attend.
2. The amount of money accumulated by putting the prepayment funds in an interest-bearing account today will be greater than the total cost of tuition for any of the pubic colleges when the child enrolls.
3. The annual cost of tuition at the state's pubic colleges is expected to increase at a faster rate than the annual increase in the cost of living
4. Some of the state's public colleges are contemplating large increases in tuition next year.
5. The prepayment plan would not cover the cost of room and board at any of the state's public colleges.
