It is truly a waste of time to attend college. Out of the ten richest people in the world, six are college dropouts. Thus, if one wants to become rich, then it makes sense to drop out of college and start one’s own venture.
Which of the following, if true, casts the most serious doubt on the argument?
(A) Had the six people mentioned in the argument attended college, they may have been even richer than they are currently.
(B) Attending college helps a person increase his or her social circle by making new friends.
(C) Statistics reveal that 95% of all new ventures are most likely to fail.
(D) The percentage of college dropouts who have gone on to become rich is several times smaller than the percentage of college graduates who have gone on to become rich.
(E) Becoming rich is not the only measure of success, happiness is perhaps more important.
Out of 10 richest people 6 are college dropouts who went on to start a venture. So to become rich, one should dropout of college.
