OFFICIAL SOLUTIONThe argument draws parallels between the medieval and modern times and concludes that the dynastic system of sons taking on their fathers’ jobs has not changed over the years. To make the point, the author gives an example of blacksmiths in medieval times and baseball players today. In order to question the credibility of the argument, the correct option must point out that the times are different and that there need not be a parallel between career systems today and in medieval times.
Option (A) gives one more example of dynastic systems today. If anything, (A) lending further credibility to the argument and is not refuting it. For the same reason,
Option (D) can also be eliminated.
Option (C) implies that having a father in the same profession increases the possibility of the son following the father’s footsteps. The reasoning and implication in (C) is probably not as evident as in (A) and (D) but ultimately, (C) lends credibility to the argument, if anything.
Option (E) is possibly a very attractive option. However, the argument does not state that genetic makeup was the reason that people chose a profession; rather it was the accepted practice of the day. Therefore, stating that genetic makeup does not influence the success of a career is irrelevant to the argument. Also, the argument does not discuss “success” in a career at all but just the choice of a career.
Option (B) works because it implies that there was no choice given to those who lived in mediaeval times. The argument, when discussing the “likelihood” of someone becoming a baseball player implies that anyone today has the choice to become one, if they wanted to. Thus, a difference in the systems today and then has been pointed out and the option weakens the author’s reasoning.
