  SECTION 6

  Time –30 minutes

  25 Questions

  1.Joyce: Three years ago the traffic commission modified our town's busiest intersection for better visibility, a commendable effort to cut down on traffic accidents there.

  Gary: Over the past three years there have been more, not fewer, traffic accidents per week at that intersection, so the modification has increased the likelihood of accidents there

  The answer to which of the following questions would be most useful in evaluating Gary's argument?

  (A) What proportion of the town's drivers involved in accidents that occurred prior to the modification suffered personal injury in their accidents?

  (B) How long, on average, had the members of the traffic commission held their offices when the modification was implemented?

  (C) Do a majority of the town's residents approve of the traffic commission's overall performance?

  (D) What measures have nearby towns taken within the last three years in order to improve visibility at dangerous intersections?

  (E) How has the volume of traffic at the town's busiest intersection changed over the last three years?

  2. Women make up the majority of the population in the country, and many of the prescriptions written by doctors for tranquilizers are for women patients. The testing of these drugs for efficacy and the calibration of recommended doses, however, was done only on men. Not even the animals used to test toxicity were female.

  The statements above, if true, best support which of the following as a conclusion?

  (A) Some tranquilizers are more appropriately prescribed for women than for men.

  (B) There have been no reports of negative side effects from prescribed tranquilizers in women

  (C) Tranquilizers are prescribed for patients in some instances when doctors do not feel confident of their diagnoses.

  (D) The toxicity of drugs to women is less than the toxicity of the same drugs to men.

  (E) Whether the recommended dosages of tranquilizers are optimal for women is not known.
