　　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 visibil-

　　ity 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 pre-

　　scribed 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 tranquil-

　　izers are optimal for women is not known.

　　Questions 3-8

　　A landscape designer has available two trees each of eight different species

　　—linden, maple, pine, quince, redbud, spruce, tupelo, and walnut—from which

　　a selection must be made for planting at two different locations. For planting

　　at each location, the designer will select exactly four trees, representing four

　　different tree species, according to the following conditions:

　　If quince is planted at location 1, spruce cannot be planted at location 2.
