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?

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?

the following as a conclusion?

scribed for women than for men.

izers are optimal for women is not known.
