A recent report determined that
although only three percent of drivers on Maryland highways equipped their
vehicles with radar detectors, thirty-three percent of all vehicles ticketed
for exceeding the speed limit were equipped with them.  Clearly, drivers who equip their vehicles
with radar detectors are more likely to exceed the speed limit regularly than
are drivers who do not.

The conclusion drawn above depends
on which of the following assumptions?

(A) Drivers who equip their
vehicles with radar detectors are less likely to be ticketed for exceeding the
speed limit than are drivers who do not.

(B) Drivers who are ticketed for
exceeding the speed limit are more likely to exceed the speed limit regularly
than are drivers who are not ticketed.

(C) The number of vehicles that
were ticketed for exceeding the speed limit was greater than the number of
vehicles that were equipped with radar detectors.

(D) Many of the vehicles that were
ticketed for exceeding the speed limit were ticketed more than once in the time
period covered by the report.

(E) Drivers on Maryland highways
exceeded the speed limit more often than did drivers on other state highways
not covered in the report.

Hutonian Government Official:  Federal law requires truck drivers to take a
long break after driving for ten hours, but truck drivers frequently do not
comply.  Since the public rest areas
along our highways cannot accommodate all the drivers needing a break, we plan
to build more rest areas to increase the rate of compliance.

Hutonian Business
Representative:  But if the parking lots
around our businesses are considered, there are more than enough parking
places.

Which of the following, if true
about Hutonia, would provide a reason for persisting with the government
official's plan despite the objection?

(A) Public parking areas are evenly
distributed along the highways.

(B) Truck drivers are most likely
not to comply with the federal law if the total time required for a trip
exceeds ten hours by less than an hour.

(C) In comparison to public rest
areas, private parking lots near highways tend to be time-consuming for drivers
to reach.

(D) Even when rest areas are
available, some truck drivers park in places, such as highway access ramps,
where their trucks are likely to cause accidents.

(E) Some public parking areas,
particularly those on heavily traveled roads, are substantially larger than
others.
