Q33:
Which of the following, if true, most logically completes the passage?
A recent poll found that over 80 percent of the residents of Nalmed Province favored a
massive expansion of the commuter rail system as a means of significantly easing
congestion on the province’s highways and were willing to help pay for the expansion
through an increase in their taxes. Nevertheless, the poll results indicate that expansion

easing congestion, because _______.
A. most people in favor of expanding the rail system reported less congestion during
their highway commute as the primary benefit they would experience
B. of the less than 20 percent of residents not counted as favoring the expansion,
about half claimed to have no opinion one way or the other
C. the twice-daily periods of peak congestion caused by people commuting in cars
have grown from about an hour each to almost two and a half hours each in the
past 20 years
D. expanding the commuter rail system will require the construction of dozens of
miles of new railbed
E. the proposed expansion to the commuter rail system will make it possible for
some people who both live and work at suburban locations to commute by rail

Q40:
For most people, the left half of the brain controls linguistic capabilities, but some people
have their language centers in the right half. When a language center of the brain is
damaged, for example by a stroke, linguistic capabilities are impaired in some way.
Therefore, people who have suffered a serious stroke on the left side of the brain without
suffering any such impairment must have their language centers in the right half.
Which of the following is an assumption on which the reasoning in the argument above
depends?
A. No part of a person’s brain that is damaged by a stroke ever recovers.
B. Impairment of linguistic capabilities does not occur in people who have not
suffered any damage to any language center of the brain.
C. Strokes tend to impair linguistic capabilities more severely than does any other
cause of damage to language centers in the brain.
D. If there are language centers on the left side of the brain, any serious stroke
affecting that side of the brain damages at least one of them.
E. It is impossible to determine which side of the brain contains a person’s language
centers if the person has not suffered damage to either side of the brain.
