Passage 1

In the 1920s, Gerstmann described a set of problems found in people who have

suffered damage to the brains left parietal lobe, problems that contain being

unable to comprehend arithmetic and having difficulty recognizing ones fingers.

There is still no consensus on whether the symptoms Gerstmann noticed consti-

tute a syndrome, but the parts of the brain used for storing facts about numbers

and for representing the fingers are close to each other. Mental representations

of numbers and of fingers may hence be functionally connected. A 2005 exper-

iment had people perform some tasks requiring dexterity and others including

matching pairs of numbers, while an area of their parietal lobes the left angu-

lar gyrus was stimulated by a magnetic field. Facility at both sets of tasks was

jeopardized.

1. The author of the passage would most likely agree that the highlighted

statement suggests

A. a flaw in the experiment conducted in 2005

B. a means by which dexterity might compensate for a loss of arithmetic ability

C. an explanation for some of Gerstmanns observations

D. an anomaly in some of Gerstmanns results

E. a reason to doubt damage to the left parietal lobe as a causal factor in certain

Symptoms C

2. The author of the passage describes the 2005 experiment and its results

primarily in order to

A. establish the proximity between the part of the brain used for storing nu-

merical information and the part used for representing the fingers

B. illustrate the implications that Gerstmanns work may have for experimental

research

C. cast doubt on the idea that damage to the left parietal lobe causes the set of

problems that Gerstmann described

D. support a hypothesis about a significant association between parts of the

brain related to fingers and to numbers

E. suggest that the problems Gerstmann noted in relation to numbers and fin-

gers have a different cause than the other problems associated with parietal lobe

damage  D
