Television, which made its first serious appearance in 1939, did not become common until the early 1950s. Since then. millions of children have grown up in front of the set, and many people now worry about the effect that TV has on the young, and on society in general. Many ordinary parents wish it had never been invented.

[单项选择]
Mr. Faugel was convinced that student nervousness had affected their scores; to reduce the anxiety of these students who had already been tested, he gave 22 of them a beta blocker before readministration of the test. Their scores improved significantly. The other 8 students (who did not receive the beta blockers) improved only slightly. Second-time test-takers nationwide had average improvements which were similar to those in Faugel’’s non-beta blocker group. Beta blockers are prescription drugs which have been around for 25 years. These medications, which interfere with the effects of adrenalin, have been used for heart conditions and for minor stress such as stage fright. Now they are used for test anxiety. These drugs seem to help test-takers who have low scores because of test fright, but not those who do not know the material. Since there can be side effects from these beta blockers, physicians are not ready to prescribe them routinely for all test-takers.
F
A. increased scores less than the national average
B. increased scores the same as the national average
C. decreased scores
D. increased scores much more than the national average
