Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

         Mr. Faugel was convinced that students’ 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.

The word “reduce” in paragraph 1 most nearly means ________.

A. build up           

B. lessen      

C. increase  

D. maximize

Đáp án D

Theo như đoạn văn, ____________

A. mọi người đều có thể dùng thuốc chẹn Beta.

B. thuốc chẹn Beta được kê đơn rộng rãi.

C. thuốc chẹn Beta chỉ giúp cải thiện điểm nếu thí sinh thực sự có kiến thức.

D. thuốc chẹn Beta chỉ giúp giảm căng thẳng thi cử.

“These drugs seem to help test-takers who have low scores because of test fright, but not those who do not know the material.”

(Những thuốc này chỉ có tác dụng với những ai điểm thấp do căng thẳng mà không có tác dụng cho những ai không có kiến thức)

Từ bài đọc, ta biết thuốc này chỉ được dùng với đơn thuốc của bác sĩ mà không dùng tùy tiện, và các bác sĩ không kê đơn rộng rãi loại này do chúng có tác dụng phụ, và loại thuốc này không chỉ có tác dụng giảm căng thẳng thi cử mà còn giúp điều hòa nhịp tim, giảm áp lực nhẹ,... nên A, B, D là sai.
