[問題]大全D-4

In 1981, for the first time in over two decades, the average scores of high school students on standardized math and English tests did not decline. During the same year, millions of American students enjoyed their first exposure to the new world of the microcomputer, whether in schools, video arcades, or other settings. The conclusion is clear: far from stultifying the intellectual capacities of students, exposure to computers can actually enhance them.
The most serious weakness of the argument above is its failure to
(A) discuss the underlying causes of the twenty-year decline in students’ test scores
(B) cite specific figures documenting the increases in test scores
(C) distinguish among the various types of computer being used by high school students
(D) define the intellectual capacities tested by the standardized math and English tests referred to
(E) explain exactly how high school students’ abilities on math and English tests could have been enhanced by exposure to computers

Ans.(E)
文章的大意還看的懂，但不知道如何解這題，有人可以說說這題的解題想法嗎？

Hi Jack,

你要不要先說說看你所看懂的文意是什麼呢? :)

SORRY!下次我會注意發問的方式，以利自己學習吸收也更容易讓各位高手使的上力！
譯文：在1981年，高中生的英數標準測驗首度在過去二十年裡沒有下降，同年，數以百萬的美國學生首次接觸到電腦的新世界，不論是在學校、video arcades或是其他環境下；結論：接觸電腦可以提高智能

我覺得其他錯誤的原因：
(A)argument的重點在於接觸電腦→提高智能，所以造成測驗分數下降的因素不在討論範圍內
(B)同上:明確的測驗分數不在討論範圍
(C)我選了這個錯誤答案：因為我當時覺得電腦的層面很廣(文中也提及:whether in schools, video arcades, or other settings)、不見得每種都會增加智能;-S
(D)同(A)(B)
(E)後來仔細想想，此答案正確的原因是因為它可以support 接觸電腦→提升智能，是這樣嗎？
請各位大大賜教，謝謝～
