### HideShow timer Statistics

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 studentsâ€™ 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 studentsâ€™ abilities on math and English tests could have been enhanced by exposure to computers

I think the OA on this one is wrong.

Between (D) and (E) ,(E).

The argument would be accepted only if the enhancing effects of computers were to be specified.Even if we knew wt intellectual capacities were tested on the tests we do not know for sure if the computer can enhance them.

Were all students equally exposed to computers? Where? When? How often? Too many unknown variables to make such a conclusion.

Straightforward (E) here.

Good job guys..OA is E. As you all might have guessed, I feel for the trap and picked D.

a. Statement ‘a’ is a contradiction to the passage as the scores of students have not declined.So, there are no causes for the decline.
b. It is also not mentioned that the scores have increased over the period. Hence, b could also not be a weakness.
c. Irrelevant to the argument.
d. Failure to define intellectual capacities tested doesn’t hold any relevance to the argument made in the passage.
e. This is the major weakness of the argument as the author has mentioned that the exposure to computers has enhanced students ability and have not provided any link between the exposure to computers and the performance.
