In 1981, for the first time in over two decades, the average [#permalink]
 27 Mar 2007, 16:09
Question Stats:
0% (00:00) correct
 0% (00:00) wrong based on 0 sessions
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

A for me.
B, C, D are clearly irrelevant.
As for E, when "exposure to computers can actually enhance them" further explaining how it can enhance will clarify/help, but its omission doesn't really "weaken" the argument.

The paragraph makes a claim that there is a connection between math and English scores (intellectual capacity) and exposure to computers. However, we are not sure how the author came to this conclusion. Are the scores not declining anymore because students can access information that couldn't access before? Or maybe the access is easier and/or faster? What is it? Going through the answer choices, E seems to address this issue. Hence, I choose E!

Arg says
avg score did not decline
at the same time computers are introduced
No causality is explained in the arg.
E exposes the weakness of causality

Again...got wrong on a 50:50 one.
Guess I'm just bad at choosing the right answer between two choices

E is clearly the answer, though D seemed right at first.
