### 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 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

Answer is E.

We need to look carefully at what the conclusion actually is (which is quite clearly stated in the last sentence).

A - Past 21 years of scores is not a mater of concern while discussing the sudden rise in scores this year as conclusion is concerned with the present development only.
B- Doesn't answer HOW
C - Irrelevant (How will that ever help?)
D - Definition of intellectual capacity doesn't attack the argument.

E- CORRECT!

Hi shahidomer77

Two reasons why B is wrong:
1. If you read the argument, it states that Scores did not decline. B States that the scores have increased

2. B States that the scores have increased and the argument should provide figures to prove it: Now imagine if the scores went up by 80% - does this help our argument that computers aid learning? No!

So E is the LEAST wrong answer here
