A standardized testing corporation claims that their college admission test, the TAS, is a reliable indicator of student performance in college, and independent research exists to support this assertion. However, many people who excel in college do not go on to have lucrative careers or fulfilling lives. Therefore, TAS scores do not accurately indicate success outside of the education system.

Which of the following, if true, best weakens the conclusion made about TAS scores?
A) Famed psychologist Charles Xavier has questioned the scientific validity of using a standardized test to predict success.
B) TAS scores were not intended to indicate success beyond college.
C) Studies exist which contradict the findings that the TAS is an indicator of academic success at college.
D) Eighty-five percent of students who scored in the top 25th percentile of the TAS graduate from a four-year college within five years of enrollment.
E) The qualities that lead to success in college are necessary to become successful in other areas of life.

It should be E.

B is TRAP answer choice. It sates that "TAS scores were not intended to indicate success beyond college".
This strengthens the conclusion - "TAS scores do not accurately indicate success outside of the education system."

E states that "The qualities that lead to success in college are necessary to become successful in other areas of life."
Now If the qualities to be successful in college are necessary to become successful in other areas of life then students who score will TAS will always do well in areas outside the education system.
