Dear all gmat takers,
I am still confused abt the "Weaken" CR part. Do you have any tips to solve this?
Below is the most headache one I need your help
1. The more frequently employees take time to exercise during working hours each week, the fewer sick days they take. Even employees who exercise only once a week during working hours take less sick time than those who do not exercise. Therefore, if companies started fitness programs, the absentee rate in those companies would decrease significantly.
Which of the following, if true, most seriously weakens the argument above?
A. Employees who excercise during working hours occasionally fall asleep for short periods of time after they exercise.
B. Employees who are frequently absent are the least likely to cooperate with or join a coooperate fitness program.
C. Employees who exercise only once a week in their company's fitness program usually also exercise after work.
D. Employees who exercise in their company's fitness program use their working time no more productively than those who do not exercise.
E. Employees who exercise during working hour take slightly longer lunch breaks than employees who do not exercise.
The correct answer is B. But I see answer choice B is strenghthen the argument not weaken. I feel answer D is more reasonable.
2. A poll of all voters in the state shows that only 11% of all people who voted were younger than 29 yrs old. These results prove that young Americans are not as interested in voting as are older generations. Which of the following statements, if true, would most seriously weaken the author's conclusion?
A. The number of voters in the state under the age of 29 has increased for each of the past 5 yrs.
C. Of all people in the state who are old enough to vote, only 13 % are younger than 29 yrs old.
C is the correct answer. But I feel A is better as it weaken the conclusion that young Americans are not as interested in voting as are the olders.
Please help me to solve these questions above. Appreciate your comments and explanation....
