This is a common flaw on the GMAT - the premises provide two possible explanations for a fact and the author eliminates one of the explanations therefore coming to the conclusion that the other explanation must be correct. However, the author has never clearly stated that the first to explanations are the only ones. Thus the flaw is that there could be additional explanations and eliminating one does not make the other necessarily true. Thus E is the correct answer.
Absenteeism among employees has decreased steadily over the past several years. Two
possible explanations have been offered. First, improved health insurance has allowed
employees to maintain better health. Second, improved working conditions have improved
morale, leading to less desire to avoid work. However, since absenteeism has also decreased
at companies with poor or no health insurance and poor working conditions, one must
conclude that the cause of the decrease is the increased tendency of employers to deduct
missed days from employees’ paychecks. Which of the following indicates a flaw in the
A) Employees who lack health insurance often have low morale.
b) Companies with poor working conditions are most likely to deduct pay for missed work days
c) Most employees are not honest about the reasons that they miss work
d) The definition of absenteeism is not clear
e) Improved health care, improved working conditions, and fear of losing money are not the
only possible explanations for decreased absenteeism
