GMAT Critical Reasoning
In a certain socialist country, party members earn twice as much as non-party members do. But party members happen to work in the businesses that generally have higher wages. Non-party members who also work in these particular businesses earn about as much as party members. Therefore, higher incomes do not necessarily result from the connection with the party.
Which of the following, if true, most seriously weakens the argument above?
- A Besides wage increases, party members also receive other benefits.
- B Some of the most highly paid business people in that country are capitalist executives in special economic zones and are not party members.
- C Wages in many industries vary from one part of the country to another, whether or not workers are in the party.
- D Non-party members in a given industry often receive higher wage as a result of the lobbying done by party members, which in turn increases the wage for the entire industry.
- E Becoming a member of the party within a given industry or business often encourages others to follow suit.
Correct Answer: D
