For next year, the Chefs’ Union has requested a 10 percent salary increase for each of its members, whereas the Hotel Managers’ Union has requested only an 8 percent salary increase for each of its members. These facts demonstrate that the average dollar amount of the raises that the Chefs’ Union has requested for next year is greater than that of the raises requested by the Hotel Managers’ Union.
Which one of the following, if true, most strengthens the argument?
A. The Chefs’ Union has many more members than does the Hotel Managers’ Union.
B. The Chefs’ Union is a more powerful union than is the Hotel Managers’ Union and is therefore more likely to obtain the salary increases it requests.
C. The current salaries of the members of the Chefs’ Union are, on average, higher than the current salaries of the members of the Hotel Managers’ Union.
D. The average dollar amount of the raises that the members of the Chefs’ Union received last year was equal to the average dollar amount of the raises that the members of the Hotel Managers’ Union received.
E. The members of the Chefs’ Union received salary increases of 10 percent in each of the last two years, while the members of the Hotel Managers’ Union received salary increases of only 8 percent in each of the last two years.

Which one of the following, if true, most strengthens the argument?
A. The Chefs’ Union has many more members than does the Hotel Managers’ Union. - INCORRECT. Even if more members are there, a significantly lower base for Chefs' Union relative to Hotel Managers' Union would make average dollar amount of the former lesser than latter.
B. The Chefs’ Union is a more powerful union than is the Hotel Managers’ Union and is therefore more likely to obtain the salary increases it requests. - INCORRECT. Even if so, the logic as in option A nullifies this option.
C. The current salaries of the members of the Chefs’ Union are, on average, higher than the current salaries of the members of the Hotel Managers’ Union. - CORRECT. Higher bases leads to higher dollar amount.
D. The average dollar amount of the raises that the members of the Chefs’ Union received last year was equal to the average dollar amount of the raises that the members of the Hotel Managers’ Union received. - INCORRECT. Nothing concrete about last year's raises/salary is given.
E. The members of the Chefs’ Union received salary increases of 10 percent in each of the last two years, while the members of the Hotel Managers’ Union received salary increases of only 8 percent in each of the last two years. - INCORRECT. Again same logic as that of A weakens this choice.
IMO Answer C.

OFFICIAL EXPLANATION
This problem makes the classic mistake of assuming that a larger percentage translates into a greater number (Misconception #6). According to the argument, because the Chef’s Union requested a 10% raise and the Hotel Manager’s Union requested only an 8% raise, the Chef’s Union must have asked for more money than the Hotel Manager’s Union. But, the argument never tells us how much the average member of each union makes, so the conclusion cannot be drawn with certainty, as shown by the following example:
Even though the Chef’s Union has asked for a greater percentage raise than the Hotel Manager’s Union, it is still possible that the actual dollar amount of the Hotel Manager’s Union request is greater. In this case, omitting the average current salary made by each member is tantamount to omitting the total amount made by the members, and thus, even though this problem uses averages, it trades on the mistake behind all the misconceptions discussed at the beginning of this chapter. To strengthen the argument, you must find an answer that indicates that the Chef’s Union has a wage that is equal to or greater than the wage of the Hotel Manager’s Union (the wage could also be very slightly below that of the Hotel Manager’s Union).
Answer choice (A): Because the conclusion is specific about the average dollar amount requested, and an average can be calculated regardless of how many members are in the union, this answer is irrelevant to the argument.
Answer choice (B): The argument focuses on the size of each Union’s raise request. Whether each union will receive the request is not at issue, and thus this answer is incorrect.
Answer choice (C): This is the correct answer. As discussed above, an answer that indicates that the Chef’s Union has a wage that is equal to or greater than the wage of the Hotel Manager’s Union would strengthen the argument. This is the answer you should look for when you read the question stem, and you should attempt to accelerate through the answer choices to find this answer.
Answer choice (D): This answer refers to the raises given out last year. Unfortunately, this fails to address the current salaries of the union members.
Answer choice (E): Like answer choice (D), this answer addresses previous raises, which does not tell us about current salaries.
