At present the Hollywood Restaurant has only standard-height tables.However, many customers come to watch the celebrities who frequent the Hollywood, and they would prefer tall tables with stools because such seating would afford a better view of the celebrities.Moreover, diners seated on stools typically do not stay as long as diners seated at standard-height tables.Therefore, if the Hollywood replaced some of its seating with high tables and stools, its profits would increase.

The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that

(A) some celebrities come to the Hollywood to be seen, and so might choose to sit at the tall tables if they were available

(B) the price of meals ordered by celebrities dining at the Hollywood compensates for the longer time, if any, they spend lingering over their meals

(C) a customer of the Hollywood who would choose to sit at a tall table would be an exception to the generalization about lingering

(D) a restaurant's customers who spend less time at their meals typically order less expensive meals than those who remain at their meals longer

(E) with enough tall tables to accommodate all the Hollywood's customers interested in such seating, there would be no view except of other tall tables

Premises:
1) Customers come to Hollywood Restaurant to watch the celebrities so customrs would prefer tall tables to get a better view.
2) Diners seated on stools typically stay a shorter time than diners on regular seats.

Conclusion:
If the Hollywood replaced some of its seating with high tables and stools, its profits would increase.

Basically, the argument says that stools would attract more customers and customers sitting on stools turn over quickly.  
Therefore, profits would be up.  Wait a minute.  Based on premise 1, if the customers are attracted to the restaraunt because they
want to see celebrities, shouldn't they stay LONGER than normal customers? If so, it runs contrary to premise 2 which describes
a general trend in customer's lingering behavior. The customer attracted might sit on the stools for a LONNNNNNNNNNNNNNG time without spending much on food. No turnover, no money!

C points out this paradox and C is the correct answer.

The most important, this question is not to ask which answer choice weakens the argument, but actually the question is to ask which answer choice is an assumption based on which the conclusion have been made.
It's quite tricky:p

同意楼上观点，这题仔细读题发现是assumption题，而不是weaken题。
