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

The statement is vulnerable to criticism in that it gives reason to believe that it is likely that:
(a) Some celebrities come to Hollywood restaurant to be seen and so might choose to sit at tall tables if they are available
(b) The price of meals ordered by celebrities dining at Hollywood restaurant compensates for longer time, if any, that they spend lingering over their meals
(c) A customer of the Hollywood restaurant who would choose to sit at a tall table would be an exception to the generatlisation about lingering
(d) A restaurant's customer who spends less time at their meal typically orders less expensive meals than those who remain at their meals longer
(e) With enough tall tables to accommodate all Hollywood restaurant's customers interested in such seating, there would be no view except of other tall tables

My take on D

one more D

I think its E

I'm going with E... I think that D is out of scope from the question. The question is asking you to attack the assumption in the passage. The assumption being that if customers have tall tables in order to see celebrities, the restaurant will get more customers and be able to turn the tables faster b/c they will sit for less time.

In E, it says that if there too many tall tables, customers will have the same experiece they had in the standard tables. So you are back to square one. Profits will stay the same.

In D, the passage does not give any reason to assume the amount of money spent in either type of seating will be different. If the question asked to weaken the arguement this would be the correct answer...

Does anyone have the OA?

Should be C.
