Bob’s Café, a busy restaurant, has decided to stop serving steak, which takes much longer to cook, and concentrate instead on poultry dishes. The management believes that this will allow servers to speed up customer turnover and therefore maximize profits by serving as many customers as possible at each meal.
The Bob’s Café management’s plan to speed up customer turnover would be most undermined by which of the following?
A. Chicken takes only half as long to cook as steak in most instances.
B. Chicken is less expensive than steak for Bob’s Café to purchase.
C. Chicken dishes can be sold for nearly as much as steak dishes.
D. The bistro next door to Bob’s Café will continue to serve steak.
E. Customers who order chicken tend to order dessert much more frequently than do customers who order steak.
I am not convinced with OA and OE, i will post the OA after some responses..
Responding to a pm:
The cafe has decided to stop serving steak since it takes too much time. So the assumption is that people who order steak right now will start ordering chicken and hence customer turnover will increase. More customers will mean more profits.
Now, many things can undermine this argument since we made many assumptions. Some of these things are:
1. Chicken sells at a much cheaper price than steak.
2. Customers who want steak will switch the cafe rather than the meat.
3. Customers who eat chicken take much longer to finish than customers who eat steak.
etc
Let's look at options (C), (D) and (E)
C. Chicken dishes can be sold for nearly as much as steak dishes.
This strengthens our argument. Chicken cooks faster so leads to higher customer turnover and sells at the same price so it does lead to higher profits.
D. The bistro next door to Bob’s Café will continue to serve steak.
This option kind of hints at "people may switch cafes" but it doesn't say so. We don't know whether people will switch cafes or meat so it doesn't undermine the argument. We need an option to specify that they will prefer to switch cafes.
E. Customers who order chicken tend to order dessert much more frequently than do customers who order steak.
This is no. 3 in our list above. If people who eat chicken order dessert too, they will take longer to finish and hence the customer turnover may not increase. It may actually decrease. We don't know the cost of dessert and hence cannot say anything about profits. But this option does undermine our "increase customer turnover" logic.
Hence answer (E)
