Marketing strategists at a major video retailer are discussing ways to
increase revenues by boosting mid-week DVD rentals, which generally
fall far below weekend rentals. One plan to accomplish this is to extend
the return date for DVDs rented between Monday and Wednesday so
that customers may keep them until Friday. Since more customers will
return to the store on Fridays, they will be also be more likely to rent
again for the weekend.

Which of the following, if true, would indicate the most serious weakness
in the plan above?

(A) The number of clerks currently employed by the video retailer is not
sufficient to handle a significant increase in business on Monday, Tuesday,
and Wednesday.
(B) Customers who are lured by extended return dates for mid-week DVD
rentals are much less likely than the average customer to rent a DVD on Friday.
(C) Even if the video retailer increases its mid-week rentals, some customers
will continue to rent only on Fridays.
(D) The video retailer currently offers two-day rentals, so the plan would not
provide an additional inducement to rent DVDs on Wednesday.
(E) The video retailer would rent more DVDs by extending return dates on
Friday and Saturday rentals than on Monday through Wednesday rentals.
