Hotel bookings in Miami are only done through travel websites. In 2011, there were 50,000 fewer hotel room night bookings then there were in 2010. Hotel owners are blaming the apartment renting service by new website Miami@50 that not only sells hotel room bookings at bargain prices but also allows people to rent out their houses. The website owners dispute the charge stating that they only rented out only 8,000 apartments through their website. They claim that the down economy and not their website is responsible for majority of the decline in hotel room bookings.

Which of the following if true most seriously weakens the Miami@50 owners claim?

A. Miami@50 rents apartments at a much lower price then it rents hotel rooms.
B. Miami@50 rented out at least 8 times as many hotel room nights bookings as apartments.
C. Most apartments in that Miami@50 rented out were rented out multiple times.
D. Miami@50’s profit from renting out apartments was higher than it was for renting out hotel rooms.
E. Most of Miami@50’s customers preferred renting an apartment to renting a hotel room
