To complete this argument logically, we need to find an option that explains why the Bluewater Hotel is unlikely to see its revenue drop to half of a normal year's revenue, even though it was closed during the first quarter—a period that typically accounts for half of its annual revenue.
(A) talks about next year's revenue and (B) talks about other hotels so we can
eliminate both (A) and (B) since they're irrelevant.
(C) the cost of the repairs was less than half of a normal year’s revenue
The argument is concerned with revenue, not costs. Even if the repair costs are low, it doesn't explain how the Bluewater will earn enough revenue to compensate for the first-quarter closure.
Eliminate (C). (D) it is extremely unlikely that any storm this year will be so severe as to cause damage comparable to the damage caused by the storm last year
This talks about the likelihood of future storms but does not address how the hotel will make up for the lost revenue this year. It is irrelevant to the current year's revenue situation so we can
eliminate (D) as well.
(E) many of the customers who would ordinarily have stayed at the Bluewater during the first quarter will probably reschedule their stay for later in the yearThis option directly addresses the issue. If many customers reschedule their stays for later in the year, the hotel can potentially make up for the lost revenue from the first quarter. This explains why the hotel's total revenue for the year might not drop to half of a normal year's revenue.
Hence
(E) most logically completes the arugment.
