Unless the building permit is obtained by February 1 of this year or some of the other activities necessary for construction of the new library can be completed in less time than originally planned, the new library will not be completed on schedule. It is now clear that the building permit cannot be obtained by February 1, so the new library will not be completed on schedule. The conclusion drawn follows logically from the premises if which one of the following is assumed?
A: The officials in charge of construction of the new library have admitted that it probably will not be completed on schedule.
B: It is not possible to convince authorities to allow construction of the library to begin before the building permit is obtained.
C: The application for a building permit was rejected the first time it was submitted, and it had to be resubmitted with a revised building plan.
D: All of the other activities necessary for construction of the library will take at least as much time as originally planned.
Choose A, B, C or D as your solution.
