Why not C

If it takes at least two month to process than we can guarantee that the library will not be built on schedule.

@noellerubino,

Great question. This is a strengthen with a sufficient premise
question. We're looking for the answer choice that, if true, makes the
argument valid.

The argument is saying

P: No building permit and other activities not completed in less
time - >no library
P: No building permit
C: no library

This argument isn't valid, but if we add the other sufficient
condition of the first premise, we could make it valid.

(C) says, "The application for a building permit was submitted on
January 2 of this year, and processing building permits always takes
at least two months. supported by the study."

(C) gives us additional information regarding why the permit will not
be obtained by February 1, but we already know that it won't be
obtained by February 1, so we are not getting any new information to
make the argument valid. As a result, we can get rid of this answer
choice.

(A) says, "All of the other activities necessary for construction of
the library will take at least as much time as originally planned."

(A) helps us to satisfy the second sufficient condition of the first
premise we were given in the stimulus. With (A), we have enough info
to make the conclusion that the library will not be built, so (A) is
the correct answer choice.

P: No building permit and other activities not completed in less
time - >no library
P: No building permit
P: (A) other activities not completed in less time
C: no library

Does this make sense? Let us know if you have any more questions!
