If the public library shared by the adjacent towns of
   Redville and Glenwood were relocated from the
   library's current overcrowded building in central
   Redville to a larger, available building in central
   Glenwood, the library would then be within walking
   distance of a larger number of library users.
   That is because there are many more people living in
   central Glenwood than in central Redvilte, and people
   generally will walk to the library only if it is located
   close to their homes.
   Which one of the following, if true, most strengthens
   the argument?
   (A)The public library was located between Glenwood
       and Redville before being moved to its current
       location in central Redville.
  (B) The area covered by central Glenwood is
       approximately the same size as that covered by
       central Redville.
   (C) The building that is available in Glenwood is
       smaller than an alternative building that is
       available in Redville.
  (B) Many of the people who use the public library do
        not live in either Glenwood or Redville.
   (E) The distance that people currently walk to get to
        the library is farther than what is generally
        considered walking distance.

Why B?

of course B.
The author's reason are: G has more people and people will walk only if it is located
   close to their homes.
To strength this argument you need to stength it's assumptions or make reasons more persuasive.
If G and R don't cover the same area ( suppose G covers a very large area),then the things he listed above can't logically to result "the library would then be within walking distance of a larger number of library users"

Other choice can be easliy eliminated.
