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 Redville, 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 Redvilte 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.

D．Many of the people who use the public library do not live in either Glenwood or Redville.

E．(E) The distance that people currently walk to get to the library is farther than what is generally considered walking distance.
