Mayor: The city council has proposed additional funding for the town library. However, the library`s own studies show that fewer than 10% of town residents use the library. The city council claims that the library is underutilized because the books, electronic media, and computer equipment are outdated, and that if these were updated, more residents would use the library. However, the last time the town allocated additional funding to the library, usage of the library did not increase. Therefore the town should not allocate additional funding for the library.
Which of the following most seriously weakens the mayor`s argument?
