To begin with, by concluding that the transit company must either reduce shuttle

solutions to the problem of limited shuttle use. However, it is possible that other 2 }9 _8 V, J1 h3 C( O* d! [( D

In addition, the author assumes that reducing shuttle fees and increasing parking ( w6 p. A- J7 z8 U' q) B" u2 S/ i
fees are mutually exclusive alternatives. However, the author provides no reason for

In conclusion, this argument is weak because the author oversimplifies both the
