The author of the following passage relies primarily on which type of rhetorical appeal:
"Houston's Computers for Kids program (C4K) helps children from low-income families gain the
type of computer literacy that will help them be competitive within the modern job market.
Opponents of the program argue that it is ineffective because the number of low-income children
lacking computer literacy has risen by over four hundred in the four years since C4K was founded.
But these opponents are not taking into consideration that, due to overall economic decline, the
total number of low-income children has risen dramatically within those four years. When we take
that into consideration, we find that C4K has helped to lower the rate of computer illiteracy among
low-income children by more than 15%."
