In my story on sustainability the author uses a few rhetorical tools.  One of them is a comparison between a truck running on hydrogen and a standard diesel truck.  One thing interesting about this tool he used is that it kinda went against his point. He made it seem like diesel is a much better option because they are less expense then a hydrogen truck, they run better then hydrogen, It feels better to drive a diesel and other reasons.
In this whole article the author continually uses evidence to show that we should use clean burning fuel from plants rather than the fossil fuels that we are using and that we are running out of.  He also gave the examples like the truck driver in Switzerland which is another rhetorical tool. This goes to show how many rhetorical tools are used in writing everywhere.
