You present strong arguments to college students to support your claim that tuition and fees at state colleges are too high. You strongly encourage audience members to make a trip to the state capital and petition legislators to lower tuition rates.
It is unlikely that many audience members, if any, will follow your suggestion because:

A. the effort required to visit legislators is too great.
B. you've used the peripheral route to persuasion.
C. you've created cognitive dissonance.
D. behaviors are almost never consistent with attitudes.

A. the effort required to visit legislators is too great.

Explanation:

Even though, i have a strong argument to college students to support my claim that tuition and fees at state colleges are too high. Many of the audience will unlikely not follow my suggestion of traveling to the state capital and petition the legislator because the effort required to visit legislators is too great.

In other words, for the audience to make a trip or travel can be costly, and process of lodging the complain or petition at the legislation can be tedious. Hence, many audience will find the effort to be too great to consider.
