results of my survey

Arnold Schwarzenegger is planning to retrofit his Hummer to run on hydrogen. What do you think of this idea?

82 students picked a. This is a good technological fix--Americans aren't going to give up SUVs so we should make them more environmentally friendly.
13 students picked b. This is a foolish technogical fix--the Hummer is an example of the excess that harms our environment. We need to change our values and behavior, not think we can have it all.

Did I go too far in trying to phrase my answers so as not to slant the results? Or is it simply that student do think they can have it all?
