@lunnington: Yeah that question really bugged me too.
Some of those questions I wasn't so sure on, like whether it is better to improve inflation or unemployment. I've never really understood the forces that move the economy particularly well.
Yeah that one was a dumb question. Unemployment in economic terms is the biggest factor because it refers to not only unemployment of workers but also resources. If you control unemployment then you can usually control inflation. In the real world I doubt anyone actually chooses between the two. It's like saying "well do I maintain my car or my house?" Well, you should probably maintain both.
Ahh thanks for the explanation. I remember learning that inflation and unemployment were inversely related but it seems that is not a hard rule.
