Determining Relative Worth
Comparing and contrasting rarely means placing the item or concept being evaluated in relation to another item or concept that is obviously grossly inferior. For instance, if you are attempting to demonstrate the value of a Cannondale mountain bike, it would be foolish to compare it with a Huffy. However, it would be useful to compare it with a Klein, arguably a similar bicycle. In this type of maneuver, you are not comparing good with bad; rather, you are deciding which bike is better and which bike is worse. In order to determine relative worth in this way, you will need to be very careful in defining the criteria you are using to make the comparison.
