How important is the information thats put in between the two columns?
This information is very important. Whenever you see information in between the columns of a QC, you need to pay close attention to it. This information will almost always be important for making the comparison, especially if there is algebra involved in the question. The information could limit the value of a variable (it will say something like x>0), or it could give you an equation that you will have to use to be able to compare the columns (like a+1=b). If you see a QC with something between the columns, start your attack on the question with this information.
