Each of the items numbered 1 through 25 consist of a pair labeled (1) and (2). Use the following key to indicate whether (1) is greater than, less than, or approximately equal to (2).
Check:
A. if (1) is greater than (2)
B. if (2) is greater than (1)
C. if (1) and (2) are approximately equal.
For example:
(1)The number of people living in Chicago.
(2)The number of people living in Carbondale.
In this example, (1) is greater than (2) so you should check circle A.
