Matching
In matching questions, you are given two columns of related information; for example, words in one column and definitions in the other. One column has green boxes with numbers beside them; the other column has empty boxes in front of each item. You place the number of an item in the box next to the corresponding item in the second column. If the information in one column is too long for both columns to fit, the second column appears below the first.
