Answer by Clicking on a Table

Tables are divided into cells. A cell is the intersection of a row and a column. Select a cell by clicking in it. The program will then either fill (mark) the cell or change the entry. The keyboard can also be used for entry. Which cell is selected can be changed by using the cursor arrow keys. Press the <space bar> to mark the selected cell. Erase by selecting a different cell.

Data such as the parts of an argument are sorted on tables. On most tables, each part occurs in a different row and each possible label for the parts in a different column. On the other tables, the row/column arrangement is reversed; the labels occur in the rows and the data in the columns. Sort a datum by selecting the intersection of a row and a column.

Special considerations:

In exercise sets 1.1 and 1.5, there may be unused labels. One of your tasks is to decide what to ignore.

In most exercise sets, each datum has one label. However, according to the instructions for exercise set 2.2, numbers 2 and 3, each datum there has three labels. In 2.2, pick the best answer from among the given labels. If the program prefers a different answer than yours, talk it over with your instructor. The program is trying to assure that each term has three labels. It may view your choices not as plainly wrong but rather as more appropriate for a different term.
