[A chart is shown with nine items. To the right of each item there are two check boxes. Above the top row of check boxes are two underlined labels for the two columns. The first four rows have both boxes checked, and the last five have only the first box checked. The last two items are so long that they take up three and four rows of text. The first seven items are written on one line each.]
