# Brief Explanations: To determine homogeneity between two groups using a stacked - bar graph, we look for similar proportions of the categories within each bar. In option B, the stacked - bar graphs for 9th and 10th graders have similar proportions of the different meat - eating categories, which can be used to assess homogeneity. If the proportions of the segments in the stacked bars for the two groups are similar, the groups can be considered homogeneous in terms of the variable (meat - eating in this case). # Answer: A. Option B B. The groups appear to be homogeneous if the proportions of the segments in the stacked bars for 9th and 10th graders are similar. For example, if the percentage of students who eat a certain kind of meat is about the same in both 9th and 10th grades, it suggests homogeneity.
