Explain whether a bar graph, double bar graph, or circle graph is the best way to display the following set of data:the number of teens who attended art museums, symphony concerts, rock concerts, and athletic events in 1990 compared to the number who attended the same events this year.

A double bar graph is best because it compares two related sets of values across the same categories. Here, the two sets are attendance in 1990 and this year, and the categories are art museums, symphony concerts, rock concerts, and athletic events. A circle graph is better for showing parts of one whole, while a single bar graph would not show both years as clearly.
