In some circumstances, yes! For example, if you read 1 hour of a graphic novel in a blanket fort you can mark off all three of those boxes on your bingo card! We are impressed by your efficiency! But if you read 1 hour, you can only mark a single "Read 1 hour" box on your bingo card, then mark another box after you have finished reading for another hour. We are librarians after all, we really love when you read!
