A teacher requires the class monitor to distribute review sheets for Chinese, English, Mathematics, Social Studies, and Science—5 subjects in total—over Monday, Tuesday, Wednesday, and Thursday of next week. At least one subject's sheet must be distributed each day for students to take home for practice and submit the next day. Since there are Chinese and English classes on Tuesday, the Chinese teacher requires that the Chinese sheet must be distributed on Monday for review; and the English teacher, having assigned other work that day, requires that the English sheet not be distributed on Tuesday. According to these requirements, the class monitor has ways to arrange the distribution.
