Day 137 While the Department of Education in the state of Attra recommends that high school students be assigned homework every day

While the Department of Education in the state of Attra recommends that high school students be assigned homework every day, the data from a recent statewide survey of high school math and science teachers give us reason to question the usefulness of daily homework. In the district of Sanlee, 86 percent of the teachers reported assigning homework three to five times a week, whereas in the district of Marlee, less than 25 percent of the teachers reported assigning homework three to five times a week. Yet the students in Marlee earn better grades overall and are less likely to be required to repeat a year of school than are the students in Sanlee. Therefore, all teachers in our high schools should assign homework no more than twice a week.

Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.

【本题与Day 135相似，不同之处：本题还可以针对“数字与比例不一定等价”进行反驳，在没有给出两个地区教师总人数的情况下，86 percent和less than 25 percent具有参考意义吗？】
