Martin gets A's (95100) on all of the writing assignments that he does, but he has skipped half of the writing assignments. In discussing his grades with a friend, he says "I must have a C in writing, because I have A's on half the assignments, and F's on the other half." But Martin is worse off than he thinks. He actually has an F in writing. His grade is F because:
A) each student's highest and lowest score were dropped.B) the teacher assigned a zero for every missing assignment.C) the teacher used a system of scoring that is unreliable.D) the teacher was using absolute grading standards.
