Parents of some of the children in a particular class have claimed that the teacher is not objective and favors his male students with higher grades. But the record showed that 92% of the female students received a passing grade in this teacher’s class. This record demonstrates that the teacher has not discriminated against women when assigning grades.
The argument above is flawed in that it ignored the possibility that
A. a large number of the teacher’s student were in his class the previous year.
B. many teachers find it difficult to be objective when assigning grades to male and female students.
C. the evidence shows that more than 92% of the female students should have received a passing grade.
D. the majority of tests written by female students and that have been rechecked by another teacher were given a higher grade by the second teacher.
E. the teacher is biased against female students in the case of only some of the subjects he teachers.
