The university recently announced that it is considering shifting to an anonymous grading system. The school would assign each student a random testing number. The numbers would vary throughout the year, ensuring that professors cannot identify specific students. Students receive final grades based on their test scores. As students, we feel this change should not be made. We are concerned that the anonymity leaves an assessment void where in-class performance is discounted.

What underlying assumption is this argument based on?
A. that having an anonymous number won't help students become better test takers
B. that it would be easier and more efficient to grade tests using a number system
C. that teachers should also consider in-class performance when determining a student's grade
