I believe it's the word "privilege". In literature, tone is the author's attitude toward the subject he/she is writing about. Marian Angerson's tone is elevated here, which tells us that she really is excited to exercise this privilege, as a representative of the workers' class of women.
Answer and Explanation:
I agree that the grade system, used in most schools, is not the most appropriate for establishing effective learning for students. In addition to, in fact, rewarding students unevenly and encouraging competitiveness (which does not promote learning), the grading system encourages students to memorize the subjects that are passed on to them, instead of actually learning. As we all know, the decorated concepts will be quickly forgotten by the brain, which will consider this a season memory.
However, evaluating students for their written and oral skills, promotes a totally different activity. This is because students will not feel obliged to decorate, but rather to understand the subjects, to create well-structured thoughts for the evaluations that will be submitted. This search for understanding will lead to effective, complete and lasting learning.
The answer is A. Hope I helped :)
