HELP WILL MARK BRAINLIEST! SOURCE 1: From an editorial in the Northwest Central Times:
Yesterday, Professor John Willerby was awarded a Certificate of
Excellence in Education by the president of Northwest Central
University. Students who pass his Psychology 101 class score higher
on the Social Sciences Aptitude Test by a staggering margin of 90
percent on average. His excellent teaching and his students' excellent
work are truly representative of NCU's high standards in education.
SOURCE 2: From a student email: I am really freaking out about
Willerby's class. Sure, students who graduate from Psychology 101 do
way better on the Social Sciences Aptitude Test than everybody else,
but only 10 percent of them actually pass! The man puts a cap on the
number of students who can score a satisfactory grade, so even really
good students fail. And the ones who do pass aren't even that good.
They're just more competitive. One of these "model pupils" checked
out all of the psychology books in the library so that nobody else could read them!

Which claim do the two
sources most clearly disagree on?
A. Professor Willerby's students score better on the Social Sciences Aptitude Test because of their hard work, his excellent teaching style, and his fair grading practices. B. Professor Willerby is responsible for teaching Northwest Central University's Psychology 101 class.
C. Professor Willerby has faced a lot of criticism by the university for the number of good grades he gives out .
D. Professor Willerby's students score much higher on the Social Sciences Aptitude Test than the national average .
