Rate the following argument fragment on its writing, argument, and language skills:
Evidence: Verbal human communication is relied upon to determine what about a lesson plan confuses a student, and although a computer might register a student's confused expression and recognize that the lesson pace might be too fast for this individual scholar, the computer would be unable to pinpoint what exactly the student fails to understand. Other events may be weighing down heavily on a student's mind, causing their face to contort and convey the emotions brought on from factors outside of the learning setting. A change in emotion not caused by a difficult lesson plan would cause the software to possibly alter the lesson pace when the student did not require any adjustment and ultimately generate frustration in the already distressed student.
