The author of a new art history book argues that students whose paintings come to be received as masterpieces achieve greatness by perfecting the technique and vision of their teachers. To support this theory, the author provides a detailed comparison of the works of 15 student-teacher pairs, in each case demonstrating that the teacher’s work is superseded by the student’s.
Which of the following, if true, is most damaging to the conclusion reached by the author of the art history book?
The book does not include any side-by-side illustrations comparing the work of students to the work of their teachers.
The author does not consider the fact that, in student-teacher pairs, both artists can produce either masterpieces or low-quality works.
The author does not give sufficient attention to the historical context of each masterpiece produced.
The author chose for inclusion only those artists whom he considered to have surpassed their teachers, and then examined the relationship of their respective paintings.
The author concentrates almost exclusively on the techniques developed by the teachers, and does not give sufficient attention to the execution of technique by the students.
