Traditionally, public school instructors

Traditionally, public school instructors have been compensated according to
seniority. Recently, educational experts have criticized the system as one that
rewards lackadaisical teaching and reduces motivation to excel. Instead, these
experts argue that, to retain exceptional teachers and maintain quality instruction,
teachers should receive salaries or bonuses based on performance rather
than seniority.

Which of the following, if true, most weakens the argument of the educational
experts?

(A) Some teachers express that financial compensation is not the only factor
contributing to job satisfaction and teaching performance.

(B) School districts will develop their own unique compensation structures that
may differ greatly from those of other school districts.

(C) Upon leaving the teaching profession, many young, effective teachers cite a
lack of opportunity for more rapid financial advancement as a primary factor
in the decision to change careers.

(D) In school districts that have implemented pay for performance compensation
structures, standardized test scores have dramatically increased.

(E) A merit-based system that bases compensation on teacher performance
reduces collaboration, which is an integral component of quality instruction.
