The effectiveness of a board chair is best evaluated by:
选项：
A.engaging in direct dialogue with directors.
B.referring to a board self-assessment report.
C.assessing the quality of the directors on the board.
解释：
C is correct. The quality of the directors on the board provides an indirect but otherwise clear signal of the chair’s effectiveness, as strong board members are unlikely to stay on a board led by a weak chair. The other evaluation approaches can be used, but they are considered less likely to provide accurate assessments of the chair’s effectiveness.为什么是C对，A呢？
