Scientificity The questions raised must conform to objective laws and be appropriate and accurate in depth, consistent with students’ knowledge of laws and characteristics, and take into account students’ mastery of basic sports knowledge, basic techniques, and basic skills.

They are too simple and meaningless. They cannot mobilize students’ enthusiasm for learning.
