Answer:
Correct options are:
A, D, & E
Explanation:
Secondary questions are questions that follow up primary questions. They are questions asked in order to get additional information, also, they do not make sense on their own. Secondary questions complement primary questions because the secondary questions make no sense when asked alone.
In this case, the primary question should be "what are the effects of recess?" So, the secondary questions here should focus on the effects of recess.
From the given options, the questions that focus on the effects of recess are:
i) What is the effect of recess on student behavior?
ii) Why do some people believe that recess should be longer?
iii) How many minutes of recess are recommended for good health?
Option B and C are incorrect because they do not focus on the effects of recess, rather, they are related to other aspects of recess.
