Pls c is read the research question. why do high school students not spend enough time doing physical activity each day? which statement is the best evaluation of the research question? a) it is too biased; this research question contains an opinion and cannot be answered through research. b) it is clear and complex; this research question has a single focus that can be researched and discussed. c) it is too broad; this research question is unfocused and would be too difficult to discuss in a single research essay. d) it is too narrow; this research question is limited to high school students, which is not a large enough group to research.

The statement that best evaluates the research question above is A "It is too biased; this research question contains an opinion and cannot be answered through research." because the question does contain an opinion when it asks about 'enough time' for physical activity within the certain population of high schoolers; thereby anyone can ask "How much is 'enough' for this activity?" as each person has his/her own concept of time for a proper physical activity, and with the question it is assumed that ALL students in high school do not spend sufficient time on it, whereas there may be students who practise some sport. Instead of asking the why, the question should be stated to ask for the how much time or how many minutes high schoolers spend on doing physical activity.
