Question

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? it is too broad; this research question is unfocused and would be too difficult to discuss in a single research essay. it is too narrow; this research question is limited to high school students, which is not a large enough group to research. it is too biased; this research question contains an opinion and cannot be answered through research. it is clear and complex; this research question has a single focus that can be researched and discussed.

Explanation:

A good research question should be clear, complex, and have a single focus that can be researched and discussed. The question "Why do high school students not spend enough time doing physical activity each day?" is clear (asks about the reason for lack of physical activity time among high - school students) and complex (implies multiple factors could be at play). It has a single focus (high - school students' physical activity time) which can be researched (through surveys, data on student schedules, etc.).

• The first option about being too narrow is incorrect as the question is not limited in scope (it's about a general group of high - school students).
• The second option about being too broad is wrong because it's focused on a specific group (high - school students) and a specific activity (physical activity).
• The third option about being biased is incorrect as it doesn't contain an opinion (it's a neutral question asking for a reason).

Answer:

It is clear and complex; this research question has a single focus that can be researched and discussed.
