Final answer:
Effective research questions should be narrow, clear and concise, answerable, and of consequence.
Step-by-step explanation:
Effective research questions have certain characteristics that make them valuable for conducting research. A research question should be narrow instead of broad, as a narrow question allows for a focused investigation. It should also be clear and concise rather than vague, to ensure that it is specific enough to guide the research. A research question should be answerable and have the potential for multiple possible answers. It should also be of consequence, meaning that the outcome of the research should matter and affect others.
