Instead, an effective research question is one that is challenging, probably controversial and one that does not have one correct answer but multiple answers which allows the researcher to look for multiple sources of information and find suitable answers based on the comparison of the information found and then report the results of all the process. Therefore, the most effective type of research question is a question that is challenging and does not have one correct.
