Answer:
How many hours a week do you watch televison?
Explanation:
In order for Mike to organize a survey about this particular topic, it's important that he asks concise questions that provide him with generalized data about multiple days of the week. Because of this, he wouldn't want to ask any questions that solely focus on specific days, so we can use process of elimination to get rid of answer choices C and D. Both of these options are too specific, and only ask about 1 or 2 days instead of a larger period of time. Using the same logic, we can get rid of option A. Option A is also too specific, but for a different reason. This question is only asking about students who watch televison for an hour everyday. Remember, for good surveys, more results provide a better sample of data. So it's important that the questions asked are coherent, but also don't limit the amount of data received either.
