Read the excerpt from "Compulsory Voting: An Idea Whose Time Has Come":

However, our society does impose obligations on citizens when the success of our nation is at stake. Two examples are jury service and paying taxes. Government cannot provide necessary services without revenue, nor can the justice system operate without juries. Imagine the result if jury duty were voluntary. Similarly, our nation suffers from our citizens' negligence at the polls.

Which research question does this paragraph best address?

A. Why do Americans dislike compulsory voting?

B. What other countries require compulsory voting?

C. Why are Americans reluctant to vote?

D. What compulsory duties are already required of Americans?

A research question is the point of departure for any research. It states the question that the research attempts to solve and serves as guidance for your investigation. In this example, the investigation resulted in a discussion of other compulsory duties that the government expects from citizens. If the research was conducted carefully, this information would answer the question: what other compulsory duties are already required of Americans?
