Final answer:
In response to a motion to refer the main question to a committee, the chairman should follow parliamentary procedure by discussing and voting on the motion, and if passed, delegate the task to the committee and oversee the committee process.
Step-by-step explanation:
As the chairman at a meeting where a motion has been made to refer the main question to a committee, the appropriate action would be to follow parliamentary procedure. This involves discussing the motion, allowing debate among the members if the motion is debatable, and then proceeding to a vote. If the motion passes, the chairman would select or confirm the members of the committee (unless already specified) and delegate the task to the committee.
The committee process in legislative bodies entails a series of methodical steps such as requesting comments from relevant agencies, holding hearings with non-committee experts, amending the measure, and ultimately sending the measure back to the full chamber with a committee report.
