D). The nonfictional excerpt describes the reaction to the regulations.
Explanation:
As per the question, the key distinction between the presentation of regulations in the fictional and non-fictional excerpt is that the latter(non-fictional excerpt) offers a response to the ordinances presented in the former(fictional excerpt). The fictional excerpt simply reveals the directions that people are required to follow during the quarantine(should avoid...should be marked, etc.) while the non-fictional description aims to depict the reaction of setting these regulations('cutting off...shut us out'). Thus, <u>option D</u> is the correct answer.
