Answer: C
Step-by-step explanation:
Option C, "These two news stories, though written by different reporters, expressed the same message" would best conclude the comparison of the central ideas of two different newspaper articles. This option clearly indicates that the student has identified a common message or theme between the two articles, which is the primary purpose of comparing them. It also acknowledges the difference in authorship while still highlighting the similarity in the message, indicating a thoughtful and nuanced analysis. Option A is too vague and lacks specificity, while option B only comments on the writing style, which may not necessarily be the main focus of the essay. Option D suggests further analysis but does not explicitly tie into the comparison between the articles.
