Passage Summary: A rule states that authors can respond to harsh criticism if it appeared in the same magazine or if it was unfair and appeared elsewhere. McFinton wants to respond to Wallace's mean article in Speculator's Digest.

Conclusion: McFinton should be permitted to publish a response to Wallace's article in Speculator's Digest.

Reasoning: Wallace's article was harshly critical of an essay written by McFinton.

Analysis: To justify the application of this principle, we need to satisfy one of the two conditions provided. We know the criticism was 'harsh,' but we are missing a key link: either Wallace's article was also in Speculator's Digest, or it was published in a different magazine and was 'unfair.' Look for an answer that provides one of these missing pieces of information. Without knowing the location or the fairness of Wallace's critique, the principle doesn't yet apply to McFinton's situation.
