An author claims that a new chemistry textbook is excellent because it was written by a Nobel laureate in literature. The argument is MOST suspect because it
AUses ad hominem
BIs too short to assess
CCommits an appeal to inappropriate / irrelevant authority — literature expertise does not establish chemistry-textbook quality
DIs grammatically incorrect
Answer & Solution
Correct answer: C. Commits an appeal to inappropriate / irrelevant authority — literature expertise does not establish chemistry-textbook quality
Appeal to authority is fallacious when the authority is outside their domain of expertise. A literature Nobel does not certify chemistry pedagogy. Citing a chemistry Nobel laureate would not have been fallacious.
