Explanation
The argument follows a pattern where it starts with a conditional statement (if A, then B), acknowledges that not all instances meet the second condition (not all B), and concludes that not all instances meet the first condition (therefore, not all A).
A. This argument reverses the conditional relationship (if A, then not B) and does not match the original pattern of reasoning.
B. This argument does not use a conditional statement but makes a direct inference about Professor Attah's beliefs based on her actions.
C. (Correct Response) This argument mirrors the original pattern:
If a biography is unbiased (A), then it contains embarrassing facts about its subject (B).
Not all biographies contain embarrassing facts about their subjects (not all B).
Therefore, not all biographies are unbiased (not all A).
D. This argument asserts a reciprocal relationship (if A to B, then B to A) and concludes that it must be universally applied, which is different from the conditional pattern in the original argument.
E. This argument presents a direct equivalence (if A, then B) and concludes that if not all A, then not all B. It does not follow the conditional pattern where not all instances meet the second condition (B).
The argument most similar to the original in terms of reasoning is option C, as it follows the same conditional structure and logic.
