The correct answer is (E): Miteki fails to address the substance of Lito's claim by making a secondary argument.
Lito's point (Conclusion): Increase safety by widening these bridges to prevent future accidents.
Evidence: One-lane bridges causes increasing number of car accidents
Miteki's response: Environmental preservation => One-lane bridges were originally installed to minimize environmental impact.
Miteki's response does not directly refute or address Lito's primary concern about traffic safety. Instead, it brings a new point into the argument about environmental integrity.
(A) Relies on faulty information to support her argument
Miteki doesn’t use incorrect or faulty information. Her environmental concern is valid, even if irrelevant. Incorrect.
(B) Uses circular reasoning to make her main points
Circular reasoning involves using the conclusion as a premise, but Miteki provides separate reasons (environmental integrity and potential harm to wildlife) to support her argument. Incorrect.
(C) Focuses on a minor issue instead of a more important one
How do we decide which issue is a minor and major one? Environmental impact is simply not relevant to the safety-focused argument Lito makes. Incorrect.
(D) Responds to a supporting point instead of a main point
Miteki doesn’t address a supporting point from Lito; she introduces an unrelated issue (environmental harm). Incorrect.
(E) Fails to address the substance of Lito’s claim by making a secondary argument
This correctly identifies the flaw. Miteki ignores Lito’s central claim about safety and the need to prevent accidents, instead focusing on environmental concerns, which are secondary to the argument. Correct.
Therefore, option (E) is the answer.
