Mayor: the commuters from the nearby suburb of Coldstream perennially complain of a difficult commute to our downtown region. To address these concerns, we should install high-speed toll collector on the interstate between here and Coldstream, thus relieving any traffic snarls caused by the hand-operated toll booths.
Civil engineer: Over 95% of commuters from Coldstream take local roads, not the interstate, to our downtown region.
The civil engineer uses which of the following techniques in responding to the mayor?
(A) pointing out that the premise could lead to an opposing conclusion
(B) questioning whether the methods recommended would work in practice
(C) citing evidence that calls into question the assumption of the argument
(D) suggesting, by analogy, that the argument might not support the conclusion
(E) presenting evidence that the proposed solution would have damaging unforeseen consequences

B: Civil engineer never mentioned that the tolls will fail in alleviating traffic.
C: Correct, this is exactly what the CE is doing
D: No mention of an analogy
E: CE premise has nothing to do with the tolls
