The anatomy of an argument

Question 1 of 9

Critics of the proposed bicycle lanes on Grant Avenue warn that the lanes will slow traffic for everyone. But the city's engineers found that the avenue's congestion comes almost entirely from cars turning left across oncoming traffic, and the lane design includes dedicated left-turn signals that would remove that cause. Far from slowing traffic, then, the new lanes are likely to speed it up.

Which one of the following most accurately expresses the main conclusion of the argument?

AMost congestion on Grant Avenue is caused by cars turning left across oncoming traffic.
BThe proposed bicycle lanes will slow traffic for everyone on Grant Avenue.
CBicycle lanes tend to speed up traffic on busy city streets.
DThe proposed lanes are likely to make traffic on Grant Avenue move faster rather than slower.
EThe design of the proposed lanes includes dedicated left-turn signals.
