OFFICIAL EXPLANTIONSituation: The author says that the number of accidents have come down since
certain rules have been made strict.
Reasoning: What could possibly strengthen the argument? A statement that supports
the fact that the reduced movement of trucks on fly-overs has led to a decrease in accidents.
Something that connects the two directly would help in bringing forth this fact.
(A) More people wearing helmets now could be a reason for the reduction of accidents but that doesn't justify the fact that the movement of those people is through the fly-overs alone.
(B) The goods falling isn't a direct indication of the fact that accidents have been reduced.
(C) CORRECT. This correctly explains that as drivers don't apply sudden brakes, bikes don't skid. This means that accidents there (over the fly-overs) are fewer.
(D) Blocks could be a major cause of traffic jams, not accidents.
(E) Stress or damage to the fly-overs cause it to collapse but that is a very rare occurrence. Moreover, fly-overs are built to accommodate heavy vehicles. They
aren't prone to break-down if a heavy vehicle passes over them.
Choice (C) is the correct answer
