Red-light cameras, originally implemented
in an attempt at increasing the safety of intersections, have been precisely the opposite: drivers are afraid of expensive citations and often brake suddenly as they approach camera-equipped intersections, so they cause rear-end accidents.

OFFICIAL EXPLANATION FROM MANHATTAN PREP:The language
in an attempt at increasing the safety of intersections illogically implies that the cameras were conceived to keep the intersections themselves safe, rather than to ensure the safety of drivers and others at those intersections. Further, the first clause states that
the cameras... have been precisely the opposite but the sentence doesn't indicate the opposite of what. Find a choice that conveys a logical
Meaning (in this case that the cameras have had the opposite
effect than what was originally intended - they cause, rather than prevent, accidents).
(A) This choice is incorrect for the reasons stated above.
(B) The construction
while attempting… refers to the subject of the main clause (red-light cameras). In this case, that creates a nonsensical meaning: that the cameras themselves were in the process of
attempting to increase safety.
(C) The construction
in attempting… refers to the subject of the main clause. In this case, that creates a nonsensical meaning: that the cameras themselves were in the process of
attempting to increase safety. The sentence places
fear, approach, brake, and
cause in parallel. While grammatically correct in a superficial sense, this parallelism doesn't make logical sense, because these verbs don't represent four separate actions of the same type or in the same context. Rather, the four represent a particular sequence of events: drivers are afraid of citations, so they break suddenly when approaching these intersections,
leading to accidents.
(D) The opening of this version describes the cameras themselves as
attempts to increase … safety. However, the
usage of the cameras was an attempt to increase safety, not the mere existence of the cameras. In addition, the first clause states that the cameras themselves
are precisely the opposite, but the sentence doesn't indicate the opposite of what. Find a choice that conveys a logical meaning (in this case that the cameras have had the opposite
effect than what was originally intended - they cause, rather than prevent, accidents). Finally, in the second clause,
afraid of expensive citations modifies
drivers approach, thus illogically suggesting that the fear of receiving a ticket influences the drivers' decision to approach the intersections in the first place (as opposed to influencing what they do once they reach those intersections).
(E) CORRECT. The modifier
in an attempt to increase safety at intersections describes the situation logically: the intent was to increase general safety in this area.
Precisely is correctly placed in front of the
opposite effect.
Fearing expensive citations is properly used to describe drivers approaching camera-equipped intersections and provides a cause for the actions following. Finally, the comma +
causing rear-end accidents construction is properly used to describe an immediate consequence of the action in the preceding clause.
