A proposed rule requires the installation of guardrails on all traffic bridges in the state of Willericka. However, an engineer argued that because traffic accidents on bridges account for only 2 percent of all traffic accidents in Willericka, guardrails would do little to reduce the number of traffic injuries.
Which of the following, if true, would most seriously weaken the engineer’s argument?
A) Most drivers are ill-equipped to drive on bridges.
B) Since only a small portion of the state contains many bridges, the new rule would primarily affect that area.
C) The installation of warning signs on bridges costs significantly less than the installation of guardrails.
D) Willericka is known for its excellent emergency first responder services.
E) Traffic accidents occurring on bridges account cause significantly more injuries than those occurring anywhere else.
