A system that combines radar and infrared can be installed in cargo ships and passenger liners to provide a ship’s crew with a warning if another vessel is in the shipping lane directly ahead. The early warning allows a ship’s captain to attempt an abrupt course change to avert a possible collision. Even though cargo ships and passenger liners need a considerable distance to maneuver and that most warnings are false, such an early warning system undoubtedly better protects cargo and passengers.
Which one of the following, if true, most strengthens the argument?
A. The system can detect not only the physical presence of a ship by radar but it can also detect a ship's heat signature by infrared.
B. A maritime safety commission report determined that over 82% of the system’s warnings were false.
C. Ship collisions in the major oceanic shipping lanes are extremely rare.
D. The risk of a cargo ship or passenger liner being involved in a collision is substantially greater at port than at sea.
E. Abrupt course changes do not involve risk to a ship’s cargo or passengers.
