Passage 76.   Since 1965, when its equipment became operational, a device called Eros has been helping to make sky traffic safe. Eros is short for Eliminate Range Zero System range zero meaning collision. Basically Eros is a computer system that measures, with great speed and precision, closing speed (the speed at which two objects are approaching each other) and range (the distance apart of the objects). Eros can warn aircraft approaching each other at jet speeds and can provide protection for as many as a thousand aircraft in a wide area. The pilot of an Eros-equipped aircraft heading for a collision hears a warning noise in his earphones when his airborne computer calculates that he is within thirty seconds or half a mile (whichever occurs first) of another aircraft. At the same time, a flashing red arrow on the device's indicator panel instructs him to descend. Simultaneously, in the other aircraft, the signal is automatically reversed: the flashing arrow tells the pilot to climb. The newer Eros 11 system can accommodate a total of two thousand aircraft at one time within a 140-mile radius. Every three seconds, each Eros-equipped plane automatically reports to ground stations and to similarly equipped aircraft its precise range, altitude, and approach rate. The producers of Eros, the McDonnell Douglas Corporation in the United States, are now studying the fitting of Eros collision-avoidance systems in all sizes and types of aircraft. Automatic systems such as Eros will do more than make the sky safer: they will also lighten the work of air-traffic controllers and increase the efficiency of airports.   Mark the best choice       1. The o in the acronym Eros represents __________.
