Text I (Questions 13-17)

Radio, envisioned by its inventor as a great humanitarian contribution, was seized upon by the generals soon after its birth in 1895 and impressed as an instrument of war. For it immeasurably magnified the chief military advantage of telegraphy: instantaneous control of an entire army by a single commander. By eliminating the need for physical linkage by wire, radio speeded communication between headquarters, joined through the 5 other units that could not connect by wire because of distance, terrain, hostile forces, or rapid movement, opened communications with naval and air forces, and eased the economic burden of producing immense quantities of wire. But few blessings are unmixed. Just as the telegraph had made military communications much more effective but had also increased the possibility of 10 interception over that of hand-carried dispatches, so radio's vast amplification of military communications was accompanied by an enormously greater probability of interception. The public, omnidirectional nature of radio transmissions, which makes wireless communication so easy to establish, makes it equally easy to intercept. It was no longer necessary to gain physical access to a telegraph line behind the enemy's front to 15 eavesdrop upon his communications. A commander had only to sit in his headquarters and tune his radio to the enemy's wavelength. Radio thereupon introduced two revolutionary factors in the interception of communications: volume and continuity.
