　　Tuning In During the Twenties

　　[1]

　　Modern broadcasting began to develop after

　　the First World War. Before 1920, radio was simply

　　a useful way to send electrical signals ashore from aship at sea, or, from one "ham" operator to another.

　　The new technology associated with movies and

　　airplanes was already developing rapidly by the time

　　soldiers started returning from European trenchesin 1918. The vast potential of the airwaves, therefore,

　　had scarcely been touched.

　　[2]

　　[1] Then a vice president of Westinghouse,

　　looking for a way to make the transmission of radiosignals more profitable, decided on a two-fold

　　strategy. [2] First, he would entice an audience with

　　daily programming of great variety. [3] Second, he

　　would sell this audience the radio receivers necessaryto listen to this entertainment. [4] Theplan succeededbeyond anyone's expectations.

　　[3]

　　The federal Radio Division in Washington, D.C.,was created to license stations, because it had no

　　power to regulate them. Broadcasters multiplied

　　wildly, some helping themselves to the more desirable

　　frequencies, others increasing their transmissionpower at will. Chaos means things were out of control.

　　[4]

　　Yet even in the midst of such anarchy,some commercial possibilities and organizations

　　saw clearly of a medium whose regulation seemed

　　imminent. In 1926, RCA paid the American

　　Telephone & Telegraph Company one million dollars

　　for station WEAF in New York City—and NBC wasborn. Years later, the Radio Law of 1927 wasenacted. It authorized it's control forlicensing and of policing the broadcasters.

　　[5]

　　The RCA executives who created the

　　powerful NBC network were right to see that

　　sizable profits would come from this new medium.Even in 1930 for example an hour's advertising on

　　nationwide radio to forty-seven cities cost $10,180.

　　Advertising turned broadcasting into an industry,

　　and the untapped potential of the airwavesbegan to be realized.

　—————————————————————————————————————————————————

　　Choose the best alternative for the underlined part 11.

　　A. NO CHANGE

　　B. which

　　C. having

　　D. as

　　謎底：A

　　【剖析】The best answer is A, which proposes the correct relative pronoun to link the subject of the sentence ("the RCA executives") with the clause that describes the subject ("who created 　　the powerful NBC network"). Choice B uses which, a relative pronoun that is used to refer to things, not persons. Choice C creates a gerund phrase that would need to be set off by commas. Choice D creates both faulty logic and faulty subordination.
