1921本题考查考生对于具体信息的听辨能力。从“Born in New York on May 21，1921， Mr．Migden graduated from Columbia Law School in l947”可知答案。

Chester L. Migden, a lawyer whose work for the Screen Actors Guild helped to establish the principle of paying actors for repeat showings of the television programs, feature films and commercials they appear in—a practice that produces nearly ＄1 billion today—died on Sunday at his home in Los Angeles. He was 78. Born in New York on May 21, 1921, Mr. Migden graduated from Columbia Law School in 1947 and became a staff attorney for the National Labor Relations Board in New York. He soon joined the Guild in Los Angeles.
     As recently as the 1970’s, when the weekly minimum wage for actors was about＄1,200, they received little or no compensation for multiple usage of their appearances. In contract negotiations, Mr. Migden argued that actors should receive a fair share of the revenue generated not only by free television or first-time theatrical usage but by reruns and supplemental markets like video cassettes and disks, and basic and pay cable television. Ken Orsatti, the Guild’s national executive director, said that the contracts negotiated under Mr. Migden, who served as director from 1952 to 1982, "improved the lot of actors a dozen times over."
     After retiring in 1982, Mr. Migden became executive director of the Association of Talent Agents, a position he held until his retirement in 1996.
