Q: Question: Who was head of the DOJ during Duffy's service as an Assistant United States Attorney? Passage 1:Born on January 10, 1933, in New York City, New York, Duffy received an Artium Baccalaureus degree from Fordham University in 1954 and a Bachelor of Laws from the Fordham University School of Law in 1958. He clerked for Judge J. Edward Lumbard at the United States Court of Appeals for the Second Circuit (1955–1958). Duffy served as an Assistant United States Attorney (1958–1959) and assistant chief of the Criminal Division (1959–1961) at the office of the United States Attorney for the Southern District of New York before going into private practice as an associate with the New York City firm Whitman, Ransom & Coulson (1961–1966). He later became a partner with Gordon & Gordon (1966–1969). Duffy later appointed New York regional administrator of the Securities and Exchange Commission office (1969–1972). His tenure as Regional Administrator of the United States Securities and Exchange Commission was in a time of turmoil in Wall Street. He is viewed by many as having been the first proponent within the Commission of what eventually became Securities Investor Protection Corporation or SIPC.
 Passage 2:During the past decade, Rialto Pictures has become one of the great names in film distribution. In 2002, the company released the critically acclaimed first-run film Murderous Maids, the chilling true story of two homicidal sisters, starring Sylvie Testud. Rialto celebrated a record-breaking 2004 with the previously unreleased, original 1954 Japanese version of Ishiro Honda’s Godzilla; Peter Davis’s Oscar-winning and newly restored 1974 documentary Hearts and Minds; and Gillo Pontecorvo’s groundbreaking The Battle of Algiers, one of 2004’s top-grossing foreign films. Rialto’s re-release of Alberto Lattuada’s Mafioso, a dark comedy from 1962 starring Alberto Sordi, was the unqualified highlight of the 2006 New York Film Festival. One of Rialto’s 2008 releases was Max Ophüls' legendary film Lola Montès in a definitive new 35mm restoration, which was showcased to enormous acclaim at Cannes Film Festival and Telluride Film Festival and was the spotlight retrospective of the 2008 New York Film Festival. In 2009, Rialto undertook the very first U.S. release of Jean-Luc Godard's Made in U.S.A., which could not be previously released due to rights issues, and also re-released Costa-Gavras' Academy Award-winning thriller Z. Most recently, the San Francisco International Film Festival presented Goldstein with its prestigious Mel Novikoff Award.
 Passage 3:The discovery of the triode's amplifying ability in 1912 revolutionized electrical technology, creating the new field of electronics, the technology of active (amplifying) electrical devices. The triode was immediately applied to many areas of communication. Triode "continuous wave" radio transmitters replaced the cumbersome inefficient "damped wave" spark gap transmitters, allowing the transmission of sound by amplitude modulation (AM). Amplifying triode radio receivers, which had the power to drive loudspeakers, replaced weak crystal radios, which had to be listened to with earphones, allowing families to listen together. This resulted in the evolution of radio from a commercial message service to the first mass communication medium, with the beginning of radio broadcasting around 1920. Triodes made transcontinental telephone service possible. Vacuum tube triode repeaters, invented at Bell Telephone after its purchase of the Audion rights, allowed telephone calls to travel beyond the unamplified limit of about 800 miles. The opening by Bell of the first transcontinental telephone line was celebrated 3 years later, on January 25, 1915. Other inventions made possible by the triode were television, public address systems, electric phonographs, and talking motion pictures.
