Problem:Question: Who directed Calhern in his role as the devious George Caswell? Passage 1:Born in Arlington County, Virginia, Purcell earned her bachelor's degree in painting from the Corcoran School of Art and George Washington University in 1973, after independent study in Mexico from 1969 to 1971. In 1995 she received a Master of Arts degree in Liberal Studies from New York University. She has been invited to many exhibitions, solo and group, both in the United States and abroad. An abstract expressionist, she received a Pollock-Krasner Foundation grant in 1989 and in 2018; a Lester Hereward Cooke foundation grant for mid-career achievement in painting in 1988 associated through The National Gallery of Art, Wash., D.C.; a fellowship at the MacDowell Colony in 1975; and grants from the New York Foundation for the Arts in 2013, the Joan Mitchell Foundation in 2014, and the Adolph and Esther Gottlieb Foundation in 2014. She has been a guest lecturer at Indiana State University, the Smithsonian American Art Museum, and Long Island University, and was on the faculty of the Corcoran School of Art and the Smithsonian Institution from 1974 to 1979; from 1983 to 1985 she taught at the Parsons School of Design. Museums which own examples of Purcell's work includejThe National Gallery of Art, the Phillips Collection, the Corcoran Museum of Art, the National Museum of Women in the Arts, the Santa Barbara Museum of Art, the New Orleans Museum of Art, the Virginia Museum of Fine Arts, and the Salt Lake City Museum, and it may be found in numerous private and corporate collections as well. She is currently represented by the prestigious Berry Campbell Gallery in New York City. Her works and more information can be viewed at www.annpurcellart.com.
 Passage 2:In 1923, Calhern left the movies, deciding to devote his career entirely to the stage, but he would later return to the screen after the advent of sound pictures. In films, He was primarily cast as a character actor, while he continued to play leading roles on the stage. He reached his peak in the early 1950s as a Metro-Goldwyn-Mayer contract player. Among Calhern's many memorable screen portrayals were Ambassador Trentino in the Marx Brothers classic Duck Soup (1933) and three diverse roles that he appeared in at MGM in 1950: a singing role as Buffalo Bill in the film version of the musical Annie Get Your Gun, as a double-crossing lawyer and sugar-daddy to Marilyn Monroe in John Huston's film noir classic The Asphalt Jungle, and his Oscar-nominated performance as Oliver Wendell Holmes in The Magnificent Yankee (re-creating his role from the Broadway stage). He was also praised for his portrayal of the title role in the John Houseman production of Julius Caesar (adapted from the Shakespeare play) in 1953, directed by Joseph L. Mankiewicz. Calhern also played the role of the devious George Caswell, the manipulative board member of Tredway Corporation in the 1954 production of Executive Suite.
 Passage 3:A modulated radio wave, carrying an information signal, occupies a range of frequencies. See diagram. The information (modulation) in a radio signal is usually concentrated in narrow frequency bands called sidebands (SB) just above and below the carrier frequency. The width in hertz of the frequency range that the radio signal occupies, the highest frequency minus the lowest frequency, is called its bandwidth (BW). A given amount of bandwidth can carry the same amount of information (data rate in bits per second) regardless of where in the radio frequency spectrum it is located, so bandwidth is a measure of information-carrying capacity. The bandwidth required by a radio transmission depends on the data rate of the information (modulation signal) being sent, and the spectral efficiency of the modulation method used; how much data it can transmit in each kilohertz of bandwidth. Different types of information signals carried by radio have different data rates. For example, a television (video) signal has a greater data rate than an audio signal.
