[EX Q]: Passage: In May 1944, as the war began to turn in favor of the Allies, WCBW reopened the studios and the newscasts returned, briefly anchored by Ned Calmer, and then by Everett Holles. After the war, expanded news programs appeared on the WCBW schedule - whose call letters were changed to WCBS-TV in 1946 - first anchored by Milo Boulton, and later by Douglas Edwards. On May 3, 1948, Edwards began anchoring CBS Television News, a regular 15-minute nightly newscast on the CBS television network, including WCBS-TV. It aired every weeknight at 7:30 p.m., and was the first regularly scheduled, network television news program featuring an anchor . NBC's offering at the time, NBC Television Newsreel , was simply film footage with voice narration. In 1950, the name of the nightly newscast was changed to Douglas Edwards with the News, and the following year, it became the first news program to be broadcast on both coasts, thanks to a new coaxial cable connection, prompting Edwards to use the greeting "Good evening everyone, coast to coast." The broadcast was renamed the CBS Evening News when Walter Cronkite replaced Edwards in 1962. Edwards remained with CBS News with various daytime television newscasts and radio news broadcasts until his retirement on April 1, 1988. 
Question: How many years did Edwards remain with CBS News before he retired in 1988?

[EX Q]: Passage: After World War I, public opinion in the United States began to run against the occupation. Warren G. Harding, who succeeded Wilson in March 1921, had campaigned against the occupations of both Haiti and the Dominican Republic. In June 1921, United States representatives presented a withdrawal proposal, known as the Harding Plan, which called for Dominican ratification of all acts of the military government, approval of a loan of $2.5 million USD for public works and other expenses, the acceptance of United States officers for the constabulary—now known as the National Guard —and the holding of elections under United States supervision. Popular reaction to the plan was overwhelmingly negative. Moderate Dominican leaders, however, used the plan as the basis for further negotiations that resulted in an agreement between U.S. Secretary of State Charles Evans Hughes and Dominican Ambassador to the United States Francisco J. Peynado on June 30, 1922, allowing for the selection of a provisional president to rule until elections could be organized. Under the supervision of High Commissioner Sumner Welles, Juan Bautista Vicini Burgos assumed the provisional presidency on October 21, 1922. In the presidential election of March 15, 1924, Horacio Vásquez Lajara, an American ally who cooperated with the United States government, handily defeated Peynado. Vásquez's Alliance Party  also won a comfortable majority in both houses of Congress. With his inauguration on July 13, control of the republic returned to Dominican hands. 
Question: How many years was the provisional president in charge for?
