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?

Q: Passage: The Mataram conquest of Surabaya or Mataram-Surabaya War was a military campaign by the Sultanate of Mataram in the early 17th century that resulted in the capture of the Duchy of Surabaya  and its allies in eastern Java, in modern-day Indonesia. Prior to this conquest, Mataram and Surabaya were rivals for power in central and eastern Java. The campaign began in 1614 when Mataram, under the leadership of Sultan Agung, attacked Surabaya's allies, including Wirasaba. Surabaya and its allies launched a counterattack but were defeated near Pajang in 1616. Over the next few years, Mataram gradually conquered members of the Surabayan alliance, and by 1620, the city of Surabaya itself was under siege, holding out until it surrendered in 1625. With this conquest, Mataram unified most of central and eastern Java under its control, and cemented its position as the dominant power in Java. Surabaya and other conquered areas would remain in Mataram's hands until it was ceded to the Dutch East India Company in 1743. 
Question: How many years from the beginning of Mataram's campaign did it take for the city of Surabaya to surrender? 
Answer type: Number 

A: 11.
