[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: Coming off back-to-back losses in overtime, the Steelers looked to turn things around.  With the return of Ben Roethlisberger to action, the Steelers hosted the 3-8 Oakland Raiders. The Steelers would open with a 33-yard field goal by Jeff Reed.  Oakland responded with a 48-yarder by Sebastian Janikowski, and both teams were tied 3-3 as the 2nd quarter began.  Roethlisberger found Santonio Holmes for a 34-yard TD pass to begin the 2nd quarter.  Oakland would put 3 points on the board after a 43-yard field goal halfway through the quarter, and the Steelers headed to Halftime with a 10-6 lead. There followed a scoreless third quarter, and in the fourth Pittsburgh's defensive struggles were exploited by the Raiders, who were able to find the end zone three times. Bruce Gradkowski would find Chaz Schilens for a 17-yard TD pass with 8:21 remaining in the game, giving Oakland their first lead of the game, 13-10. Pittsburgh responded just one minute later with a 3-yard TD run by Rashard Mendenhall.  But Oakland would not be stopped.  Gradkowski hit Louis Murphy for a 75-yard TD pass with 5:28 remaining, and the Raiders went up 20-17. Roethlisberger would make an 11-yard TD pass to Hines Ward with 1:56 remaining and the Steelers would regain the lead 24-20.  All that was needed was for the Steelers' defense to keep Oakland out of the end zone and they would win. But with nine seconds remaining, Gradkowski would once again find Louis Murphy open in the end zone for an 11-yard TD pass and the Raiders would win 27-24. The game would mark the fifth time in six games that the Steelers suffered a 4th quarter collapse, and the second time in three weeks Pittsburgh had fallen to an opponent with a losing record. At the conclusion of the game, the Steelers had allowed seven plays of 40&#160;yards or longer in their last four games (they only gave up two such plays in 2008). 
Question: How many points were the Steelers winning by during halftime? 
Answer type: Number 
[EX A]: 4.

[EX Q]: Passage: The War of the Polish Succession again called him into the field. In 1733, Lacy and Munnich expelled the Polish king, Stanisław I, from Warsaw to Danzig, which was besieged by them in 1734. Thereupon the Irishman was commanded to march towards the Rhine and join his 13,500-strong contingent with the forces of Eugene of Savoy. To that end his corps advanced into Germany and, meeting the Austrians on 16 August, returned to winter quarters in Moravia with exemplary discipline. Lacy had reached the rank of Field Marshal with the outbreak of the Russo-Turkish War, in which his success exceeded even the most unreasonable expectations. In 1736 he was in charge of the Don Army which took the key citadel of Azov, and in the next year his corps crossed the Syvash marshes into Crimea, where he fell upon the 15,000-strong Crimean army and routed them in two battles, on 12 and 14 June. In 1738, Lacy's corps again landed in Crimea and took the fortress of Çufut Qale near the Khan's capital, Bakhchisaray. As soon as peace had been restored, Lacy was reinstated as the Governor of Livland, while Emperor Charles VI conferred on him the title of imperial count. His indifference to politics prevented his downfall following Anna's death, when other foreign commanders fell into disgrace and were expelled from active service. 
Question: How many years after the Polish king was expelled did Lacy's corps take the fortress of Çufut Qale?
