Question: What did NBC delay for the west coast primetime?, Context: CBC's sports coverage has also attained high viewership in border markets, including its coverage of the NHL's Stanley Cup Playoffs, which was generally considered to be more complete and consistent than coverage by other networks such as NBC. Its coverage of the Olympic Games also found a significant audience in border regions, primarily due to the fact that CBC aired more events live than NBC's coverage, which had been criticized in recent years for tape delaying events to air in primetime, even if the event is being held in a market in the Pacific Time Zone during primetime hours on the East (where it would still be delayed for West coast primetime).

Answer: Olympic Games


Question: What would an engine driver have to do to adjust the more modern type of valve?, Context: Steam engines frequently possess two independent mechanisms for ensuring that the pressure in the boiler does not go too high; one may be adjusted by the user, the second is typically designed as an ultimate fail-safe. Such safety valves traditionally used a simple lever to restrain a plug valve in the top of a boiler. One end of the lever carried a weight or spring that restrained the valve against steam pressure. Early valves could be adjusted by engine drivers, leading to many accidents when a driver fastened the valve down to allow greater steam pressure and more power from the engine. The more recent type of safety valve uses an adjustable spring-loaded valve, which is locked such that operators may not tamper with its adjustment unless a seal illegally is broken. This arrangement is considerably safer.[citation needed]

Answer: seal illegally is broken


Question: Who was President during the Eisenhower Administration?, Context: On May 1, 1960, a U.S. one-man U-2 spy plane was reportedly shot down at high altitude over Soviet Union airspace. The flight was made to gain photo intelligence before the scheduled opening of an East–West summit conference, which had been scheduled in Paris, 15 days later. Captain Francis Gary Powers had bailed out of his aircraft and was captured after parachuting down onto Russian soil. Four days after Powers disappeared, the Eisenhower Administration had NASA issue a very detailed press release noting that an aircraft had "gone missing" north of Turkey. It speculated that the pilot might have fallen unconscious while the autopilot was still engaged, and falsely claimed that "the pilot reported over the emergency frequency that he was experiencing oxygen difficulties."

Answer:
Eisenhower
