Input: Article: In 1877, John Wanamaker opened the United State's first modern department store in a former Pennsylvania Railroad freight terminal in Philadelphia. Wanamakers was the first department store to offer fixed prices marked on every article and also introduced electrical illumination (1878), the telephone (1879), and the use of pneumatic tubes to transport cash and documents (1880) to the department store business. Subsequent department stores founded in Philadelphia included Strawbridge and Clothier, Gimbels, Lit Brothers, and Snellenbergs.

Now answer this question: When was electric lighting first installed and used in the store? 

Output: 1878

Input: Article: In practice, not all rule violations will result in a disqualification as the referee may use their own judgement and is not obligated to stop the match. Usually, the only offenses that the referee will see and immediately disqualify the match on (as opposed to having multiple offenses) are low blows, weapon usage, interference, or assaulting the referee. In WWE, a referee must see the violation with their own eyes to rule that the match end in a disqualification (simply watching the video tape is not usually enough) and the referee's ruling is almost always final, although Dusty finishes (named after, and made famous by, Dusty Rhodes) will often result in the referee's decision being overturned. It is not uncommon for the referees themselves to get knocked out during a match, which is commonly referred to by the term "ref bump". While the referee remains "unconscious", wrestlers are free to violate rules until the referee is revived or replaced. In some cases, a referee might disqualify a person under the presumption that it was that wrestler who knocked them out; most referee knockouts are arranged to allow a wrestler, usually a heel, to gain an advantage. For example, a wrestler may get whipped into a referee at a slower speed, knocking the ref down for short amount of time; during that interim period, one wrestler may pin their opponent for a three-count and would have won the match but for the referee being down (sometimes, another referee will sprint to the ring from backstage to attempt to make the count, but by then, the other wrestler has had enough time to kick-out on their own accord).

Now answer this question: What can wrestlers do when a ref is out? 

Output: free to violate rules

Input: Article: The CIA had different demands placed on it by the different bodies overseeing it. Truman wanted a centralized group to organize the information that reached him, the Department of Defense wanted military intelligence and covert action, and the State Department wanted to create global political change favorable to the US. Thus the two areas of responsibility for the CIA were covert action and covert intelligence. One of the main targets for intelligence gathering was the Soviet Union, which had also been a priority of the CIA's predecessors.

Now answer this question: Who wanted the CIA to have a central group that organized information for him?

Output:
Truman
