Input: Read this: Caray had lively discussions with commentator Steve Stone, who was hand-picked by Harry himself, and producer Arne Harris. Caray often playfully quarreled with Stone over Stone's cigar and why Stone was single, while Stone would counter with poking fun at Harry being "under the influence." Stone disclosed in his book "Where's Harry" that most of this "arguing" was staged, and usually a ploy developed by Harry himself to add flavor to the broadcast. The Cubs still have a "guest conductor", usually a celebrity, lead the crowd in singing "Take me out to the ballgame" during the 7th inning stretch to honor Caray's memory.
Question: Who did Harry hand-pick himself?

Output: Steve Stone


Input: Read this: Moisture absorption occurs when the material is exposed to high humidity or water. Both the resin and the reinforcement may absorb water; water may be also soaked by capillary forces through voids in the materials and along the reinforcement. Epoxies of the FR-4 materials aren't too susceptible, with absorption of only 0.15%. Teflon has very low absorption of 0.01%. Polyimides and cyanate esters, on the other side, suffer from high water absorption. Absorbed water can lead to significant degradation of key parameters; it impairs tracking resistance, breakdown voltage, and dielectric parameters. Relative dielectric constant of water is about 73, compared to about 4 for common circuitboard materials. Absorbed moisture can also vaporize on heating and cause cracking and delamination, the same effect responsible for "popcorning" damage on wet packaging of electronic parts. Careful baking of the substrates may be required.
Question: Repelled water can lead to what?

Output: unanswerable


Input: Read this: The U.S. Eisenhower administration condemned the tripartite invasion, and supported UN resolutions demanding withdrawal and a United Nations Emergency Force (UNEF) to be stationed in Sinai. Nasser commended Eisenhower, stating he played the "greatest and most decisive role" in stopping the "tripartite conspiracy". By the end of December, British and French forces had totally withdrawn from Egyptian territory, while Israel completed its withdrawal in March 1957 and released all Egyptian prisoners of war. As a result of the Suez Crisis, Nasser brought in a set of regulations imposing rigorous requirements for residency and citizenship as well as forced expulsions, mostly affecting British and French nationals and Jews with foreign nationality, as well as some Egyptian Jews.
Question: What country was opposed to the invasion of the canal?

Output: U.S.


Input: Read this: Due to the work nature of airline pilots, who often cross several timezones and regions of sunlight and darkness in one day, and spend many hours awake both day and night, they are often unable to maintain sleep patterns that correspond to the natural human circadian rhythm; this situation can easily lead to fatigue. The NTSB cites this as contributing to many accidents[unreliable medical source?]  and has conducted several research studies in order to find methods of combating fatigue in pilots.
Question: Who follows a very natural human circadian rhythem?

Output:
unanswerable
