Input: Read this: Many television shows and films have been produced which portray in-character professional wrestlers as protagonists, such as Ready to Rumble, ¡Mucha Lucha!, Nacho Libre, and the Santo film series. In the wildly popular Rocky series of films about the fictional boxer Rocky Balboa, Rocky III saw its hero fighting a "boxer vs. wrestler" exhibition match against the enormous and villainous wrestler "Thunderlips", portrayed by real-life soon-to-be wrestling icon Hulk Hogan. At least two stage plays set in the world of pro wrestling have been produced: The Baron is a comedy that retells the life of an actual performer known as Baron von Raschke. From Parts Unknown... is an award-nominated Canadian drama about the rise and fall of a fictional wrestler. The 2009 South Park episode "W.T.F." played on the soap operatic elements of professional wrestling. One of the lead characters on the Disney Channel series Kim Possible was a huge fan of pro wrestling and actually featured it on an episode (with two former WWE wrestlers voicing the two fictitious wrestlers featured in the episode). The 2008 film The Wrestler, about a washed-up professional wrestler, garnered several Oscar nominations.
Question: Many of what forms of entertainment have portrayed wrestlers? 

Output: television shows and films


Input: Read this: Heartwood (or duramen) is wood that as a result of a naturally occurring chemical transformation has become more resistant to decay. Heartwood formation occurs spontaneously (it is a genetically programmed process). Once heartwood formation is complete, the heartwood is dead. Some uncertainty still exists as to whether heartwood is truly dead, as it can still chemically react to decay organisms, but only once.
Question: What is heartwood naturally resistant to?

Output: decay


Input: Read this: However, memory performance can be enhanced when material is linked to the learning context, even when learning occurs under stress. A separate study by cognitive psychologists Schwabe and Wolf shows that when retention testing is done in a context similar to or congruent with the original learning task (i.e., in the same room), memory impairment and the detrimental effects of stress on learning can be attenuated. Seventy-two healthy female and male university students, randomly assigned to the SECPT stress test or to a control group, were asked to remember the locations of 15 pairs of picture cards – a computerized version of the card game "Concentration" or "Memory". The room in which the experiment took place was infused with the scent of vanilla, as odour is a strong cue for memory. Retention testing took place the following day, either in the same room with the vanilla scent again present, or in a different room without the fragrance. The memory performance of subjects who experienced stress during the object-location task decreased significantly when they were tested in an unfamiliar room without the vanilla scent (an incongruent context); however, the memory performance of stressed subjects showed no impairment when they were tested in the original room with the vanilla scent (a congruent context). All participants in the experiment, both stressed and unstressed, performed faster when the learning and retrieval contexts were similar.
Question: In their study what was the relationship that both groups shared?

Output: both stressed and unstressed, performed faster when the learning and retrieval contexts were similar.
