Example Input: According to Genius, the James Gleick-authored biography, Feynman tried LSD during his professorship at Caltech. Somewhat embarrassed by his actions, he largely sidestepped the issue when dictating his anecdotes; he mentions it in passing in the "O Americano, Outra Vez" section, while the "Altered States" chapter in Surely You're Joking, Mr. Feynman! describes only marijuana and ketamine experiences at John Lilly's famed sensory deprivation tanks, as a way of studying consciousness. Feynman gave up alcohol when he began to show vague, early signs of alcoholism, as he did not want to do anything that could damage his brainthe same reason given in "O Americano, Outra Vez" for his reluctance to experiment with LSD.
Example Output: What substance did Feynman give up later in life?

Example Input: Bell's own home used a primitive form of air conditioning, in which fans blew currents of air across great blocks of ice. He also anticipated modern concerns with fuel shortages and industrial pollution. Methane gas, he reasoned, could be produced from the waste of farms and factories. At his Canadian estate in Nova Scotia, he experimented with composting toilets and devices to capture water from the atmosphere. In a magazine interview published shortly before his death, he reflected on the possibility of using solar panels to heat houses.
Example Output: What form of water played a part in Bell's home cooling system?

Example Input: The variant forms of the name of the Rhine in modern languages are all derived from the Gaulish name Renos, which was adapted in Roman-era geography (1st century BC) as Greek (Rhenos), Latin Rhenus.[note 3] The spelling with Rh- in English Rhine as well as in German Rhein and French Rhin is due to the influence of Greek orthography, while the vocalisation -i- is due to the Proto-Germanic adoption of the Gaulish name as *Rinaz, via Old Frankish giving Old English Rin, Old High German Rin, Dutch Rijn (formerly also spelled Rhijn)). The diphthong in modern German Rhein (also adopted in Romansh Rein, Rain) is a Central German development of the early modern period, the Alemannic name Ri(n) retaining the older vocalism,[note 4] as does Ripuarian Rhing, while Palatine has diphthongized Rhei, Rhoi. Spanish is with French in adopting the Germanic vocalism Rin-, while Italian, Occitan and Portuguese retain the Latin Ren-.
Example Output:
Where does the name Rhine derive from?
