Problem: 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 brain—the same reason given in "O Americano, Outra Vez" for his reluctance to experiment with LSD.
Why did Feynman give up alcohol?
The answer is the following: he did not want to do anything that could damage his brain

Problem: The transition from hunting and gathering to agriculture is not necessarily a one way process. It has been argued that hunting and gathering represents an adaptive strategy, which may still be exploited, if necessary, when environmental change causes extreme food stress for agriculturalists. In fact, it is sometimes difficult to draw a clear line between agricultural and hunter-gatherer societies, especially since the widespread adoption of agriculture and resulting cultural diffusion that has occurred in the last 10,000 years.[citation needed] This anthropological view has remained unchanged since the 1960s.[clarification needed][citation needed]
How long has this cultural diffusion been happening?
The answer is the following: last 10,000 years

Problem: Schwarzenegger drew attention and boosted his profile in the bodybuilding film Pumping Iron (1977), elements of which were dramatized; in 1991, he purchased the rights to the film, its outtakes, and associated still photography. In 1977, he also appeared in an episode of the ABC situation comedy The San Pedro Beach Bums. Schwarzenegger auditioned for the title role of The Incredible Hulk, but did not win the role because of his height. Later, Lou Ferrigno got the part of Dr. David Banner's alter ego. Schwarzenegger appeared with Kirk Douglas and Ann-Margret in the 1979 comedy The Villain. In 1980, he starred in a biographical film of the 1950s actress Jayne Mansfield as Mansfield's husband, Mickey Hargitay.
When did Schwarzenegger purchase the rights to the film Pumping Iron?
The answer is the following: 1991

Problem: Based on earlier transmitted reports, in the year 632, after the demise of Muhammad a number of his companions who knew the Quran by heart were killed in a battle by Musaylimah, the first caliph Abu Bakr (d. 634) decided to collect the book in one volume so that it could be preserved. Zayd ibn Thabit (d. 655) was the person to collect the Quran since "he used to write the Divine Inspiration for Allah's Apostle". Thus, a group of scribes, most importantly Zayd, collected the verses and produced a hand-written manuscript of the complete book. The manuscript according to Zayd remained with Abu Bakr until he died. Zayd's reaction to the task and the difficulties in collecting the Quranic material from parchments, palm-leaf stalks, thin stones and from men who knew it by heart is recorded in earlier narratives. After Abu Bakr, Hafsa bint Umar, Muhammad's widow, was entrusted with the manuscript. In about 650, the third Caliph Uthman ibn Affan (d. 656) began noticing slight differences in pronunciation of the Quran as Islam expanded beyond the Arabian Peninsula into Persia, the Levant, and North Africa. In order to preserve the sanctity of the text, he ordered a committee headed by Zayd to use Abu Bakr's copy and prepare a standard copy of the Quran. Thus, within 20 years of Muhammad's death, the Quran was committed to written form. That text became the model from which copies were made and promulgated throughout the urban centers of the Muslim world, and other versions are believed to have been destroyed. The present form of the Quran text is accepted by Muslim scholars to be the original version compiled by Abu Bakr.
Which caliph ordered the Quran manuscript copied and standardized?
The answer is the following:
Uthman ibn Affan
