Question: Passage: Despite yet another offer from the Institute for Advanced Study, Feynman rejected the Institute on the grounds that there were no teaching duties: Feynman felt that students were a source of inspiration and teaching was a diversion during uncreative spells. Because of this, the Institute for Advanced Study and Princeton University jointly offered him a package whereby he could teach at the university and also be at the institute.[citation needed] Feynman instead accepted an offer from the California Institute of Technology (Caltech)—and as he says in his book Surely You're Joking Mr. Feynman!—because a desire to live in a mild climate had firmly fixed itself in his mind while he was installing tire chains on his car in the middle of a snowstorm in Ithaca.

Answer: Why did Feynman decide to accept all offers from the Institute of Advanced Study?


Question: Passage: Literature allows readers to access intimate emotional aspects of a person’s character that would not be obvious otherwise. It benefits the psychological development and understanding of the reader. For example, it allows a person to access emotional states from which the person has distanced himself or herself. An entry written by D. Mitchell featured in ‘‘The English Journal’’ explains how the author utilized young adult literature in order to re-experience the emotional psychology she experienced as a child which she describes as a state of “wonder”.

Answer: What gives readers access to physical aspects of a character?


Question: Passage: In the medieval Islamic world, an elementary school was known as a maktab, which dates back to at least the 10th century. Like madaris (which referred to higher education), a maktab was often attached to an endowed mosque. In the 11th century, the famous Persian Islamic philosopher and teacher Ibn Sīnā (known as Avicenna in the West), in one of his books, wrote a chapter about the maktab entitled "The Role of the Teacher in the Training and Upbringing of Children," as a guide to teachers working at maktab schools. He wrote that children can learn better if taught in classes instead of individual tuition from private tutors, and he gave a number of reasons for why this is the case, citing the value of competition and emulation among pupils, as well as the usefulness of group discussions and debates. Ibn Sīnā described the curriculum of a maktab school in some detail, describing the curricula for two stages of education in a maktab school.

Answer:
 When were the last recorded Islamic elementary schools?
