Problem: The dogs' value to early human hunter-gatherers led to them quickly becoming ubiquitous across world cultures. Dogs perform many roles for people, such as hunting, herding, pulling loads, protection, assisting police and military, companionship, and, more recently, aiding handicapped individuals. This impact on human society has given them the nickname "man's best friend" in the Western world. In some cultures, however, dogs are also a source of meat.
Dogs have hunted with and done other things for people for a long time, but what is a more recent help to people they provide?
The answer is the following: aiding handicapped individuals.

Problem: In Western Europe, some of the older Roman elite families died out while others became more involved with Church than secular affairs. Values attached to Latin scholarship and education mostly disappeared, and while literacy remained important, it became a practical skill rather than a sign of elite status. In the 4th century, Jerome (d. 420) dreamed that God rebuked him for spending more time reading Cicero than the Bible. By the 6th century, Gregory of Tours (d. 594) had a similar dream, but instead of being chastised for reading Cicero, he was chastised for learning shorthand. By the late 6th century, the principal means of religious instruction in the Church had become music and art rather than the book. Most intellectual efforts went towards imitating classical scholarship, but some original works were created, along with now-lost oral compositions. The writings of Sidonius Apollinaris (d. 489), Cassiodorus (d. c. 585), and Boethius (d. c. 525) were typical of the age.
In what year did Jerome die?
The answer is the following: 420

Problem: In agriculture, the increased usage of sheep with long-fibred wool allowed a stronger thread to be spun. In addition, the spinning wheel replaced the traditional distaff for spinning wool, tripling production.[AI] A less technological refinement that still greatly affected daily life was the use of buttons as closures for garments, which allowed for better fitting without having to lace clothing on the wearer. Windmills were refined with the creation of the tower mill, allowing the upper part of the windmill to be spun around to face the direction from which the wind was blowing. The blast furnace appeared around 1350 in Sweden, increasing the quantity of iron produced and improving its quality. The first patent law in 1447 in Venice protected the rights of inventors to their inventions.
In what country did the blast furnace first appear?
The answer is the following: Sweden

Problem: After the war, Feynman declined an offer from the Institute for Advanced Study in Princeton, New Jersey, despite the presence there of such distinguished faculty members as Albert Einstein, Kurt Gödel and John von Neumann. Feynman followed Hans Bethe, instead, to Cornell University, where Feynman taught theoretical physics from 1945 to 1950. During a temporary depression following the destruction of Hiroshima by the bomb produced by the Manhattan Project, he focused on complex physics problems, not for utility, but for self-satisfaction. One of these was analyzing the physics of a twirling, nutating dish as it is moving through the air. His work during this period, which used equations of rotation to express various spinning speeds, proved important to his Nobel Prize–winning work, yet because he felt burned out and had turned his attention to less immediately practical problems, he was surprised by the offers of professorships from other renowned universities.
Which colleague did Feynman follow to Cornell?
The answer is the following:
Hans Bethe
