Input: Article: Around 13001350 the Medieval Warm Period gave way to the Little Ice Age. The colder climate resulted in agricultural crises, the first of which is known as the Great Famine of 1315-1317. The demographic consequences of this famine, however, were not as severe as the plagues that occurred later in the century, particularly the Black Death. Estimates of the death rate caused by this epidemic range from one third to as much as sixty percent. By around 1420, the accumulated effect of recurring plagues and famines had reduced the population of Europe to perhaps no more than a third of what it was a century earlier. The effects of natural disasters were exacerbated by armed conflicts; this was particularly the case in France during the Hundred Years' War.

Now answer this question: What was the effect of the Little Ice Age?

Output: agricultural crises

Article: In 1986, Michael Dell brought in Lee Walker, a 51-year-old venture capitalist, as president and chief operating officer, to serve as Michael's mentor and implement Michael's ideas for growing the company. Walker was also instrumental in recruiting members to the board of directors when the company went public in 1988. Walker retired in 1990 due to health, and Michael Dell hired Morton Meyerson, former CEO and president of Electronic Data Systems to transform the company from a fast-growing medium-sized firm into a billion-dollar enterprise.

Question: What did Lee Walker recruit members to Dell for?
Ans: board of directors

Here is a question about this article: Historically, AC motors were used for single or double speed elevator machines on the grounds of cost and lower usage applications where car speed and passenger comfort were less of an issue, but for higher speed, larger capacity elevators, the need for infinitely variable speed control over the traction machine becomes an issue. Therefore, DC machines powered by an AC/DC motor generator were the preferred solution. The MG set also typically powered the relay controller of the elevator, which has the added advantage of electrically isolating the elevators from the rest of a building's electrical system, thus eliminating the transient power spikes in the building's electrical supply caused by the motors starting and stopping (causing lighting to dim every time the elevators are used for example), as well as interference to other electrical equipment caused by the arcing of the relay contactors in the control system.
What is the answer to this question: Throughout history, what type of engines were used for elevator machines?
****
So... AC motors

Problem: Please answer a question about the following article about Freemasonry:
At the dawn of the Grand Lodge era, during the 1720s, James Anderson composed the first printed constitutions for Freemasons, the basis for most subsequent constitutions, which specifically excluded women from Freemasonry. As Freemasonry spread, continental masons began to include their ladies in Lodges of Adoption, which worked three degrees with the same names as the men's but different content. The French officially abandoned the experiment in the early 19th century. Later organisations with a similar aim emerged in the United States, but distinguished the names of the degrees from those of male masonry.
When was the dawn of the Grand Lodge era?
A: during the 1720s

Question: Read this and answer the question

The period saw several important technical innovations, like the principle of linear perspective found in the work of Masaccio, and later described by Brunelleschi. Greater realism was also achieved through the scientific study of anatomy, championed by artists like Donatello. This can be seen particularly well in his sculptures, inspired by the study of classical models. As the centre of the movement shifted to Rome, the period culminated in the High Renaissance masters da Vinci, Michelangelo and Raphael.

Along with da Vinci, who were two other artists regarded as masters of the High Renaissance?
Answer:
Michelangelo and Raphael
