Problem: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "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."?

A: What could potentially affect motor that were close but not part of the elevator should the system not be isolated?

input question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "The Romans are known for the great number of deities they honored, a capacity that earned the mockery of early Christian polemicists. The presence of Greeks on the Italian peninsula from the beginning of the historical period influenced Roman culture, introducing some religious practices that became as fundamental as the cult of Apollo. The Romans looked for common ground between their major gods and those of the Greeks (interpretatio graeca), adapting Greek myths and iconography for Latin literature and Roman art. Etruscan religion was also a major influence, particularly on the practice of augury."????
output answer: Who were the gods of the Greeks?
I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "During the Second Punic War in 218 BC, the Carthaginian general Hannibal probably crossed the Alps with an army numbering 38,000 infantry, 8,000 cavalry, and 37 war elephants. This was one of the most celebrated achievements of any military force in ancient warfare, although no evidence exists of the actual crossing or the place of crossing. The Romans, however, had built roads along the mountain passes, which continued to be used through the medieval period to cross the mountains and Roman road markers can still be found on the mountain passes."?
----
Answer: Did Hannibal have more infantry or war elephants in his army?
Q: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Switzerland was the last Western republic to grant women the right to vote. Some Swiss cantons approved this in 1959, while at the federal level it was achieved in 1971 and, after resistance, in the last canton Appenzell Innerrhoden (one of only two remaining Landsgemeinde) in 1990. After obtaining suffrage at the federal level, women quickly rose in political significance, with the first woman on the seven member Federal Council executive being Elisabeth Kopp, who served from 19841989, and the first female president being Ruth Dreifuss in 1999."?
A: What, with regards to women's right to vote in Switzerland, happened in the 60th year of the century known as the 1900s?
[Q]: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Hoover began using wiretapping in the 1920s during Prohibition to arrest bootleggers. In the 1927 case Olmstead v. United States, in which a bootlegger was caught through telephone tapping, the United States Supreme Court ruled that FBI wiretaps did not violate the Fourth Amendment as unlawful search and seizure, as long as the FBI did not break into a person's home to complete the tapping. After Prohibition's repeal, Congress passed the Communications Act of 1934, which outlawed non-consensual phone tapping, but allowed bugging. In the 1939 case Nardone v. United States, the court ruled that due to the 1934 law, evidence the FBI obtained by phone tapping was inadmissible in court. After the 1967 case Katz v. United States overturned the 1927 case that had allowed bugging, Congress passed the Omnibus Crime Control Act, allowing public authorities to tap telephones during investigations as long as they obtain a warrant beforehand."?
