input question: Extract the answer to the question from the following context. Question: what are the last machines mentioned? Context: Apple spent $2.5 million purchasing all 39 advertising pages in a special, post-election issue of Newsweek, and ran a "Test Drive a Macintosh" promotion, in which potential buyers with a credit card could take home a Macintosh for 24 hours and return it to a dealer afterwards. While 200,000 people participated, dealers disliked the promotion, the supply of computers was insufficient for demand, and many were returned in such a bad condition that they could no longer be sold. This marketing campaign caused CEO John Sculley to raise the price from US$1,995 to US$2,495 (about $5,200 when adjusted for inflation in 2010). The computer sold well, nonetheless, reportedly outselling the IBM PCjr which also began shipping early that year. By April 1984 the company sold 50,000 Macintoshes, and hoped for 70,000 by early May and almost 250,000 by the end of the year.???
output answer: Macintoshes
Extract the answer to the question from the following context. Question: What facilitated Semitic influence? Context: Later, the 3rd dynasty of Ur under Ur-Nammu and Shulgi, whose power extended as far as southern Assyria, was the last great "Sumerian renaissance", but already the region was becoming more Semitic than Sumerian, with the rise in power of the Akkadian speaking Semites in Assyria and elsewhere, and the influx of waves of Semitic Martu (Amorites) who were to found several competing local powers including Isin, Larsa, Eshnunna and eventually Babylon. The last of these eventually came to dominate the south of Mesopotamia as the Babylonian Empire, just as the Old Assyrian Empire had already done so in the north from the late 21st century BC. The Sumerian language continued as a sacerdotal language taught in schools in Babylonia and Assyria, much as Latin was used in the Medieval period, for as long as cuneiform was utilized.

Answer: the rise in power of the Akkadian speaking Semites in Assyria and elsewhere, and the influx of waves of Semitic Martu (Amorites)
Q: Extract the answer to the question from the following context. Question: What statement supports that blacks were born free and allowed to marry? Context: The first settlers primarily came from England, its Caribbean colony of Barbados, and its Atlantic colony of Bermuda. Among these were free people of color, born in the West Indies of alliances and marriages between Africans and Englanders, when color lines were looser among the working class in the early colonial years, and some wealthy whites took black consorts or concubines. Charles Town attracted a mixture of ethnic and religious groups. French, Scottish, Irish, and Germans migrated to the developing seacoast town, representing numerous Protestant denominations. Because of the battles between English "royalty" and the Roman Catholic Church, practicing Catholics were not allowed to settle in South Carolina until after the American Revolution. Jews were allowed, and Sephardic Jews migrated to the city in such numbers that by the beginning of the 19th century, the city was home to the largest and wealthiest Jewish community in North Americaa status it held until about 1830.
A: Among these were free people of color, born in the West Indies of alliances and marriages between Africans and Englanders
Question: Extract the answer to the question from the following context. Question: What event gave the population of Beringia the chance to travel? Context: Indigenous genetic studies suggest that the first inhabitants of the Americas share a single ancestral population, one that developed in isolation, conjectured to be Beringia. The isolation of these peoples in Beringia might have lasted 1020,000 years. Around 16,500 years ago, the glaciers began melting, allowing people to move south and east into Canada and beyond. These people are believed to have followed herds of now-extinct Pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran Ice Sheets.
Answer: the glaciers began melting
[Q]: Extract the answer to the question from the following context. Question: Which architect represented a smaller region? Context: From the middle of the 18th century, exploration and publication changed the course of British architecture towards a purer vision of the Ancient Greco-Roman ideal. James 'Athenian' Stuart's work The Antiquities of Athens and Other Monuments of Greece was very influential in this regard, as were Robert Wood's Palmyra and Baalbec. A combination of simple forms and high levels of enrichment was adopted by the majority of contemporary British architects and designers. The revolution begun by Stuart was soon to be eclipsed by the work of the Adam Brothers, James Wyatt, Sir William Chambers, George Dance, James Gandon and provincially based architects such as John Carr and Thomas Harrison of Chester.

Problem: Given the question: Extract the answer to the question from the following context. Question: Where are AC motors not used? Context: 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.

The answer is:
larger capacity elevators
