Input: Read this: An electrostatic motor is based on the attraction and repulsion of electric charge. Usually, electrostatic motors are the dual of conventional coil-based motors. They typically require a high-voltage power supply, although very small motors employ lower voltages. Conventional electric motors instead employ magnetic attraction and repulsion, and require high current at low voltages. In the 1750s, the first electrostatic motors were developed by Benjamin Franklin and Andrew Gordon. Today the electrostatic motor finds frequent use in micro-electro-mechanical systems (MEMS) where their drive voltages are below 100 volts, and where moving, charged plates are far easier to fabricate than coils and iron cores. Also, the molecular machinery which runs living cells is often based on linear and rotary electrostatic motors.[citation needed]
Question: What two inventors developed the first electrostatic motors?

Output: Benjamin Franklin and Andrew Gordon


QUES: In June, Truman became the first president to address the NAACP. His speech was a significant departure from traditional race relations in the United States. In front of 10,000 people at the Lincoln Memorial, the president left no doubt where he stood on civil rights. According to his speech, America had "reached a turning point in the long history of our country's efforts to guarantee freedom and equality to all our citizens…Each man must be guaranteed equality of opportunity." He proposed what black citizens had been calling for - an enhanced role of federal authority through the states. "We must make the Federal government a friendly, vigilant defender of the rights and equalities of all Americans. And again I mean all Americans.":40

QUES: The Japanese defenders recognized the possibility of a renewed invasion, and began construction of a great stone barrier around Hakata Bay in 1276. Completed in 1277, this wall stretched for 20 kilometers around the border of the bay. This would later serve as a strong defensive point against the Mongols. The Mongols attempted to settle matters in a diplomatic way from 1275 to 1279, but every envoy sent to Japan was executed. This set the stage for one of the most famous engagements in Japanese history.
When did Japan begin building the Hakata Bay barrier?

ANS: 1276


In the year 712, Muhammad bin Qasim, an Umayyad general, sailed from the Persian Gulf into Sindh in Pakistan and conquered both the Sindh and the Punjab regions along the Indus river. The conquest of Sindh and Punjab, in modern-day Pakistan, although costly, were major gains for the Umayyad Caliphate. However, further gains were halted by Hindu kingdoms in India in the battle of Rajasthan. The Arabs tried to invade India but they were defeated by the north Indian king Nagabhata of the Pratihara Dynasty and by the south Indian Emperor Vikramaditya II of the Chalukya dynasty in the early 8th century. After this the Arab chroniclers admit that the Caliph Mahdi "gave up the project of conquering any part of India."
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What conquests were easy for Umayyad Caliphate?
Ah, so.. unanswerable


Question: National Basketball Association teams play eight preseason games per year. Today, NBA teams almost always play each other in the preseason, but mainly at neutral sites within their market areas in order to allow those who can't usually make a trip to a home team's arena during the regular season to see a game close to home; for instance the Minnesota Timberwolves will play games in arenas in North Dakota and South Dakota, while the Phoenix Suns schedule one exhibition game outdoors at Indian Wells Tennis Garden in Indian Wells, California yearly, the only such instance an NBA game takes place in an outdoor venue.
Try to answer this question if possible: What venue do the Suns play at in Indian Wells?
Answer: Indian Wells Tennis Garden


Input: Read this: Tyson Research Center is a 2,000-acre (809 ha) field station located west of St. Louis on the Meramec River. Washington University obtained Tyson as surplus property from the federal government in 1963. It is used by the University as a biological field station and research/education center. In 2010 the Living Learning Center was named one of the first two buildings accredited nationwide as a "living building" under the Living Building Challenge, opened to serve as a biological research station and classroom for summer students.
Question: When did Washington University acquire the property for Tyson Research Center?

Output:
1963
