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 second electrostatic motors?

QUES: Baptist missionary work in Canada began in the British colony of Nova Scotia (present day Nova Scotia and New Brunswick) in the 1760s. The first official record of a Baptist church in Canada was that of the Horton Baptist Church (now Wolfville) in Wolfville, Nova Scotia on 29 October 1778. The church was established with the assistance of the New Light evangelist Henry Alline. Many of Alline's followers, after his death, would convert and strengthen the Baptist presence in the Atlantic region.[page needed] Two major groups of Baptists formed the basis of the churches in the Maritimes. These were referred to as Regular Baptist (Calvinistic in their doctrine) and Free Will Baptists.

When did missionary work begin in Canada?
What is the answer?
ANS: 1760s

QUES: Addition of lead(II) oxide lowers melting point, lowers viscosity of the melt, and increases refractive index. Lead oxide also facilitates solubility of other metal oxides and is used in colored glasses. The viscosity decrease of lead glass melt is very significant (roughly 100 times in comparison with soda glasses); this allows easier removal of bubbles and working at lower temperatures, hence its frequent use as an additive in vitreous enamels and glass solders. The high ionic radius of the Pb2+ ion renders it highly immobile in the matrix and hinders the movement of other ions; lead glasses therefore have high electrical resistance, about two orders of magnitude higher than soda-lime glass (108.5 vs 106.5 Ohmcm, DC at 250 C). For more details, see lead glass.
Lead oxide makes it easier to dissolve what?

ANS: other metal oxides

Although STOVL aircraft are capable of taking off vertically from a spot on the deck, using the ramp and a running start is far more fuel efficient and permits a heavier launch weight. As catapults are unnecessary, carriers with this arrangement reduce weight, complexity, and space needed for complex steam or electromagnetic launching equipment, vertical landing aircraft also remove the need for arresting cables and related hardware. Russian, Chinese, and future Indian carriers include a ski-jump ramp for launching lightly loaded conventional fighter aircraft but recover using traditional carrier arresting cables and a tailhook on their aircraft.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What landing aircraft have removed the need for arresting cables?
Ah, so.. vertical

Question: Gothic architecture is a style of architecture that flourished during the high and late medieval period. It evolved from Romanesque architecture and was succeeded by Renaissance architecture. Originating in 12th-century France and lasting into the 16th century, Gothic architecture was known during the period as Opus Francigenum ("French work") with the term Gothic first appearing during the later part of the Renaissance. Its characteristics include the pointed arch, the ribbed vault and the flying buttress. Gothic architecture is most familiar as the architecture of many of the great cathedrals, abbeys and churches of Europe. It is also the architecture of many castles, palaces, town halls, guild halls, universities and to a less prominent extent, private dwellings, such as dorms and rooms.
Try to answer this question if possible: What style of architecture no longer exists for castles?
Answer: unanswerable

Context and question: A few days before the fall of the city, the National Government of China was relocated to the southwestern city Chungking (Chongqing) and resumed Chinese resistance. In 1940, a Japanese-collaborationist government known as the "Nanjing Regime" or "Reorganized National Government of China" led by Wang Jingwei was established in Nanjing as a rival to Chiang Kai-shek's government in Chongqing. In 1946, after the Surrender of Japan, the KMT relocated its central government back to Nanjing.
When did the KMT move back to Nanjing?
Answer:
1946
