Extract the answer to the question from the following context. Question: What is it equal to? Context: The Faraday constant F is the charge of one mole of electrons, equal to the Avogadro constant NA multiplied by the elementary charge e. It can be determined by careful electrolysis experiments, measuring the amount of silver dissolved from an electrode in a given time and for a given electric current. In practice, it is measured in conventional electrical units, and so given the symbol F90. Substituting the definitions of NA and e, and converting from conventional electrical units to SI units, gives the relation to the Planck constant.
Ans: Substituting the definitions of NA and e, and converting from conventional electrical units to SI units, gives the relation to the Planck constant

Extract the answer to the question from the following context. Question: How did some women defy tradition? Context: As the Tokugawa period progressed more value became placed on education, and the education of females beginning at a young age became important to families and society as a whole. Marriage criteria began to weigh intelligence and education as desirable attributes in a wife, right along with physical attractiveness. Though many of the texts written for women during the Tokugawa period only pertained to how a woman could become a successful wife and household manager, there were those that undertook the challenge of learning to read, and also tackled philosophical and literary classics. Nearly all women of the samurai class were literate by the end of the Tokugawa period.
Ans: undertook the challenge of learning to read, and also tackled philosophical and literary classics

Extract the answer to the question from the following context. Question: What was the possible temperature of the atmosphere? Context: The climate of the Cretaceous is less certain and more widely disputed. Higher levels of carbon dioxide in the atmosphere are thought to have caused the world temperature gradient from north to south to become almost flat: temperatures were about the same across the planet. Average temperatures were also higher than today by about 10C. In fact, by the middle Cretaceous, equatorial ocean waters (perhaps as warm as 20 C in the deep ocean) may have been too warm for sea life,[dubious discuss][citation needed] and land areas near the equator may have been deserts despite their proximity to water. The circulation of oxygen to the deep ocean may also have been disrupted.[dubious discuss] For this reason, large volumes of organic matter that was unable to decompose accumulated, eventually being deposited as "black shale".
Ans: 10C

Extract the answer to the question from the following context. Question: where does OKCFD operates? Context: Oklahoma City is protected by the Oklahoma City Fire Department (OKCFD), which employs 1015 paid, professional firefighters. The current Chief of Department is G. Keith Bryant, the department is also commanded by three Deputy Chiefs, who along with the department chief oversee the Operational Services, Prevention Services, and Support Services bureaus. The OKCFD currently operates out of 37 fire stations, located throughout the city in six battalions. The OKCFD also operates a fire apparatus fleet of 36 engines (including 30 paramedic engines), 13 ladders, 16 brush patrol units, six water tankers, two hazardous materials units, one Technical Rescue Unit, one Air Supply Unit, six Arson Investigation Units, and one Rehabilitation Unit. Each engine is staffed with a driver, an officer, and one to two firefighters, while each ladder company is staffed with a driver, an officer, and one firefighter. Minimum staffing per shift is 213 personnel. The Oklahoma City Fire Department responds to over 70,000 emergency calls annually.
Ans: Oklahoma City
