The problem: Answer a question about this article:
As regards knowledge of languages, Tito replied that he spoke Serbo-Croatian, German, Russian, and some English. A biographer also stated that he spoke "Serbo-Croatian ... Russian, Czech, Slovenian ... German (with a Viennese accent) ... understands and reads French and Italian ... [and] also speaks Kirghiz."
Other than Serbo-Croatian, German, Russian, Czech, Slovenian and English, French and Italian, what language does Tito speak?
****
The answer: Kirghiz


Problem: Please answer a question about the following article about Asphalt:
Because of the difficulty of moving crude bitumen through pipelines, non-upgraded bitumen is usually diluted with natural-gas condensate in a form called dilbit or with synthetic crude oil, called synbit. However, to meet international competition, much non-upgraded bitumen is now sold as a blend of multiple grades of bitumen, conventional crude oil, synthetic crude oil, and condensate in a standardized benchmark product such as Western Canadian Select. This sour, heavy crude oil blend is designed to have uniform refining characteristics to compete with internationally marketed heavy oils such as Mexican Mayan or Arabian Dubai Crude.
What is the natural gas condensate used to dilute bitumen?
A: dilbit

The lowest pressure that can be attained in a system is also dependent on many things other than the nature of the pumps. Multiple pumps may be connected in series, called stages, to achieve higher vacuums. The choice of seals, chamber geometry, materials, and pump-down procedures will all have an impact. Collectively, these are called vacuum technique. And sometimes, the final pressure is not the only relevant characteristic. Pumping systems differ in oil contamination, vibration, preferential pumping of certain gases, pump-down speeds, intermittent duty cycle, reliability, or tolerance to high leakage rates.

What are two other relevant characteristics of a pumping system along with final pressure?
Answer: oil contamination, vibration


Problem: The first half of the 14th century saw much important scientific work being done, largely within the framework of scholastic commentaries on Aristotle's scientific writings. William of Ockham introduced the principle of parsimony: natural philosophers should not postulate unnecessary entities, so that motion is not a distinct thing but is only the moving object and an intermediary "sensible species" is not needed to transmit an image of an object to the eye. Scholars such as Jean Buridan and Nicole Oresme started to reinterpret elements of Aristotle's mechanics. In particular, Buridan developed the theory that impetus was the cause of the motion of projectiles, which was a first step towards the modern concept of inertia. The Oxford Calculators began to mathematically analyze the kinematics of motion, making this analysis without considering the causes of motion.
What did the Oxford Calculators measure?
The answer is the following: the kinematics of motion


A similar fate befell the Curonians who lived in the area around the Curonian Lagoon. While many fled from the Red Army during the evacuation of East Prussia, Curonians that remained behind were subsequently expelled by the Soviet Union. Only 219 lived along the Curonian Spit in 1955. Many had German names such as Fritz or Hans, a cause for anti-German discrimination. The Soviet authorities considered the Curonians fascists. Because of this discrimination, many immigrated to West Germany in 1958, where the majority of Curonians now live.
Where did most of the Curonians flee to in 1958?
West Germany


Here is a question about this article: 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.
What is the answer to this question: Generally, what powered the relay contoller?
****
So...
MG set
