Problem: Jews:

Although the Israelites were divided into Twelve Tribes, the Jews (being one offshoot of the Israelites, another being the Samaritans) are traditionally said to descend mostly from the Israelite tribes of Judah (from where the Jews derive their ethnonym) and Benjamin, and partially from the tribe of Levi, who had together formed the ancient Kingdom of Judah, and the remnants of the northern Kingdom of Israel who migrated to the Kingdom of Judah and assimilated after the 720s BCE, when the Kingdom of Israel was conquered by the Neo-Assyrian Empire.

From where do the Jews derive their ethonynm?

A: Israelite tribes of Judah


Problem: Thuringia became a landgraviate in 1130 AD. After the extinction of the reigning Ludowingian line of counts and landgraves in 1247 and the War of the Thuringian Succession (1247–1264), the western half became independent under the name of "Hesse", never to become a part of Thuringia again. Most of the remaining Thuringia came under the rule of the Wettin dynasty of the nearby Margraviate of Meissen, the nucleus of the later Electorate and Kingdom of Saxony. With the division of the house of Wettin in 1485, Thuringia went to the senior Ernestine branch of the family, which subsequently subdivided the area into a number of smaller states, according to the Saxon tradition of dividing inheritance amongst male heirs. These were the "Saxon duchies", consisting, among others, of the states of Saxe-Weimar, Saxe-Eisenach, Saxe-Jena, Saxe-Meiningen, Saxe-Altenburg, Saxe-Coburg, and Saxe-Gotha; Thuringia became merely a geographical concept.
When did Thuringia become a landgraviate?

Answer: in 1130 AD

On the difference between the ideals of architecture and mere construction, the renowned 20th-century architect Le Corbusier wrote: "You employ stone, wood, and concrete, and with these materials you build houses and palaces: that is construction. Ingenuity is at work. But suddenly you touch my heart, you do me good. I am happy and I say: This is beautiful. That is Architecture".
What job did Le Corbusier quit?
A: unanswerable


Context and question: Once inside the Rotunda for the Charters of Freedom, there are no lines to see the individual documents and visitors are allowed to walk from document to document as they wish. For over 30 years the National Archives have forbidden flash photography but the advent of cameras with automatic flashes have made the rules increasingly difficult to enforce. As a result, all filming, photographing, and videotaping by the public in the exhibition areas has been prohibited since February 25, 2010.
What year did the National Archives open to the public?
Answer: unanswerable


Question: Other notable new vaccines of the period include those for measles (1962, John Franklin Enders of Children's Medical Center Boston, later refined by Maurice Hilleman at Merck), Rubella (1969, Hilleman, Merck) and mumps (1967, Hilleman, Merck) The United States incidences of rubella, congenital rubella syndrome, measles, and mumps all fell by >95% in the immediate aftermath of widespread vaccination. The first 20 years of licensed measles vaccination in the U.S. prevented an estimated 52 million cases of the disease, 17,400 cases of mental retardation, and 5,200 deaths.
Is there an answer to this question: What did the first measles prevent in it's first 20 years?

Answer: an estimated 52 million cases of the disease, 17,400 cases of mental retardation, and 5,200 deaths

Neptune is not visible to the unaided eye and is the only planet in the Solar System found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed with a telescope on 23 September 1846 by Johann Galle within a degree of the position predicted by Urbain Le Verrier. Its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining known 14 moons were located telescopically until the 20th century. The planet's distance from Earth gives it a very small apparent size, making it challenging to study with Earth-based telescopes. Neptune was visited by Voyager 2, when it flew by the planet on 25 August 1989. The advent of Hubble Space Telescope and large ground-based telescopes with adaptive optics has recently allowed for additional detailed observations from afar.
Who observed neptune with a telescope in the 18th century?
A:
unanswerable
