Input: Read this: By the 1st century, Babylonia, to which Jews migrated to after the Babylonian conquest as well as after the Bar Kokhba revolt in 135 CE, already held a speedily growing population of an estimated 1,000,000 Jews, which increased to an estimated 2 million between the years 200 CE 500 CE, both by natural growth and by immigration of more Jews from the Land of Israel, making up about 1/6 of the world Jewish population at that era. At times conversion has accounted for a part of Jewish population growth. Some have claimed that in the 1st century of the Christian era, for example, the population more than doubled, from four to 810 million within the confines of the Roman Empire, in good part as a result of a wave of conversion.
Question: Between what years did Jews increase to an estimated 2 million?

Output: 200 CE 500 CE

QUES: Meanwhile, U.S. garrisons in Japan continually dispatched soldiers and materiel to reinforce defenders in the Pusan Perimeter. Tank battalions deployed to Korea directly from the U.S. mainland from the port of San Francisco to the port of Pusan, the largest Korean port. By late August, the Pusan Perimeter had some 500 medium tanks battle-ready. In early September 1950, ROK Army and UN Command forces outnumbered the KPA 180,000 to 100,000 soldiers. The UN forces, once prepared, counterattacked and broke out of the Pusan Perimeter.

Seeking national reconciliation between revolutionaries and Catholics, the Concordat of 1801 was signed on 15 July 1801 between Napoleon and Pope Pius VII. It solidified the Roman Catholic Church as the majority church of France and brought back most of its civil status. The hostility of devout Catholics against the state had now largely been resolved. It did not restore the vast church lands and endowments that had been seized during the revolution and sold off. As a part of the Concordat, he presented another set of laws called the Organic Articles.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The Concordat of 1801 strengthened the position of which church as the majority church of France?
Ah, so.. the Roman Catholic Church

Question: The etymology of the name Bern is uncertain. According to the local legend, based on folk etymology, Berchtold V, Duke of Zahringen, the founder of the city of Bern, vowed to name the city after the first animal he met on the hunt, and this turned out to be a bear. It has long been considered likely that the city was named after the Italian city of Verona, which at the time was known as Bern in Middle High German. As a result of the find of the Bern zinc tablet in the 1980s, it is now more common to assume that the city was named after a pre-existing toponym of Celtic origin, possibly *berna "cleft". The bear was the heraldic animal of the seal and coat of arms of Bern from at least the 1220s. The earliest reference to the keeping of live bears in the Barengraben dates to the 1440s.
Try to answer this question if possible: What animal is on the seal and coat of arms of Bern?
Answer: bear

Input: Read this: Heartwood is often visually distinct from the living sapwood, and can be distinguished in a cross-section where the boundary will tend to follow the growth rings. For example, it is sometimes much darker. However, other processes such as decay or insect invasion can also discolor wood, even in woody plants that do not form heartwood, which may lead to confusion.
Question: What kind of plants never form heartwood?

Output:
woody
