Input: Read this: In a book called Science Versus Crime, Houck writes that Popper's falsificationism can be questioned logically: it is not clear how Popper would deal with a statement like "for every metal, there is a temperature at which it will melt." The hypothesis cannot be falsified by any possible observation, for there will always be a higher temperature than tested at which the metal may in fact melt, yet it seems to be a valid scientific hypothesis. These examples were pointed out by Carl Gustav Hempel. Hempel came to acknowledge that Logical Positivism's verificationism was untenable, but argued that falsificationism was equally untenable on logical grounds alone. The simplest response to this is that, because Popper describes how theories attain, maintain and lose scientific status, individual consequences of currently accepted scientific theories are scientific in the sense of being part of tentative scientific knowledge, and both of Hempel's examples fall under this category. For instance, atomic theory implies that all metals melt at some temperature.
Question: What implies that not all metals melt?

Output: unanswerable


Input: Read this: But early in the 16th century, a brilliant new red appeared in Europe. When the Spanish conquistador Hernán Cortés and his soldiers conquered the Aztec Empire in 1519-1521, they discovered slowly that the Aztecs had another treasure beside silver and gold; they had the tiny cochineal, a parasitic scale insect which lived on cactus plants, which, when dried and crushed, made a magnificent red. The cochineal in Mexico was closely related to the Kermes varieties of Europe, but unlike European Kermes, it could be harvested several times a year, and it was ten times stronger than the Kermes of Poland. It worked particularly well on silk, satin and other luxury textiles. In 1523 Cortes sent the first shipment to Spain. Soon cochineal began to arrive in European ports aboard convoys of Spanish galleons.
Question: What happened in 1519?

Output: unanswerable


Input: Read this: According to the writer of Luke, Mary was a relative of Elizabeth, wife of the priest Zechariah of the priestly division of Abijah, who was herself part of the lineage of Aaron and so of the tribe of Levi.[Luke 1:5;1:36] Some of those who consider that the relationship with Elizabeth was on the maternal side, consider that Mary, like Joseph, to whom she was betrothed, was of the House of David and so of the Tribe of Judah, and that the genealogy of Jesus presented in Luke 3 from Nathan, third son of David and Bathsheba, is in fact the genealogy of Mary,[need quotation to verify] while the genealogy from Solomon given in Matthew 1 is that of Joseph. (Aaron's wife Elisheba was of the tribe of Judah, so all their descendants are from both Levi and Judah.)[Num.1:7 & Ex.6:23]
Question: What tribe did Luke belong to?

Output:
unanswerable
