Input: Read this: The first practical ICs were invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor. Kilby recorded his initial ideas concerning the integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as "a body of semiconductor material ... wherein all the components of the electronic circuit are completely integrated". Noyce also came up with his own idea of an integrated circuit half a year later than Kilby. His chip solved many practical problems that Kilby's had not. Produced at Fairchild Semiconductor, it was made of silicon, whereas Kilby's chip was made of germanium.
Question: Noyce's IC was made up of what material?

Output: silicon

Input: Read this: After the Civil War, racial segregation forced African Americans to share more of a common lot in society than they might have given widely varying ancestry, educational and economic levels. The binary division altered the separate status of the traditionally free people of color in Louisiana, for instance, although they maintained a strong Louisiana Creole culture related to French culture and language, and practice of Catholicism. African Americans began to create common causeregardless of their multiracial admixture or social and economic stratification. In 20th-century changes, during the rise of the Civil Rights and Black Power movements, the African-American community increased its own pressure for people of any portion of African descent to be claimed by the black community to add to its power.
Question: As an example, whose status was downgraded after the civil war?

Output: traditionally free people of color in Louisiana

Input: Read this: When John's elder brother Richard became king in September 1189, he had already declared his intention of joining the Third Crusade. Richard set about raising the huge sums of money required for this expedition through the sale of lands, titles and appointments, and attempted to ensure that he would not face a revolt while away from his empire. John was made Count of Mortain, was married to the wealthy Isabel of Gloucester, and was given valuable lands in Lancaster and the counties of Cornwall, Derby, Devon, Dorset, Nottingham and Somerset, all with the aim of buying his loyalty to Richard whilst the king was on crusade. Richard retained royal control of key castles in these counties, thereby preventing John from accumulating too much military and political power, and, for the time being, the king named the four-year-old Arthur of Brittany as the heir to the throne. In return, John promised not to visit England for the next three years, thereby in theory giving Richard adequate time to conduct a successful crusade and return from the Levant without fear of John seizing power. Richard left political authority in England the post of justiciar jointly in the hands of Bishop Hugh de Puiset and William Mandeville, and made William Longchamp, the Bishop of Ely, his chancellor. Mandeville immediately died, and Longchamp took over as joint justiciar with Puiset, which would prove to be a less than satisfactory partnership. Eleanor, the queen mother, convinced Richard to allow John into England in his absence.
Question: Who convinced Richard to allow John to join into England?

Output: Eleanor

Input: Read this: The shelter of the early people changed dramatically from the paleolithic to the neolithic era. In the paleolithic, people did not normally live in permanent constructions. In the neolithic, mud brick houses started appearing that were coated with plaster. The growth of agriculture made permanent houses possible. Doorways were made on the roof, with ladders positioned both on the inside and outside of the houses. The roof was supported by beams from the inside. The rough ground was covered by platforms, mats, and skins on which residents slept. Stilt-houses settlements were common in the Alpine and Pianura Padana (Terramare) region. Remains have been found at the Ljubljana Marshes in Slovenia and at the Mondsee and Attersee lakes in Upper Austria, for example.
Question: What era consisted of people living on roofs?

Output:
unanswerable
