Input: Read this: Expansive interior light has been a feature of Gothic cathedrals since the first structure was opened. The metaphysics of light in the Middle Ages led to clerical belief in its divinity and the importance of its display in holy settings. Much of this belief was based on the writings of Pseudo-Dionysius, a sixth-century mystic whose book, The Celestial Hierarchy, was popular among monks in France. Pseudo-Dionysius held that all light, even light reflected from metals or streamed through windows, was divine. To promote such faith, the abbot in charge of the Saint-Denis church on the north edge of Paris, the Abbot Suger, encouraged architects remodeling the building to make the interior as bright as possible.
Question: Whose writings led to the clerical belief in the divinity of light?

Output: Pseudo-Dionysius

Input: Read this: Interstate 26 begins in downtown Charleston, with exits to the Septima Clark Expressway, the Arthur Ravenel, Jr. Bridge and Meeting Street. Heading northwest, it connects the city to North Charleston, the Charleston International Airport, Interstate 95, and Columbia. The Arthur Ravenel, Jr. Bridge and Septima Clark Expressway are part of U.S. Highway 17, which travels east-west through the cities of Charleston and Mount Pleasant. The Mark Clark Expressway, or Interstate 526, is the bypass around the city and begins and ends at U.S. Highway 17. U.S. Highway 52 is Meeting Street and its spur is East Bay Street, which becomes Morrison Drive after leaving the east side. This highway merges with King Street in the city's Neck area (industrial district). U.S. Highway 78 is King Street in the downtown area, eventually merging with Meeting Street.
Question: Interstate 562 begins and ends at what Highway?

Output: unanswerable

Input: Read this: The first successful light bulb filaments were made of carbon (from carbonized paper or bamboo). Early carbon filaments had a negative temperature coefficient of resistance as they got hotter, their electrical resistance decreased. This made the lamp sensitive to fluctuations in the power supply, since a small increase of voltage would cause the filament to heat up, reducing its resistance and causing it to draw even more power and heat even further. In the "flashing" process, carbon filaments were heated by current passing through them while in an evacuated vessel containing hydrocarbon vapor (usually gasoline). The carbon deposited on the filament by this treatment improved the uniformity and strength of filaments as well as their efficiency. A metallized or "graphitized" filament was first heated in a high-temperature oven before flashing and lamp assembly. This transformed the carbon into graphite which further strengthened and smoothed the filament. This also changed the filament to have a positive temperature coefficient, like a metallic conductor, and helped stabilize the lamp's power consumption, temperature and light output against minor variations in supply voltage.
Question: What material were the first light bulb filaments made from?

Output: carbon

Input: Read this: John XXIII was an advocate for human rights which included the unborn and the elderly. He wrote about human rights in his Pacem in terris. He wrote, "Man has the right to live. He has the right to bodily integrity and to the means necessary for the proper development of life, particularly food, clothing, shelter, medical care, rest, and, finally, the necessary social services. In consequence, he has the right to be looked after in the event of ill health; disability stemming from his work; widowhood; old age; enforced unemployment; or whenever through no fault of his own he is deprived of the means of livelihood."
Question: What are two groups that need the most services, according to widows?

Output:
