Input: Read this: While forming an integral part of the Christian calendar, particularly in Catholic regions, many Carnival traditions resemble those antedating Christianity. Italian Carnival is sometimes thought to be derived from the ancient Roman festivals of Saturnalia and Bacchanalia. The Saturnalia, in turn, may be based on the Greek Dionysia and Oriental festivals. For the start of the Roman Saturnalia, on December 17 authorities chose an enemy of the Roman people to represent the Lord of Misrule in each community. These men and women were forced to indulge in food and physical pleasures throughout the week, horribly murdered on December 25th: "destroying the forces of darkness".
Question: Many Carnival traditions form an integral part of whose calendar?

Output: Christian


Input: Read this: However, Avicenna posited the brain as the place where reason interacts with sensation. Sensation prepares the soul to receive rational concepts from the universal Agent Intellect. The first knowledge of the flying person would be "I am," affirming his or her essence. That essence could not be the body, obviously, as the flying person has no sensation. Thus, the knowledge that "I am" is the core of a human being: the soul exists and is self-aware. Avicenna thus concluded that the idea of the self is not logically dependent on any physical thing, and that the soul should not be seen in relative terms, but as a primary given, a substance. The body is unnecessary; in relation to it, the soul is its perfection. In itself, the soul is an immaterial substance.
Question: What is dependent on a physical thing?

Output: unanswerable


Input: Read this: Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness.
Question: What can improve the efficiency of non-LED-based white light?

Output: unanswerable


Input: Read this: Glass is in widespread use largely due to the production of glass compositions that are transparent to visible light. In contrast, polycrystalline materials do not generally transmit visible light. The individual crystallites may be transparent, but their facets (grain boundaries) reflect or scatter light resulting in diffuse reflection. Glass does not contain the internal subdivisions associated with grain boundaries in polycrystals and hence does not scatter light in the same manner as a polycrystalline material. The surface of a glass is often smooth since during glass formation the molecules of the supercooled liquid are not forced to dispose in rigid crystal geometries and can follow surface tension, which imposes a microscopically smooth surface. These properties, which give glass its clearness, can be retained even if glass is partially light-absorbing—i.e., colored.
Question: What type of glass absorbs molecules of supercooled liquid?

Output:
unanswerable
