Input: Read this: Solar technologies are broadly characterized as either passive or active depending on the way they capture, convert and distribute sunlight and enable solar energy to be harnessed at different levels around the world, mostly depending on distance from the equator. Although solar energy refers primarily to the use of solar radiation for practical ends, all renewable energies, other than geothermal and tidal, derive their energy from the Sun in a direct or indirect way.
Question: What is one way that characterizes solar technologies as passive or active?

Output: depending on the way they capture, convert and distribute sunlight


QUES: Coulton Waugh attempted the first comprehensive history of American comics with The Comics (1947). Will Eisner's Comics and Sequential Art (1985) and Scott McCloud's Understanding Comics (1993) were early attempts in English to formalize the study of comics. David Carrier's The Aesthetics of Comics (2000) was the first full-length treatment of comics from a philosophical perspective. Prominent American attempts at definitions of comics include Eisner's, McCloud's, and Harvey's. Eisner described what he called "sequential art" as "the arrangement of pictures or images and words to narrate a story or dramatize an idea"; Scott McCloud defined comics "juxtaposed pictorial and other images in deliberate sequence, intended to convey information and/or to produce an aesthetic response in the viewer", a strictly formal definition which detached comics from its historical and cultural trappings. R. C. Harvey defined comics as "pictorial narratives or expositions in which words (often lettered into the picture area within speech balloons) usually contribute to the meaning of the pictures and vice versa". Each definition has had its detractors. Harvey saw McCloud's definition as excluding single-panel cartoons, and objected to McCloud's de-emphasizing verbal elements, insisting "the essential characteristic of comics is the incorporation of verbal content". Aaron Meskin saw McCloud's theories as an artificial attempt to legitimize the place of comics in art history.

QUES: Island genetics provides one proposed explanation for the sudden, fully developed appearance of flowering plants. Island genetics is believed to be a common source of speciation in general, especially when it comes to radical adaptations that seem to have required inferior transitional forms. Flowering plants may have evolved in an isolated setting like an island or island chain, where the plants bearing them were able to develop a highly specialized relationship with some specific animal (a wasp, for example). Such a relationship, with a hypothetical wasp carrying pollen from one plant to another much the way fig wasps do today, could result in the development of a high degree of specialization in both the plant(s) and their partners. Note that the wasp example is not incidental; bees, which, it is postulated, evolved specifically due to mutualistic plant relationships, are descended from wasps.
What is one proposed explanation for the instant appearance of flowering plants?

ANS: Island genetics


De novo or "orphan" genes, whose sequence shows no similarity to existing genes, are extremely rare. Estimates of the number of de novo genes in the human genome range from 18 to 60. Such genes are typically shorter and simpler in structure than most eukaryotic genes, with few if any introns. Two primary sources of orphan protein-coding genes are gene duplication followed by extremely rapid sequence change, such that the original relationship is undetectable by sequence comparisons, and formation through mutation of "cryptic" transcription start sites that introduce a new open reading frame in a region of the genome that did not previously code for a protein.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is one primary source of orphan protein-coding genes?
Ah, so.. gene duplication followed by extremely rapid sequence change


Question: Alloying a metal is done by combining it with one or more other metals or non-metals that often enhance its properties. For example, steel is stronger than iron, its primary element. The electrical and thermal conductivity of alloys is usually lower than that of the pure metals. The physical properties, such as density, reactivity, Young's modulus of an alloy may not differ greatly from those of its elements, but engineering properties such as tensile strength and shear strength may be substantially different from those of the constituent materials. This is sometimes a result of the sizes of the atoms in the alloy, because larger atoms exert a compressive force on neighboring atoms, and smaller atoms exert a tensile force on their neighbors, helping the alloy resist deformation. Sometimes alloys may exhibit marked differences in behavior even when small amounts of one element are present. For example, impurities in semiconducting ferromagnetic alloys lead to different properties, as first predicted by White, Hogan, Suhl, Tian Abrie and Nakamura. Some alloys are made by melting and mixing two or more metals. Bronze, an alloy of copper and tin, was the first alloy discovered, during the prehistoric period now known as the bronze age; it was harder than pure copper and originally used to make tools and weapons, but was later superseded by metals and alloys with better properties. In later times bronze has been used for ornaments, bells, statues, and bearings. Brass is an alloy made from copper and zinc.
Try to answer this question if possible: What is combined with tin to make brass?
Answer: unanswerable


Input: Read this: Due to the inter-communal ethnic tensions between 1963 and 1974, an island-wide census was regarded as impossible. Nevertheless, the Greek Cypriots conducted one in 1973, without the Turkish Cypriot populace. According to this census, the Greek Cypriot population was 482,000. One year later, in 1974, the Cypriot government's Department of Statistics and Research estimated the total population of Cyprus at 641,000; of whom 506,000 (78.9%) were Greeks, and 118,000 (18.4%) Turkish. After the partition of the island in 1974, Greeks conducted four more censuses: in 1976, 1982, 1992 and 2001; these excluded the Turkish population which was resident in the northern part of the island.
Question: In what years did the Greeks conduct extra censuses?

Output:
1976, 1982, 1992 and 2001
