Input: Read this: The use of traditional Chinese characters versus simplified Chinese characters varies greatly, and can depend on both the local customs and the medium. Before the official reform, character simplifications were not officially sanctioned and generally adopted vulgar variants and idiosyncratic substitutions. Orthodox variants were mandatory in printed works, while the (unofficial) simplified characters would be used in everyday writing or quick notes. Since the 1950s, and especially with the publication of the 1964 list, the People's Republic of China has officially adopted simplified Chinese characters for use in mainland China, while Hong Kong, Macau, and the Republic of China (Taiwan) were not affected by the reform. There is no absolute rule for using either system, and often it is determined by what the target audience understands, as well as the upbringing of the writer.
Question: What were mandatory in printed works?

Output: Orthodox variants


QUES: Other scholars[who?] suggest that these arguments are flawed, ignores history and more laws will do more harm than good. According to them, child labour is merely the symptom of a greater disease named poverty. If laws ban all lawful work that enables the poor to survive, informal economy, illicit operations and underground businesses will thrive. These will increase abuse of the children. In poor countries with very high incidence rates of child labour - such as Ethiopia, Chad, Niger and Nepal - schools are not available, and the few schools that exist offer poor quality education or are unaffordable. The alternatives for children who currently work, claim these studies, are worse: grinding subsistence farming, militia or prostitution. Child labour is not a choice, it is a necessity, the only option for survival. It is currently the least undesirable of a set of very bad choices.

What do some scholars agress is the "disease" of child labour?
What is the answer?
ANS: poverty


QUES: Despite some concerns, western vegetarians and vegans have not been found to suffer from overt zinc deficiencies any more than meat-eaters. Major plant sources of zinc include cooked dried beans, sea vegetables, fortified cereals, soyfoods, nuts, peas, and seeds. However, phytates in many whole-grains and fiber in many foods may interfere with zinc absorption and marginal zinc intake has poorly understood effects. The zinc chelator phytate, found in seeds and cereal bran, can contribute to zinc malabsorption. There is some evidence to suggest that more than the US RDA (15 mg) of zinc daily may be needed in those whose diet is high in phytates, such as some vegetarians. These considerations must be balanced against the fact that there is a paucity of adequate zinc biomarkers, and the most widely used indicator, plasma zinc, has poor sensitivity and specificity. Diagnosing zinc deficiency is a persistent challenge.
What is the only way that vegetarians and vegans obtain zinc?

ANS: unanswerable


GE is a multinational conglomerate headquartered in Fairfield, Connecticut. Its main offices are located at 30 Rockefeller Plaza at Rockefeller Center in New York City, known now as the Comcast Building. It was formerly known as the GE Building for the prominent GE logo on the roof; NBC's headquarters and main studios are also located in the building. Through its RCA subsidiary, it has been associated with the center since its construction in the 1930s. GE moved its corporate headquarters from the GE Building on Lexington Avenue to Fairfield in 1974.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which television broadcast company is located in the same building as GE's main offices in New York City?
Ah, so.. NBC


Question: For example, consider electron–positron annihilation, in which the rest mass of individual particles is destroyed, but the inertia equivalent of the system of the two particles (its invariant mass) remains (since all energy is associated with mass), and this inertia and invariant mass is carried off by photons which individually are massless, but as a system retain their mass. This is a reversible process – the inverse process is called pair creation – in which the rest mass of particles is created from energy of two (or more) annihilating photons. In this system the matter (electrons and positrons) is destroyed and changed to non-matter energy (the photons). However, the total system mass and energy do not change during this interaction.
Try to answer this question if possible: What is it called when the rest mass of individual particles is destroyed but the inertia equivalent of the system of the three particles remains?
Answer: unanswerable


Context and question: In ancient Greece, the epics of Homer, who wrote the Iliad and the Odyssey, and Hesiod, who wrote Works and Days and Theogony, are some of the earliest, and most influential, of Ancient Greek literature. Classical Greek genres included philosophy, poetry, historiography, comedies and dramas. Plato and Aristotle authored philosophical texts that are the foundation of Western philosophy, Sappho and Pindar were influential lyric poets, and Herodotus and Thucydides were early Greek historians. Although drama was popular in Ancient Greece, of the hundreds of tragedies written and performed during the classical age, only a limited number of plays by three authors still exist: Aeschylus, Sophocles, and Euripides. The plays of Aristophanes provide the only real examples of a genre of comic drama known as Old Comedy, the earliest form of Greek Comedy, and are in fact used to define the genre.
What still exists written by Aeschylus, Sophocles, and Plato?
