Question: The set of graphic and format characters defined by Unicode does not correspond directly to the repertoire of abstract characters that is representable under Unicode. Unicode encodes characters by associating an abstract character with a particular code point. However, not all abstract characters are encoded as a single Unicode character, and some abstract characters may be represented in Unicode by a sequence of two or more characters. For example, a Latin small letter "i" with an ogonek, a dot above, and an acute accent, which is required in Lithuanian, is represented by the character sequence U+012F, U+0307, U+0301. Unicode maintains a list of uniquely named character sequences for abstract characters that are not directly encoded in Unicode.
Try to answer this question if possible: What do sets of graphic characters directly correspond to?
Answer: unanswerable
Question: There is an environmental program, called Hoy No Circula ("Today Does Not Run", or "One Day without a Car"), whereby vehicles that have not passed emissions testing are restricted from circulating on certain days according to the ending digit of their license plates; this in an attempt to cut down on pollution and traffic congestion. While in 2003, the program still restricted 40% of vehicles in the metropolitan area, with the adoption of stricter emissions standards in 2001 and 2006, in practice, these days most vehicles are exempt from the circulation restrictions as long as they pass regular emissions tests.
Try to answer this question if possible: When were new emisson standards enacted?
Answer: 2006
Question: Many organisms (of which humans are prime examples) eat from multiple levels of the food chain and, thus, make this classification problematic. A carnivore may eat both secondary and tertiary consumers, and its prey may itself be difficult to classify for similar reasons. Organisms showing both carnivory and herbivory are known as omnivores. Even herbivores such as the giant panda may supplement their diet with meat. Scavenging of carrion provides a significant part of the diet of some of the most fearsome predators. Carnivorous plants would be very difficult to fit into this classification, producing their own food but also digesting anything that they may trap. Organisms that eat detritivores or parasites would also be difficult to classify by such a scheme.
Try to answer this question if possible: Would it be easy or difficult to classify organims that eat parasites in a food pyramid?
Answer: difficult
Question: The Strumica Carnival (Macedonian: Струмички Карневал, translated Strumichki Karneval) has been held since at least 1670, when the Turkish author Evlija Chelebija wrote while staying there, "I came into a town located in the foothills of a high hillock and what I saw that night was masked people running house–to–house, with laughter, scream and song." The Carnival took an organized form in 1991; in 1994, Strumica became a member of FECC and in 1998 hosted the XVIII International Congress of Carnival Cities. The Strumica Carnival opens on a Saturday night at a masked ball where the Prince and Princess are chosen; the main Carnival night is on Tuesday, when masked participants (including groups from abroad) compete in various subjects. As of 2000, the Festival of Caricatures and Aphorisms has been held as part of Strumica's Carnival celebrations.
Try to answer this question if possible: What year was the Festival of Caricatures and Aphorisms added to Strumica's Carnival celebrations?
