Problem: Please answer a question about the following article about Unicode:
Injective mappings must be provided between characters in existing legacy character sets and characters in Unicode to facilitate conversion to Unicode and allow interoperability with legacy software. Lack of consistency in various mappings between earlier Japanese encodings such as Shift-JIS or EUC-JP and Unicode led to round-trip format conversion mismatches, particularly the mapping of the character JIS X 0208 '~' (1-33, WAVE DASH), heavily used in legacy database data, to either U+FF5E ~ FULLWIDTH TILDE (in Microsoft Windows) or U+301C WAVE DASH (other vendors).
What kind of mappings must be provided between characters in existing legacy character sets and those in Unicode?
A: Injective mappings
Problem: Please answer a question about the following article about Han dynasty:
Three Han mathematical treatises still exist. These are the Book on Numbers and Computation, the Arithmetical Classic of the Gnomon and the Circular Paths of Heaven and the Nine Chapters on the Mathematical Art. Han-era mathematical achievements include solving problems with right-angle triangles, square roots, cube roots, and matrix methods, finding more accurate approximations for pi, providing mathematical proof of the Pythagorean theorem, use of the decimal fraction, Gaussian elimination to solve linear equations, and continued fractions to find the roots of equations.
How many mathematical treatises have still managed to survive to this day?
A: Three
Problem: Please answer a question about the following article about Gamal Abdel Nasser:
On 18 June 1953, the monarchy was abolished and the Republic of Egypt declared, with Naguib as its first president. According to Aburish, after assuming power, Nasser and the Free Officers expected to become the "guardians of the people's interests" against the monarchy and the pasha class while leaving the day-to-day tasks of government to civilians. They asked former prime minister Ali Maher to accept reappointment to his previous position, and to form an all-civilian cabinet. The Free Officers then governed as the Revolutionary Command Council (RCC) with Naguib as chairman and Nasser as vice-chairman. Relations between the RCC and Maher grew tense, however, as the latter viewed many of Nasser's schemesagrarian reform, abolition of the monarchy, reorganization of political partiesas too radical, culminating in Maher's resignation on 7 September. Naguib assumed the additional role of prime minister, and Nasser that of deputy prime minister. In September, the Agrarian Reform Law was put into effect. In Nasser's eyes, this law gave the RCC its own identity and transformed the coup into a revolution.
Who did Nasser recruit to be Prime Minister?
A: Ali Maher
Problem: Please answer a question about the following article about Cubism:
The reemergence of Cubism coincided with the appearance from about 191724 of a coherent body of theoretical writing by Pierre Reverdy, Maurice Raynal and Daniel-Henry Kahnweiler and, among the artists, by Gris, Leger and Gleizes. The occasional return to classicismfigurative work either exclusively or alongside Cubist workexperienced by many artists during this period (called Neoclassicism) has been linked to the tendency to evade the realities of the war and also to the cultural dominance of a classical or Latin image of France during and immediately following the war. Cubism after 1918 can be seen as part of a wide ideological shift towards conservatism in both French society and culture. Yet, Cubism itself remained evolutionary both within the oeuvre of individual artists, such as Gris and Metzinger, and across the work of artists as different from each other as Braque, Leger and Gleizes. Cubism as a publicly debated movement became relatively unified and open to definition. Its theoretical purity made it a gauge against which such diverse tendencies as Realism or Naturalism, Dada, Surrealism and abstraction could be compared.
Name the three writers who were in part resonsible for the reemergence of Cubism between 1917 and 1924.
A:
Pierre Reverdy, Maurice Raynal and Daniel-Henry Kahnweiler
