Input: Read this: In times past, until the 15th century, in Korea, Literary Chinese was the dominant form of written communication, prior to the creation of hangul, the Korean alphabet. Much of the vocabulary, especially in the realms of science and sociology, comes directly from Chinese, comparable to Latin or Greek root words in European languages. However, due to the lack of tones in Korean,[citation needed] as the words were imported from Chinese, many dissimilar characters took on identical sounds, and subsequently identical spelling in hangul.[citation needed] Chinese characters are sometimes used to this day for either clarification in a practical manner, or to give a distinguished appearance, as knowledge of Chinese characters is considered a high class attribute and an indispensable part of a classical education.[citation needed] It is also observed that the preference for Chinese characters is treated as being conservative and Confucian.
Question: What is treated as being conservative and confucian?

Output: Chinese characters


Input: Read this: In 1951, during the early stages of the Cold War, Menzies spoke of the possibility of a looming third world war. The Menzies Government entered Australia's first formal military alliance outside of the British Commonwealth with the signing of the ANZUS Treaty between Australia, New Zealand and the United States in San Francisco in 1951. External Affairs Minister Percy Spender had put forward the proposal to work along similar lines to the NATO Alliance. The Treaty declared that any attack on one of the three parties in the Pacific area would be viewed as a threat to each, and that the common danger would be met in accordance with each nation's constitutional processes. In 1954 the Menzies Government signed the South East Asia Collective Defence Treaty (SEATO) as a South East Asian counterpart to NATO. That same year, Soviet diplomat Vladimir Petrov and his wife defected from the Soviet embassy in Canberra, revealing evidence of Russian spying activities; Menzies called a Royal Commission to investigate.
Question: What does the acronym did Percy Spender sign?

Output: unanswerable


Input: Read this: Several dozen radioisotopes have been characterized. 65Zn, which has a half-life of 243.66 days, is the most long-lived radioisotope, followed by 72Zn with a half-life of 46.5 hours. Zinc has 10 nuclear isomers. 69mZn has the longest half-life, 13.76 h. The superscript m indicates a metastable isotope. The nucleus of a metastable isotope is in an excited state and will return to the ground state by emitting a photon in the form of a gamma ray. 61Zn has three excited states and 73Zn has two. The isotopes 65Zn, 71Zn, 77Zn and 78Zn each have only one excited state.
Question: What is the longest half life of the isotopes?

Output: 243.66


Input: Read this: Participation in the Premier League by some Scottish or Irish clubs has sometimes been discussed, but without result.
