Input: Read this: It is generally considered that the Pacific War began on 7/8 December 1941, on which date Japan invaded Thailand and attacked the British possessions of Malaya, Singapore, and Hong Kong as well as the United States military bases in Hawaii, Wake Island, Guam and the Philippines. Some historians contend that the conflict in Asia can be dated back to 7 July 1937 with the beginning of the Second Sino-Japanese War between the Empire of Japan and the Republic of China, or possibly 19 September 1931, beginning with the Japanese invasion of Manchuria. However, it is more widely accepted that the Pacific War itself started in early December 1941, with the Sino-Japanese War then becoming part of it as a theater of the greater World War II.[nb 9]
Question: What nation initiated hostilities?

Output: Japan

Input: Read this: With advances in medicinal chemistry, most modern antibacterials are semisynthetic modifications of various natural compounds. These include, for example, the beta-lactam antibiotics, which include the penicillins (produced by fungi in the genus Penicillium), the cephalosporins, and the carbapenems. Compounds that are still isolated from living organisms are the aminoglycosides, whereas other antibacterialsfor example, the sulfonamides, the quinolones, and the oxazolidinonesare produced solely by chemical synthesis. Many antibacterial compounds are relatively small molecules with a molecular weight of less than 2000 atomic mass units.[citation needed]
Question: What is the molecular weight loss of chemical synthesis?

Output: unanswerable

Input: Read this: Some scholars believe that Modern Orthodoxy arose from the religious and social realities of Western European Jewry. While most Jews consider Modern Orthodoxy traditional today, some (the hareidi and hasidic groups) within the Orthodox community consider some elements to be of questionable validity. The neo-Orthodox movement holds that Hirsch's views are not accurately followed by Modern Orthodoxy. [See Torah im Derech Eretz and Torah Umadda "Relationship with Torah im Derech Eretz" for a more extensive listing.]
Question: Who considers modern orthodoxy to have completely valid elements?

Output: unanswerable

Input: Read this: The port on Montevideo Bay is one of the reasons the city was founded. It gives natural protection to ships, although two jetties now further protect the harbour entrance from waves. This natural port is competitive with the other great port of Rio de la Plata, Buenos Aires. The main engineering work on the port occurred between the years 1870 and 1930. These six decades saw the construction of the port's first wooden pier, several warehouses in La Aguada, the north and south Rambla, a river port, a new pier, the dredged river basin and the La Teja refinery. A major storm in 1923 necessitated repairs to many of the city's engineering works. Since the second half of the 20th century, physical changes have ceased, and since that time the area has degraded due to national economic stagnation.
Question: What happened in 1923 that required repairs to many of the city's engineering works?

Output:
A major storm
