Input: Read this: The New York Times reported that "government officials in Beijing and Sichuan have said they are investigating the collapses. In an acknowledgment of the weakness of building codes in the countryside, the National Development and Reform Commission said on May 27 that it had drafted an amendment to improve construction standards for primary and middle schools in rural areas. Experts are reviewing the draft, the commission said." To limit protests, officials pushed parents to sign a document, which forbade them from holding protests, in exchange of money, but some who refused to sign were threatened. The payment amounts varied from school to school but were approximately the same. In Hanwang, parents were offered a package valued at 8,800 USD in cash and a per-parent pension of nearly 5,600 USD. Furthermore, officials used other methods of silencing: riot police officers broke up protests by parents; the authorities set up cordons around the schools; and officials ordered the Chinese news media to stop reporting on school collapses.
Question: Who did the New York Times report was investigating the school collapses?

Input: Read this: Inappropriate antibiotic treatment and overuse of antibiotics have contributed to the emergence of antibiotic-resistant bacteria. Self prescription of antibiotics is an example of misuse. Many antibiotics are frequently prescribed to treat symptoms or diseases that do not respond to antibiotics or that are likely to resolve without treatment. Also, incorrect or suboptimal antibiotics are prescribed for certain bacterial infections. The overuse of antibiotics, like penicillin and erythromycin, has been associated with emerging antibiotic resistance since the 1950s. Widespread usage of antibiotics in hospitals has also been associated with increases in bacterial strains and species that no longer respond to treatment with the most common antibiotics.
Question: What as been associated with increases in suboptimal antibiotics?

Output: unanswerable

Input: Read this: Cork was originally a monastic settlement, reputedly founded by Saint Finbarr in the 6th century. Cork achieved an urban character at some point between 915 and 922 when Norseman (Viking) settlers founded a trading port. It has been proposed that, like Dublin, Cork was an important trading centre in the global Scandinavian trade network. The ecclesiastical settlement continued alongside the Viking longphort, with the two developing a type of symbiotic relationship; the Norsemen providing otherwise unobtainable trade goods for the monastery, and perhaps also military aid.
Question: When did Viking travelers establish a trading post in Cork?

Output:
some point between 915 and 922
