Context and question: The classical period of Greek civilization covers a time spanning from the early 5th century BC to the death of Alexander the Great, in 323 BC (some authors prefer to split this period into 'Classical', from the end of the Persian wars to the end of the Peloponnesian War, and 'Fourth Century', up to the death of Alexander). It is so named because it set the standards by which Greek civilization would be judged in later eras. The Classical period is also described as the "Golden Age" of Greek civilization, and its art, philosophy, architecture and literature would be instrumental in the formation and development of Western culture.

Context and question: 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.
What are officials seeking to do about protesting parents?
Answer:
limit protests
