Extract the answer to the question from the following context. Question: Why did government official intimidate some parents? Context: 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.
Ans: refused to sign

Extract the answer to the question from the following context. Question: How was Hugo Grotius able to teach his natural-law theory? Context: Politically, Calvin favoured a mixture of aristocracy and democracy. He appreciated the advantages of democracy: "It is an invaluable gift, if God allows a people to freely elect its own authorities and overlords." Calvin also thought that earthly rulers lose their divine right and must be put down when they rise up against God. To further protect the rights of ordinary people, Calvin suggested separating political powers in a system of checks and balances (separation of powers). Thus he and his followers resisted political absolutism and paved the way for the rise of modern democracy. Besides England, the Netherlands were, under Calvinist leadership, the freest country in Europe in the seventeenth and eighteenth centuries. It granted asylum to philosophers like Baruch Spinoza and Pierre Bayle. Hugo Grotius was able to teach his natural-law theory and a relatively liberal interpretation of the Bible.
Ans: Netherlands were, under Calvinist leadership, the freest country in Europe

Extract the answer to the question from the following context. Question: What evidence is used as a rubric for critics? Context: When comparing different documents, or "witnesses", of a single, original text, the observed differences are called variant readings, or simply variants or readings. It is not always apparent which single variant represents the author's original work. The process of textual criticism seeks to explain how each variant may have entered the text, either by accident (duplication or omission) or intention (harmonization or censorship), as scribes or supervisors transmitted the original author's text by copying it. The textual critic's task, therefore, is to sort through the variants, eliminating those most likely to be un-original, hence establishing a "critical text", or critical edition, that is intended to best approximate the original. At the same time, the critical text should document variant readings, so the relation of extant witnesses to the reconstructed original is apparent to a reader of the critical edition. In establishing the critical text, the textual critic considers both "external" evidence (the age, provenance, and affiliation of each witness) and "internal" or "physical" considerations (what the author and scribes, or printers, were likely to have done).
Ans: both "external" evidence (the age, provenance, and affiliation of each witness) and "internal" or "physical" considerations

Extract the answer to the question from the following context. Question: Which terraces don't have roof? Context: Widely referred to as Highbury, Arsenal Stadium was the club's home from September 1913 until May 2006. The original stadium was designed by the renowned football architect Archibald Leitch, and had a design common to many football grounds in the UK at the time, with a single covered stand and three open-air banks of terracing. The entire stadium was given a massive overhaul in the 1930s: new Art Deco West and East stands were constructed, opening in 1932 and 1936 respectively, and a roof was added to the North Bank terrace, which was bombed during the Second World War and not restored until 1954.
Ans: West and East stands
