Input: Read this: Because Czech uses grammatical case to convey word function in a sentence (instead of relying on word order, as English does), its word order is flexible. As a pro-drop language, in Czech an intransitive sentence can consist of only a verb; information about its subject is encoded in the verb. Enclitics (primarily auxiliary verbs and pronouns) must appear in the second syntactic slot of a sentence, after the first stressed unit. The first slot must contain a subject and object, a main form of a verb, an adverb or a conjunction (except for the light conjunctions a, "and", i, "and even" or ale, "but").
Question: Czech's word order is flexible because it uses what to convey word function in a sentence?

Output: grammatical case

QUES: Von Neumann was born Neumann Janos Lajos (in Hungarian the family name comes first), Hebrew name Yonah, in Budapest, Kingdom of Hungary, which was then part of the Austro-Hungarian Empire, to wealthy Jewish parents of the Haskalah. He was the eldest of three children. He had two younger brothers: Michael, born in 1907, and Nicholas, who was born in 1911. His father, Neumann Miksa (Max Neumann) was a banker, who held a doctorate in law. He had moved to Budapest from Pecs at the end of the 1880s.

The growing likelihood of war in Europe dominated the early reign of George VI. The King was constitutionally bound to support Prime Minister Neville Chamberlain's appeasement of Hitler. However, when the King and Queen greeted Chamberlain on his return from negotiating the Munich Agreement in 1938, they invited him to appear on the balcony of Buckingham Palace with them. This public association of the monarchy with a politician was exceptional, as balcony appearances were traditionally restricted to the royal family. While broadly popular among the general public, Chamberlain's policy towards Hitler was the subject of some opposition in the House of Commons, which led historian John Grigg to describe the King's behaviour in associating himself so prominently with a politician as "the most unconstitutional act by a British sovereign in the present century".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which agreement was signed in 1938?
Ah, so.. Munich Agreement

Question: Following the events in Olympia, there were reports that China requested permission to deploy People's Liberation Army personnel along the relay route to protect the flame in Canberra. Australian authorities stated that such a request, if it were to be made, would be refused. Chinese officials labeled it a rumor. Australian police have been given powers to search relay spectators, following a call by the Chinese Students and Scholars Association for Chinese Australian students to "go defend our sacred torch" against "ethnic degenerate scum and anti-China separatists". Tony Goh, chairman of the Australian Council of Chinese Organisations, has said the ACCO would be taking "thousands" of pro-Beijing demonstrators to Canberra by bus, to support the torch relay. Zhang Rongan, a Chinese Australian student organising pro-Beijing demonstrations, told the press that Chinese diplomats were assisting with the organization of buses, meals and accommodation for pro-Beijing demonstrators, and helping them organise a "peaceful show of strength". Foreign Minister Stephen Smith said Chinese officials were urging supporters to "turn up and put a point of view", but that he had no objection to it as long as they remained peaceful.
Try to answer this question if possible: Who was the Foreign Minister who indicated Chinese officials wanted supporting demonstrators to show up and show their point of view?
Answer: Stephen Smith

Problem: At this time, Britain and France became bitter rivals. Frequent skirmishes between them took place for control of colonial possessions. In 1742, fearing the monetary consequences of a war, the British government agreed to extend the deadline for the licensed exclusive trade by the company in India until 1783, in return for a further loan of 1 million. Between 1756 and 1763, the Seven Years' War diverted the state's attention towards consolidation and defence of its territorial possessions in Europe and its colonies in North America.
What was irrelevant that brought the British government to extend the deadline for the trade license for the company?
