Input: Consider Input: Passage: On 30 September, Zhou Enlai warned the United States that China was prepared to intervene in Korea if the United States crossed the 38th parallel. Zhou attempted to advise North Korean commanders on how to conduct a general withdrawal by using the same tactics which had allowed Chinese communist forces to successfully escape Chiang Kai-shek's Encirclement Campaigns in the 1930s, but by some accounts North Korean commanders did not utilize these tactics effectively. Historian Bruce Cumings argues, however, the KPA's rapid withdrawal was strategic, with troops melting into the mountains from where they could launch guerrilla raids on the UN forces spread out on the coasts. Question: Who vowed to intervene if the US was to engage in conflict North of the 38th parallel?

Output: China


Input: Consider Input: Passage: Droney's health was poor and Kerry had decided to run for his position in the 1978 election should Droney drop out. However, Droney was re-elected and his health improved; he went on to re-assume many of the duties that he had delegated to Kerry. Kerry thus decided to leave, departing in 1979 with assistant DA Roanne Sragow to set up their own law firm. Kerry also worked as a commentator for WCVB-TV and co-founded a bakery, Kilvert & Forbes Ltd., with businessman and former Kennedy aide K. Dun Gifford. Question: Who left the DA's office with Kerry?

Output: Roanne Sragow


Input: Consider Input: Passage: Czech typographical features not associated with phonetics generally resemble those of most Latin European languages, including English. Proper nouns, honorifics, and the first letters of quotations are capitalized, and punctuation is typical of other Latin European languages. Writing of ordinal numerals is similar to most European languages. The Czech language uses a decimal comma instead of a decimal point. When writing a long number, spaces between every three numbers (e.g. between hundreds and thousands) may be used for better orientation in handwritten texts, but not in decimal places, like in English. The number 1,234,567.8910 may be written as 1234567,8910 or 1 234 567,8910. Ordinal numbers (1st) use a point as in German (1.). In proper noun phrases (except personal names), only the first word is capitalized (Pražský hrad, Prague Castle). Question: What word is capitalized in proper noun phrases in Czech?


Output: only the first
