Teacher:This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
Teacher: Now, understand the problem? Solve this instance: Passage: The 1970s saw many switches in diplomatic recognition from the Republic of China to the People's Republic of China. After World War II, the Republic of China had been one of the founding members in the United Nations and held China's seat on the Security Council until 1971, when it was expelled by General Assembly Resolution 2758 and replaced in all UN organs with the People's Republic of China government. Since the 1980s, the number of nations officially recognizing the Republic of China has decreased to 19. The People's Republic of China refuses to maintain diplomatic relations with any government which formally recognizes the Republic of China, leading to a complex political status of Taiwan . United States troops were stationed in Taiwan after the victory of the Communists in mainland China in order to aid in the defense of Taiwan against invasion by the People's Republic of China. The United States military continued to be stationed in Taiwan until diplomatic relations were broken with the Republic of China in 1979 but to this day maintains a significant intelligence presence.
Student:
How many nations recognize the Republic of China?
