This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Example Input: Passage: To make pulp from wood, a chemical pulping process separates lignin from cellulose fibres. This is accomplished by dissolving lignin in a cooking liquor, so that it may be washed from the cellulose; this preserves the length of the cellulose fibres. Paper made from chemical pulps are also known as wood-free papers–not to be confused with tree-free paper; this is because they do not contain lignin, which deteriorates over time. The pulp can also be bleached to produce white paper, but this consumes 5% of the fibres; chemical pulping processes are not used to make paper made from cotton, which is already 90% cellulose.
Example Output: What is separated from pulp to make wood?

Example Input: Passage: Sky UK Limited (formerly British Sky Broadcasting or BSkyB) is a British telecommunications company which serves the United Kingdom. Sky provides television and broadband internet services and fixed line telephone services to consumers and businesses in the United Kingdom. It is the UK's largest pay-TV broadcaster with 11 million customers as of 2015. It was the UK's most popular digital TV service until it was overtaken by Freeview in April 2007. Its corporate headquarters are based in Isleworth.
Example Output: Sky UK Limited is now known by what name?

Example Input: Passage: After the People's Republic of China took control of Mainland China in 1949, the Republic of China government based in Taiwan continued to control the Dachen Islands off the coast of Zhejiang until 1955, even establishing a rival Zhejiang provincial government there, creating a situation similar to Fujian province today. During the Cultural Revolution (1966–76), Zhejiang was in chaos and disunity, and its economy was stagnant, especially during the high tide (1966–69) of the revolution. The agricultural policy favoring grain production at the expense of industrial and cash crops intensified economic hardships in the province. Mao’s self-reliance policy and the reduction in maritime trade cut off the lifelines of the port cities of Ningbo and Wenzhou. While Mao invested heavily in railroads in interior China, no major railroads were built in South Zhejiang, where transportation remained poor.
Example Output:
What happened in 1944?
