TASK DEFINITION: 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.
PROBLEM: Passage: Other less likely contenders are Guam and the United States Virgin Islands, both of which are unincorporated organized territories of the United States. Also, the Northern Mariana Islands and American Samoa, an unorganized, unincorporated territory, could both attempt to gain statehood. Some proposals call for the Virgin Islands to be admitted with Puerto Rico as one state (often known as the proposed "Commonwealth of Prusvi", for Puerto Rico/U.S. Virgin Islands, or as "Puerto Virgo"), and for the amalgamation of U.S. territories or former territories in the Pacific Ocean, in the manner of the "Greater Hawaii" concept of the 1960s. Guam and the Northern Mariana Islands would be admitted as one state, along with Palau, the Federated States of Micronesia, and the Marshall Islands (although these latter three entities are now separate sovereign nations, which have Compact of Free Association relationships with the United States). Such a state would have a population of 412,381 (slightly lower than Wyoming's population) and a land area of 911.82 square miles (2,361.6 km2) (slightly smaller than Rhode Island). American Samoa could possibly be part of such a state, increasing the population to 467,900 and the area to 988.65 square miles (2,560.6 km2). Radio Australia, in late May 2008, issued signs of Guam and the Northern Mariana Islands becoming one again and becoming the 51st state.

SOLUTION: What is another likely country for free association?

PROBLEM: Passage: Ann Arbor is a major scene of college sports, most notably at the University of Michigan, a member of the Big Ten Conference. Several well-known college sports facilities exist in the city, including Michigan Stadium, the largest American football stadium in the world. The stadium was completed in 1927 and cost more than $950,000 to build. It has a 109,901 seating capacity after multiple renovations were made. The stadium is colloquially known as "The Big House". Crisler Center and Yost Ice Arena play host to the school's basketball (both men's and women's) and ice hockey teams, respectively. Concordia University, a member of the NAIA, also fields sports teams.

SOLUTION: What stadium was completed in 1972?

PROBLEM: Passage: Exercise can trigger bronchoconstriction both in people with or without asthma. It occurs in most people with asthma and up to 20% of people without asthma. Exercise-induced bronchoconstriction is common in professional athletes. The highest rates are among cyclists (up to 45%), swimmers, and cross-country skiers. While it may occur with any weather conditions it is more common when it is dry and cold. Inhaled beta2-agonists do not appear to improve athletic performance among those without asthma however oral doses may improve endurance and strength.

SOLUTION:
What does exercise trigger in people who use inhaled beta2 agonists?
