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.

Input: Consider Input: Passage: The terms used to define Greekness have varied throughout history but were never limited or completely identified with membership to a Greek state. By Western standards, the term Greeks has traditionally referred to any native speakers of the Greek language, whether Mycenaean, Byzantine or modern Greek. Byzantine Greeks called themselves Romioi and considered themselves the political heirs of Rome, but at least by the 12th century a growing number of those educated, deemed themselves the heirs of ancient Greece as well, although for most of the Greek speakers, "Hellene" still meant pagan. On the eve of the Fall of Constantinople the Last Emperor urged his soldiers to remember that they were the descendants of Greeks and Romans.

Output: What do Easterners believe it means to belong to the Greek heritage


Input: Consider Input: Passage: From 1997 to 2004, Dell enjoyed steady growth and it gained market share from competitors even during industry slumps. During the same period, rival PC vendors such as Compaq, Gateway, IBM, Packard Bell, and AST Research struggled and eventually left the market or were bought out. Dell surpassed Compaq to become the largest PC manufacturer in 1999. Operating costs made up only 10 percent of Dell's $35 billion in revenue in 2002, compared with 21 percent of revenue at Hewlett-Packard, 25 percent at Gateway, and 46 percent at Cisco. In 2002, when Compaq merged with Hewlett Packard (the fourth-place PC maker), the newly combined Hewlett Packard took the top spot but struggled and Dell soon regained its lead. Dell grew the fastest in the early 2000s.

Output: What did Dell enjoy from 1996 to 2004?


Input: Consider Input: Passage: Several campus safety strategies have been pioneered at Yale. The first campus police force was founded at Yale in 1894, when the university contracted city police officers to exclusively cover the campus. Later hired by the university, the officers were originally brought in to quell unrest between students and city residents and curb destructive student behavior. In addition to the Yale Police Department, a variety of safety services are available including blue phones, a safety escort, and 24-hour shuttle service.


Output: When were the last campus police formed at Yale?
