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: Iron is usually found as iron ore on Earth, except for one deposit of native iron in Greenland, which was used by the Inuit people. Native copper, however, was found worldwide, along with silver, gold and platinum, which were also used to make tools, jewelry, and other objects since Neolithic times. Copper was the hardest of these metals, and the most widely distributed. It became one of the most important metals to the ancients. Eventually, humans learned to smelt metals such as copper and tin from ore, and, around 2500 BC, began alloying the two metals to form bronze, which is much harder than its ingredients. Tin was rare, however, being found mostly in Great Britain. In the Middle East, people began alloying copper with zinc to form brass. Ancient civilizations took into account the mixture and the various properties it produced, such as hardness, toughness and melting point, under various conditions of temperature and work hardening, developing much of the information contained in modern alloy phase diagrams. Arrowheads from the Chinese Qin dynasty (around 200 BC) were often constructed with a hard bronze-head, but a softer bronze-tang, combining the alloys to prevent both dulling and breaking during use.

Output: What is usually found his iron ore in Greenland?


Input: Consider Input: Passage: Pomors are distinguished by the presence of Y Haplogroup N among them. Postulated to originate from southeast Asia, it is found at high rates in Uralic peoples. Its presence in Pomors (called "Northern Russians" in the report) attests to the non-Slavic tribes (mixing with Finnic tribes of northern Eurasia). Autosomally, Russians are generally similar to populations in central-eastern Europe but some northern Russians are intermediate to Finno-Ugric groups.

Output: What are Y Haplogroup N distinguished by?


Input: Consider Input: Passage: Dell opened plants in Penang, Malaysia in 1995, and in Xiamen, China in 1999. These facilities serve the Asian market and assemble 95% of Dell notebooks. Dell Inc. has invested[when?] an estimated $60 million in a new manufacturing unit in Chennai, India, to support the sales of its products in the Indian subcontinent. Indian-made products bear the "Made in India" mark. In 2007 the Chennai facility had the target of producing 400,000 desktop PCs, and plans envisaged it starting to produce notebook PCs and other products in the second half of 2007.[citation needed]


Output: In what foreign country did Dell close plants in 1995?
