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.

Question: Passage: In September 2003, a new type of blue LED was demonstrated by Cree that consumes 24 mW at 20 milliamperes (mA). This produced a commercially packaged white light giving 65 lm/W at 20 mA, becoming the brightest white LED commercially available at the time, and more than four times as efficient as standard incandescents. In 2006, they demonstrated a prototype with a record white LED luminous efficacy of 131 lm/W at 20 mA. Nichia Corporation has developed a white LED with luminous efficacy of 150 lm/W at a forward current of 20 mA. Cree's XLamp XM-L LEDs, commercially available in 2011, produce 100 lm/W at their full power of 10 W, and up to 160 lm/W at around 2 W input power. In 2012, Cree announced a white LED giving 254 lm/W, and 303 lm/W in March 2014. Practical general lighting needs high-power LEDs, of one watt or more. Typical operating currents for such devices begin at 350 mA.

Answer:  In what year was a new type of red LED produced?


Question: Passage: The formula defining the HDI is promulgated by the United Nations Development Programme (UNDP). In general, to transform a raw variable, say , into a unit-free index between 0 and 1 (which allows different indices to be added together), the following formula is used:

Answer:  What entity makes the defining formula for the HDMI well-known?


Question: Passage: The city is also home to the Heineken Brewery that brews Murphy's Irish Stout and the nearby Beamish and Crawford brewery (taken over by Heineken in 2008) which have been in the city for generations. 45% of the world's Tic Tac sweets are manufactured at the city's Ferrero factory. For many years, Cork was the home to Ford Motor Company, which manufactured cars in the docklands area before the plant was closed in 1984. Henry Ford's grandfather was from West Cork, which was one of the main reasons for opening up the manufacturing facility in Cork. But technology has replaced the old manufacturing businesses of the 1970s and 1980s, with people now working in the many I.T. centres of the city – such as Amazon.com, the online retailer, which has set up in Cork Airport Business Park.

Answer:
What brewery took over Heineken in 2008?
