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: The most-commonly accepted theory is that these events were triggered by the onset of an ice age, in the Hirnantian faunal stage that ended the long, stable greenhouse conditions typical of the Ordovician. The ice age was probably not as long-lasting as once thought; study of oxygen isotopes in fossil brachiopods shows that it was probably no longer than 0.5 to 1.5 million years. The event was preceded by a fall in atmospheric carbon dioxide (from 7000ppm to 4400ppm) which selectively affected the shallow seas where most organisms lived. As the southern supercontinent Gondwana drifted over the South Pole, ice caps formed on it. Evidence of these ice caps have been detected in Upper Ordovician rock strata of North Africa and then-adjacent northeastern South America, which were south-polar locations at the time.

Answer: What faunel stage triggered the greenhouse conditions of the Ordovician?


Question: Passage: Conventional bleaching of wood pulp using elemental chlorine produces and releases into the environment large amounts of chlorinated organic compounds, including chlorinated dioxins. Dioxins are recognized as a persistent environmental pollutant, regulated internationally by the Stockholm Convention on Persistent Organic Pollutants. Dioxins are highly toxic, and health effects on humans include reproductive, developmental, immune and hormonal problems. They are known to be carcinogenic. Over 90% of human exposure is through food, primarily meat, dairy, fish and shellfish, as dioxins accumulate in the food chain in the fatty tissue of animals.

Answer: What does bleaching of meat release into the environment?


Question: Passage: Everton F.C. is a limited company with the board of directors holding a majority of the shares. The club's most recent accounts, from May 2014, show a net total debt of £28.1 million, with a turnover of £120.5 million and a profit of £28.2 million. The club's overdraft with Barclays Bank is secured against the Premier League's "Basic Award Fund", a guaranteed sum given to clubs for competing in the Premier League. Everton agreed a long-term loan of £30 million with Bear Stearns and Prudential plc in 2002 over the duration of 25 years; a consolidation of debts at the time as well as a source of capital for new player acquisitions. Goodison Park is secured as collateral.

Answer:
How much profit did Everton F.C. have in 2002?
