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.

[Q]: Passage: Acute myocardial infarction refers to two subtypes of acute coronary syndrome, namely non-ST-elevated and ST-elevated MIs, which are most frequently (but not always) a manifestation of coronary artery disease. The most common triggering event is the disruption of an atherosclerotic plaque in an epicardial coronary artery, which leads to a clotting cascade, sometimes resulting in total occlusion of the artery. Atherosclerosis is the gradual buildup of cholesterol and fibrous tissue in plaques in the wall of arteries (in this case, the coronary arteries), typically over decades. Bloodstream column irregularities visible on angiography reflect artery lumen narrowing as a result of decades of advancing atherosclerosis. Plaques can become unstable, rupture, and additionally promote the formation of a blood clot that occludes the artery; this can occur in minutes. When a severe enough plaque rupture occurs in the coronary arteries, it leads to MI (necrosis of downstream myocardium). It is estimated that one billion cardiac cells are lost in a typical MI.
[A]: How many subtypes does ST-elevated MI have?


[Q]: Passage: Some opponents further claim that affirmative action has undesirable side-effects and that it fails to achieve its goals. They argue that it hinders reconciliation, replaces old wrongs with new wrongs, undermines the achievements of minorities, and encourages groups to identify themselves as disadvantaged, even if they are not. It may increase racial tension and benefit the more privileged people within minority groups at the expense of the disenfranchised within better-off groups (such as lower-class whites and Asians).There has recently been a strong push among American states to ban racial or gender preferences in university admissions, in reaction to the controversial and unprecedented decision in Grutter v. Bollinger. In 2006, nearly 60% of Michigan voters decided to ban affirmative action in university admissions. Michigan joined California, Florida, Texas, and Washington in banning the use of race or sex in admissions considerations. Some opponents believe, among other things, that affirmative action devalues the accomplishments of people who belong to a group it's supposed to help, therefore making affirmative action counter-productive. Furthermore, opponents of affirmative action claim that these policies dehumanize individuals and applicants to jobs or school are judged as members of a group without consideration for the individual person.
[A]: Other than failing to achieve its goal, what else do people who agree with affirmative action claim it has?
