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: 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.

Answer: How many subtypes does ST-elevated MI have?

Question: Passage: BYU has been considered by some Latter-day Saints, as well as some university and church leaders, to be "The Lord's university". This phrase is used in reference to the school's mission as an "ambassador" to the world for the LDS Church and thus, for Jesus Christ. In the past, some students and faculty have expressed dissatisfaction with this nickname, stating that it gives students the idea that university authorities are always divinely inspired and never to be contradicted. Leaders of the school, however, acknowledge that the nickname represents more a goal that the university strives for and not its current state of being. Leaders encourage students and faculty to help fulfill the goal by following the teachings of their religion, adhering to the school's honor code, and serving others with the knowledge they gain while attending.

Answer: What is BUY considered to be by some?

Question: Passage: In ancient India, literature originated from stories that were originally orally transmitted. Early genres included drama, fables, sutras and epic poetry. Sanskrit literature begins with the Vedas, dating back to 15001000 BCE, and continues with the Sanskrit Epics of Iron Age India. The Vedas are among the oldest sacred texts. The Samhitas (vedic collections) date to roughly 15001000 BCE, and the "circum-Vedic" texts, as well as the redaction of the Samhitas, date to c. 1000-500 BCE, resulting in a Vedic period, spanning the mid 2nd to mid 1st millennium BCE, or the Late Bronze Age and the Iron Age. The period between approximately the 6th to 1st centuries BC saw the composition and redaction of the two most influential Indian epics, the Mahabharata and the Ramayana, with subsequent redaction progressing down to the 4th century AD.

Answer:
Sanskrit literature begins with what that dates back to 1300-1100 BCE?
