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: When Yesun Temur died in Shangdu in 1328, Tugh Temur was recalled to Khanbaliq by the Qipchaq commander El Temur. He was installed as the emperor (Emperor Wenzong) in Khanbaliq, while Yesun Temur's son Ragibagh succeeded to the throne in Shangdu with the support of Yesun Temur's favorite retainer Dawlat Shah. Gaining support from princes and officers in Northern China and some other parts of the dynasty, Khanbaliq-based Tugh Temur eventually won the civil war against Ragibagh known as the War of the Two Capitals. Afterwards, Tugh Temur abdicated in favour of his brother Kusala, who was backed by Chagatai Khan Eljigidey, and announced Khanbaliq's intent to welcome him. However, Kusala suddenly died only four days after a banquet with Tugh Temur. He was supposedly killed with poison by El Temur, and Tugh Temur then remounted the throne. Tugh Temur also managed to send delegates to the western Mongol khanates such as Golden Horde and Ilkhanate to be accepted as the suzerain of Mongol world. However, he was mainly a puppet of the powerful official El Temur during his latter three-year reign. El Temur purged pro-Kusala officials and brought power to warlords, whose despotic rule clearly marked the decline of the dynasty.

A: How did Yesun Temur die

Q: Passage: The word asphalt is derived from the late Middle English, in turn from French asphalte, based on Late Latin asphalton, asphaltum, which is the latinisation of the Greek (asphaltos, asphalton), a word meaning "asphalt/bitumen/pitch", which perhaps derives from -, "without" and (sfallo), "make fall". Note that in French, the term asphalte is used for naturally occurring bitumen-soaked limestone deposits, and for specialised manufactured products with fewer voids or greater bitumen content than the "asphaltic concrete" used to pave roads. It is a significant fact that the first use of asphalt by the ancients was in the nature of a cement for securing or joining together various objects, and it thus seems likely that the name itself was expressive of this application. Specifically Herodotus mentioned that bitumen was brought to Babylon to build its gigantic fortification wall. From the Greek, the word passed into late Latin, and thence into French (asphalte) and English ("asphaltum" and "asphalt").

A: From where is the word limestone derived?

Q: Passage: However, it is important to understand that despite the presence of reception statutes, much of contemporary American common law has diverged significantly from English common law. The reason is that although the courts of the various Commonwealth nations are often influenced by each other's rulings, American courts rarely follow post-Revolution Commonwealth rulings unless there is no American ruling on point, the facts and law at issue are nearly identical, and the reasoning is strongly persuasive.

A:
Much of American common law is similar to what?
