[EX 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.
[EX A]: How did Yesun Temur die

[EX Q]: Passage: Northwestern fielded its first intercollegiate football team in 1882, later becoming a founding member of the Big Ten Conference. In the 1870s and 1880s, Northwestern affiliated itself with already existing schools of law, medicine, and dentistry in Chicago. The Northwestern University School of Law is the oldest law school in Chicago. As the university increased in wealth and distinction, and enrollments grew, these professional schools were integrated with the undergraduate college in Evanston; the result was a modern research university combining professional, graduate, and undergraduate programs, which gave equal weight to teaching and research. The Association of American Universities invited Northwestern to become a member in 1917.
[EX A]: What sports team did Northwestern field its first of in 1982?

[EX Q]: Passage: All federal agencies are prohibited from authorizing, funding or carrying out actions that "destroy or adversely modify" critical habitats (Section 7(a) (2)). While the regulatory aspect of critical habitat does not apply directly to private and other non-federal landowners, large-scale development, logging and mining projects on private and state land typically require a federal permit and thus become subject to critical habitat regulations. Outside or in parallel with regulatory processes, critical habitats also focus and encourage voluntary actions such as land purchases, grant making, restoration, and establishment of reserves.
[EX A]:
What are federal agencies allowed to do to critical habitats?
