Sampson had just become eligible to be a college coach again after receiving a five-year show cause penalty in 2008 for sanctions against him during his time as Indiana head coach. In 2014–15, Houston struggled again, finishing with a 13–19 record and 4–14 in the AAC. The 2015–16 team led a resurgence, finishing 22–10, 12–6, but lost in the AAC Tournament and in the first round of the NIT. In 2017–18, the Cougars compiled a 27–8 record, reaching the finals of the AAC Tournament and winning a game in the NCAA Tournament for the first time since 1984.

Q: Passage: In modern times, the creation of relatively simple dome-like structures has been documented among various indigenous peoples around the world. The wigwam was made by Native Americans using arched branches or poles covered with grass or hides. The Efé people of central Africa construct similar structures, using leaves as shingles. Another example is the igloo, a shelter built from blocks of compact snow and used by the Inuit people, among others. The Himba people of Namibia construct "desert igloos" of wattle and daub for use as temporary shelters at seasonal cattle camps, and as permanent homes by the poor. Extraordinarily thin domes of sun-baked clay 20 feet in diameter, 30 feet high, and nearly parabolic in curve, are known from Cameroon.
