Question: The city has a unique status in Brazil, as it is an administrative division rather than a legal municipality like other cities in Brazil. The name 'Brasilia' is commonly used as a synonym for the Federal District through synecdoche; However, the Federal District is composed of 31 administrative regions, only one of which is Brasilia proper, with a population of 209,926 in a 2011 survey; Demographic publications generally do not make this distinction and list the population of Brasilia as synonymous with the population of the Federal District, considering the whole of it as its metropolitan area. The city was one of the main host cities of the 2014 FIFA World Cup. Additionally, Brasilia hosted the 2013 FIFA Confederations Cup.
Is there an answer to this question: Which Confederations Cup did Brasilia host?

Answer: 2013

Question: When endothermy first appeared in the evolution of mammals is uncertain. Modern monotremes have lower body temperatures and more variable metabolic rates than marsupials and placentals, but there is evidence that some of their ancestors, perhaps including ancestors of the therians, may have had body temperatures like those of modern therians. Some of the evidence found so far suggests that Triassic cynodonts had fairly high metabolic rates, but it is not conclusive. For small animals, an insulative covering like fur is necessary for the maintenance of a high and stable body temperature.
Is there an answer to this question: What do therians need to maintain a stable body temperature?

Answer: unanswerable

Question: Angels in the Outfield was Eisenhower's favorite movie. His favorite reading material for relaxation were the Western novels of Zane Grey. With his excellent memory and ability to focus, Eisenhower was skilled at card games. He learned poker, which he called his "favorite indoor sport," in Abilene. Eisenhower recorded West Point classmates' poker losses for payment after graduation, and later stopped playing because his opponents resented having to pay him. A classmate reported that after learning to play contract bridge at West Point, Eisenhower played the game six nights a week for five months.
Is there an answer to this question: Where did Eisenhower learn to play poker?

Answer: Abilene

Question: During the Permian all the Earth's major land masses, except portions of East Asia, were collected into a single supercontinent known as Pangaea. Pangaea straddled the equator and extended toward the poles, with a corresponding effect on ocean currents in the single great ocean (Panthalassa, the universal sea), and the Paleo-Tethys Ocean, a large ocean that was between Asia and Gondwana. The Cimmeria continent rifted away from Gondwana and drifted north to Laurasia, causing the Paleo-Tethys to shrink. A new ocean was growing on its southern end, the Tethys Ocean, an ocean that would dominate much of the Mesozoic Era. Large continental landmasses create climates with extreme variations of heat and cold ("continental climate") and monsoon conditions with highly seasonal rainfall patterns. Deserts seem to have been widespread on Pangaea.
Is there an answer to this question: What supercontinent prevailed during the Permian era?

Answer:
Pangaea
