Problem: 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.
Which time period is suggested that cynodonts had a high metabolic rate?

Answer: Triassic


Problem: In Lebanon, clashes between pro-Nasser factions and supporters of staunch Nasser opponent, then-President Camille Chamoun, culminated in civil strife by May. The former sought to unite with the UAR, while the latter sought Lebanon's continued independence. Nasser delegated oversight of the issue to Sarraj, who provided limited aid to Nasser's Lebanese supporters through money, light arms, and officer training—short of the large-scale support that Chamoun alleged. Nasser did not covet Lebanon, seeing it as a "special case", but sought to prevent Chamoun from a second presidential term.
What did Lebanese pro-Nasser groups want?
---
Answer: to unite with the UAR


Problem: Napoleon could be considered one of the founders of modern Germany. After dissolving the Holy Roman Empire, he reduced the number of German states from 300 to less than 50, paving the way to German Unification. A byproduct of the French occupation was a strong development in German nationalism. Napoleon also significantly aided the United States when he agreed to sell the territory of Louisiana for 15 million dollars during the presidency of Thomas Jefferson. That territory almost doubled the size of the United States, adding the equivalent of 13 states to the Union.
How many German states remained after Napoleon reduced their numbers?
---
Answer:
less than 50
