Mixed martial arts (MMA), or cage fighting, is a combat sport incorporating various fighting techniques. Professional bouts began in the US in the 1990s and were in the style of vale tudo—"anything goes" in Portuguese—but as MMA gained more mainstream popularity, some safety rules were adopted. Though it is often seen as brutal, MMA may actually be safer than boxing because it results in fewer knockouts. How many deaths have been attributed to injuries sustained in sanctioned MMA events?

World War II left the finances and industry of Europe crippled. In 1947, Marshall proposed a plan for the US to finance the European recovery. From 1948 to 1952, it provided almost $13 billion in grants and loans to 17 countries and was a key factor in reviving their economies and stabilizing their political structures. While most of Europe embraced the plan, it was strongly opposed by the Soviet Union and some Eastern European nations. How, according to Marshall, would this plan benefit the US?

Before the planet Neptune was discovered, Adams—an English astronomer and mathematician—correctly predicted its existence and position based on irregularities in the motion of Uranus. However, the credit for the discovery went to Urbain Leverrier, who had come to the same conclusion later but published his findings earlier. In 1846, the planet was first observed by a German astronomer using Leverrier's calculations. A modest man, Adams also declined to publish what other findings?
