Problem: Charleston, South Carolina:

On June 17, 2015, 21-year-old Dylann Roof entered the historic Emanuel African Methodist Episcopal Church during a Bible study and killed nine people. Senior pastor Clementa Pinckney, who also served as a state senator, was among those killed during the attack. The deceased also included congregation members Susie Jackson, 87; Rev. Daniel Simmons Sr., 74; Ethel Lance, 70; Myra Thompson, 59; Cynthia Hurd, 54; Rev. Depayne Middleton-Doctor, 49; Rev. Sharonda Coleman-Singleton, 45; and Tywanza Sanders, 26. The attack garnered national attention, and sparked a debate on historical racism, Confederate symbolism in Southern states, and gun violence. On July 10, 2015, the Confederate battle flag was removed from the South Carolina State House. A memorial service on the campus of the College of Charleston was attended by President Barack Obama, Michelle Obama, Vice President Joe Biden, Jill Biden, and Speaker of the House John Boehner.

Problem: The Alpine orogeny occurred in ongoing cycles through to the Paleogene causing differences in nappe structures, with a late-stage orogeny causing the development of the Jura Mountains. A series of tectonic events in the Triassic, Jurassic and Cretaceous periods caused different paleogeographic regions. The Alps are subdivided by different lithology (rock composition) and nappe structure according to the orogenic events that affected them. The geological subdivision differentiates the Western, Eastern Alps and Southern Alps: the Helveticum in the north, the Penninicum and Austroalpine system in the center and, south of the Periadriatic Seam, the Southern Alpine system.
What is another word for rock composition?

Answer: lithology

During Soviet rule, Armenian athletes rose to prominence winning plenty of medals and helping the USSR win the medal standings at the Olympics on numerous occasions. The first medal won by an Armenian in modern Olympic history was by Hrant Shahinyan, who won two golds and two silvers in gymnastics at the 1952 Summer Olympics in Helsinki. In football, their most successful team was Yerevan's FC Ararat, which had claimed most of the Soviet championships in the 70s and had also gone to post victories against professional clubs like FC Bayern Munich in the Euro cup.
When did FC Bayern Munich first win olympic medals?
A: unanswerable


Context and question: The mayor of Paris is elected indirectly by Paris voters; the voters of each arrondissement elect the Conseil de Paris (Council of Paris), composed of 163 members. Each arrondissement has a number of members depending upon its population, from 10 members for each of the least-populated arrondissements (1st through 9th) to 36 members for the most populated (the 15th). The elected council members select the mayor. Sometimes the candidate who receives the most votes city-wide is not selected if the other candidate has won the support of the majority of council members. Mayor Bertrand Delanoë (2001-2014) was elected by only a minority of city voters, but a majority of council members. Once elected, the council plays a largely passive role in the city government; it meets only once a month. The current council is divided between a coalition of the left of 91 members, including the socialists, communists, greens, and extreme left; and 71 members for the centre right, plus a few members from smaller parties.
What years was Bertrand Delanoe Mayor?
Answer: 2001-2014


Question: With its myriad islands, Alaska has nearly 34,000 miles (54,720 km) of tidal shoreline. The Aleutian Islands chain extends west from the southern tip of the Alaska Peninsula. Many active volcanoes are found in the Aleutians and in coastal regions. Unimak Island, for example, is home to Mount Shishaldin, which is an occasionally smoldering volcano that rises to 10,000 feet (3,048 m) above the North Pacific. It is the most perfect volcanic cone on Earth, even more symmetrical than Japan's Mount Fuji. The chain of volcanoes extends to Mount Spurr, west of Anchorage on the mainland. Geologists have identified Alaska as part of Wrangellia, a large region consisting of multiple states and Canadian provinces in the Pacific Northwest, which is actively undergoing continent building.
Is there an answer to this question: How high does Mount Shishaldin rise above sea level?

Answer: 10,000 feet (3,048 m)


Problem: Adolescence:

A third gain in cognitive ability involves thinking about thinking itself, a process referred to as metacognition. It often involves monitoring one's own cognitive activity during the thinking process. Adolescents' improvements in knowledge of their own thinking patterns lead to better self-control and more effective studying. It is also relevant in social cognition, resulting in increased introspection, self-consciousness, and intellectualization (in the sense of thought about one's own thoughts, rather than the Freudian definition as a defense mechanism). Adolescents are much better able than children to understand that people do not have complete control over their mental activity. Being able to introspect may lead to two forms of adolescent egocentrism, which results in two distinct problems in thinking: the imaginary audience and the personal fable. These likely peak at age fifteen, along with self-consciousness in general.

The imaginary audience and personal fable peak at what age?

A:
fifteen
