Problem: Melbourne:

With the wealth brought on by the gold rush following closely on the heels of the establishment of Victoria as a separate colony and the subsequent need for public buildings, a program of grand civic construction soon began. The 1850s and 1860s saw the commencement of Parliament House, the Treasury Building, the Old Melbourne Gaol, Victoria Barracks, the State Library, University, General Post Office, Customs House, the Melbourne Town Hall, St Patrick's cathedral, though many remained uncompleted for decades, with some still not finished.

During what two decades were the Parliament House, Treasury Building, Victoria Barracks, State Library, and General Post Office commenced?

A: 1850s and 1860s


Problem: Steven Spielberg:

Spielberg directed 2015's Bridge of Spies, a Cold War thriller based on the 1960 U-2 incident, and focusing on James B. Donovan's negotiations with the Soviets for the release of pilot Gary Powers after his aircraft was shot down over Soviet territory. The film starred Tom Hanks as Donovan, as well as Mark Rylance, Amy Ryan, and Alan Alda, with a script by the Coen brothers. The film was shot from September to December 2014 on location in New York City, Berlin and Wroclaw, Poland (which doubled for East Berlin), and was released by Disney on October 16, 2015. Bridge of Spies received positive reviews from critics, and was nominated for six Academy Awards, including Best Picture.

Where was most of Bridge of Spies shot?

Problem: Muammar Gaddafi:

With crude oil as the country's primary export, Gaddafi sought to improve Libya's oil sector. In October 1969, he proclaimed the current trade terms unfair, benefiting foreign corporations more than the Libyan state, and by threatening to reduce production, in December Jalloud successfully increased the price of Libyan oil. In 1970, other OPEC states followed suit, leading to a global increase in the price of crude oil. The RCC followed with the Tripoli Agreement, in which they secured income tax, back-payments and better pricing from the oil corporations; these measures brought Libya an estimated $1 billion in additional revenues in its first year.

How did Gaddafi's decisions in the oil industry impact other OPEC states?

A: In 1970, other OPEC states followed suit, leading to a global increase in the price of crude oil.


Problem: Group (mathematics):

Symmetry groups are groups consisting of symmetries of given mathematical objects—be they of geometric nature, such as the introductory symmetry group of the square, or of algebraic nature, such as polynomial equations and their solutions. Conceptually, group theory can be thought of as the study of symmetry.t[›] Symmetries in mathematics greatly simplify the study of geometrical or analytical objects. A group is said to act on another mathematical object X if every group element performs some operation on X compatibly to the group law. In the rightmost example below, an element of order 7 of the (2,3,7) triangle group acts on the tiling by permuting the highlighted warped triangles (and the other ones, too). By a group action, the group pattern is connected to the structure of the object being acted on.

What does group action do to the tiling?
