Problem: Saint Helena:

In 1821, Saul Solomon issued a 70,560 copper tokens worth a halfpenny each Payable at St Helena by Solomon, Dickson and Taylor presumably London partners that circulated alongside the East India Company's local coinage until the Crown took over the island in 1836. The coin remains readily available to collectors.

A: 1836

Problem: Nanjing:

Nanjing is an important railway hub in eastern China. It serves as rail junction for the Beijing-Shanghai (Jinghu) (which is itself composed of the old Jinpu and Huning Railways), NanjingTongling Railway (Ningtong), NanjingQidong (Ningqi), and the Nanjing-Xian (Ningxi) which encompasses the HefeiNanjing Railway. Nanjing is connected to the national high-speed railway network by BeijingShanghai High-Speed Railway and ShanghaiWuhanChengdu Passenger Dedicated Line, with several more high-speed rail lines under construction.

What lines comprise the Beijing-Shanghai (Jinghu) line?
---
A: the old Jinpu and Huning Railways

Problem: Kanye West:

After graduating from high school, West received a scholarship to attend Chicago's American Academy of Art in 1997 and began taking painting classes, but shortly after transferred to Chicago State University to study English. He soon realized that his busy class schedule was detrimental to his musical work, and at 20 he dropped out of college to pursue his musical dreams. This action greatly displeased his mother, who was also a professor at the university. She later commented, "It was drummed into my head that college is the ticket to a good life... but some career goals don't require college. For Kanye to make an album called College Dropout it was more about having the guts to embrace who you are, rather than following the path society has carved out for you."

What subject was Kanye West's focus at Chicago State University?
---
A: English

Problem: Group (mathematics):

Symmetry groups are groups consisting of symmetries of given mathematical objectsbe 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?
