Problem: Many of London's pubs are known to have been used by famous people, but in some cases, such as the association between Samuel Johnson and Ye Olde Cheshire Cheese, this is speculative, based on little more than the fact that the person is known to have lived nearby. However, Charles Dickens is known to have visited the Cheshire Cheese, the Prospect of Whitby, Ye Olde Cock Tavern and many others. Samuel Pepys is also associated with the Prospect of Whitby and the Cock Tavern.
Along with the Prospect of Whitby, what pub was Samuel Pepys associated with?
The answer is the following: the Cock Tavern

Problem: 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 is the name of the rule that must be met for a group operation to occur?
The answer is the following: group law

Problem: From the middle of the 3rd century Germanic tribes regularly invaded the Roman territories. Around 275 the Romans could no longer maintain the northern border and Utrecht was abandoned. Little is known about the next period 270650. Utrecht is first spoken of again several centuries after the Romans left. Under the influence of the growing realms of the Franks, during Dagobert I's reign in the 7th century, a church was built within the walls of the Roman fortress. In ongoing border conflicts with the Frisians this first church was destroyed.
What happens between 275 and 650
The answer is the following: Little is known about the next period 270650.

Problem: Tourism is a major industry, estimated in 2001 to support around 23,000 people. Attractions include the coastal towns, part of the Exmoor National Park, the West Somerset Railway (a heritage railway), and the museum of the Fleet Air Arm at RNAS Yeovilton. The town of Glastonbury has mythical associations, including legends of a visit by the young Jesus of Nazareth and Joseph of Arimathea, with links to the Holy Grail, King Arthur, and Camelot, identified by some as Cadbury Castle, an Iron Age hill fort. Glastonbury also gives its name to an annual open-air rock festival held in nearby Pilton. There are show caves open to visitors in the Cheddar Gorge, as well as its locally produced cheese, although there is now only one remaining cheese maker in the village of Cheddar.
Tourism supports how many people in the County
The answer is the following:
estimated in 2001 to support around 23,000 people
