Problem: Norfolk Island:

On 8 June 1856, the next settlement began on Norfolk Island. These were the descendants of Tahitians and the HMS Bounty mutineers, including those of Fletcher Christian. They resettled from the Pitcairn Islands, which had become too small for their growing population. On 3 May 1856, 193 persons left Pitcairn Islands aboard the "Morayshire". On 8 June 194 persons arrived, a baby having been born in transit. The Pitcairners occupied many of the buildings remaining from the penal settlements, and gradually established traditional farming and whaling industries on the island. Although some families decided to return to Pitcairn in 1858 and 1863, the island's population continued to grow. They accepted additional settlers, who often arrived with whaling fleets.

Where did the next settlement of people on Norfolk Island settle from?

A: the Pitcairn Islands

Problem: Eton College:

As with other public schools, a scheme was devised towards the end of the 19th century to familiarize privileged schoolboys with social conditions in deprived areas. The project of establishing an 'Eton Mission' in the crowded district of Hackney Wick in east London was started at the beginning of 1880, and lasted until 1971 when it was decided that a more local project (at Dorney) would be more realistic. However over the years much money was raised for the Eton Mission, a fine church by G. F. Bodley was erected, many Etonians visited, and stimulated among other things the Eton Manor Boys' Club, a notable rowing club which has survived the Mission itself, and the 59 Club for motorcyclists.

In what year was the 59 Club started?

Problem: Alloy:

At a certain temperature, (usually between 1,500 F (820 C) and 1,600 F (870 C), depending on carbon content), the base metal of steel undergoes a change in the arrangement of the atoms in its crystal matrix, called allotropy. This allows the small carbon atoms to enter the interstices of the iron crystal, diffusing into the iron matrix. When this happens, the carbon atoms are said to be in solution, or mixed with the iron, forming a single, homogeneous, crystalline phase called austenite. If the steel is cooled slowly, the iron will gradually change into its low temperature allotrope. When this happens the carbon atoms will no longer be soluble with the iron, and will be forced to precipitate out of solution, nucleating into the spaces between the crystals. The steel then becomes heterogeneous, being formed of two phases; the carbon (carbide) phase cementite, and ferrite. This type of heat treatment produces steel that is rather soft and bendable. However, if the steel is cooled quickly the carbon atoms will not have time to precipitate. When rapidly cooled, a diffusionless (martensite) transformation occurs, in which the carbon atoms become trapped in solution. This causes the iron crystals to deform intrinsically when the crystal structure tries to change to its low temperature state, making it very hard and brittle.

What are the characteristics of steel if it is cooled to quickly?
---
A: very hard and brittle

Problem: United States Army:

The United States joined World War II in December 1941 after the Japanese attack on Pearl Harbor. On the European front, U.S. Army troops formed a significant portion of the forces that captured North Africa and Sicily, and later fought in Italy. On D-Day, June 6, 1944, and in the subsequent liberation of Europe and defeat of Nazi Germany, millions of U.S. Army troops played a central role. In the Pacific War, U.S. Army soldiers participated alongside the United States Marine Corps in capturing the Pacific Islands from Japanese control. Following the Axis surrenders in May (Germany) and August (Japan) of 1945, army troops were deployed to Japan and Germany to occupy the two defeated nations. Two years after World War II, the Army Air Forces separated from the army to become the United States Air Force in September 1947 after decades of attempting to separate. Also, in 1948, the army was desegregated by order of President Harry S. Truman.
