Problem: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Iron is usually found as iron ore on Earth, except for one deposit of native iron in Greenland, which was used by the Inuit people. Native copper, however, was found worldwide, along with silver, gold and platinum, which were also used to make tools, jewelry, and other objects since Neolithic times. Copper was the hardest of these metals, and the most widely distributed. It became one of the most important metals to the ancients. Eventually, humans learned to smelt metals such as copper and tin from ore, and, around 2500 BC, began alloying the two metals to form bronze, which is much harder than its ingredients. Tin was rare, however, being found mostly in Great Britain. In the Middle East, people began alloying copper with zinc to form brass. Ancient civilizations took into account the mixture and the various properties it produced, such as hardness, toughness and melting point, under various conditions of temperature and work hardening, developing much of the information contained in modern alloy phase diagrams. Arrowheads from the Chinese Qin dynasty (around 200 BC) were often constructed with a hard bronze-head, but a softer bronze-tang, combining the alloys to prevent both dulling and breaking during use."?

A: Eskimos used iron from where?

Problem: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "After the World Cup, the most important international football competitions are the continental championships, which are organised by each continental confederation and contested between national teams. These are the European Championship (UEFA), the Copa America (CONMEBOL), African Cup of Nations (CAF), the Asian Cup (AFC), the CONCACAF Gold Cup (CONCACAF) and the OFC Nations Cup (OFC). The FIFA Confederations Cup is contested by the winners of all six continental championships, the current FIFA World Cup champions and the country which is hosting the Confederations Cup. This is generally regarded as a warm-up tournament for the upcoming FIFA World Cup and does not carry the same prestige as the World Cup itself. The most prestigious competitions in club football are the respective continental championships, which are generally contested between national champions, for example the UEFA Champions League in Europe and the Copa Libertadores in South America. The winners of each continental competition contest the FIFA Club World Cup."?

A: Who plays in the continental championships?

Problem: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Detroit, like many places in the United States, developed racial conflict and discrimination in the 20th century following rapid demographic changes as hundreds of thousands of new workers were attracted to the industrial city; in a short period it became the 4th-largest city in the nation. The Great Migration brought rural blacks from the South; they were outnumbered by southern whites who also migrated to the city. Immigration brought southern and eastern Europeans of Catholic and Jewish faith; these new groups competed with native-born whites for jobs and housing in the booming city. Detroit was one of the major Midwest cities that was a site for the dramatic urban revival of the Ku Klux Klan beginning in 1915. "By the 1920s the city had become a stronghold of the KKK," whose members opposed Catholic and Jewish immigrants, as well as black Americans. The Black Legion, a secret vigilante group, was active in the Detroit area in the 1930s, when one-third of its estimated 20,000 to 30,000 members in Michigan were based in the city. It was defeated after numerous prosecutions following the kidnapping and murder in 1936 of Charles Poole, a Catholic Works Progress Administration organizer. A total of 49 men of the Black Legion were convicted of numerous crimes, with many sentenced to life in prison for murder."?

A: What was done after the murder of a catholic organizer?

Problem: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Likewise, group theory helps predict the changes in physical properties that occur when a material undergoes a phase transition, for example, from a cubic to a tetrahedral crystalline form. An example is ferroelectric materials, where the change from a paraelectric to a ferroelectric state occurs at the Curie temperature and is related to a change from the high-symmetry paraelectric state to the lower symmetry ferroelectic state, accompanied by a so-called soft phonon mode, a vibrational lattice mode that goes to zero frequency at the transition."?

A:
What is a part of the new state?
