Problem: Since the introduction of league football, most club sides play a number of friendlies before the start of each season (called pre-season friendlies). Friendly football matches are considered to be non-competitive and are only used to "warm up" players for a new season/competitive match. There is generally nothing competitive at stake and some rules may be changed or experimented with (such as unlimited substitutions, which allow teams to play younger, less experienced, players, and no cards). Although most friendlies are simply one-off matches arranged by the clubs themselves, in which a certain amount is paid by the challenger club to the incumbent club, some teams do compete in short tournaments, such as the Emirates Cup, Teresa Herrera Trophy and the Amsterdam Tournament. Although these events may involve sponsorship deals and the awarding of a trophy and may even be broadcast on television, there is little prestige attached to them.
When do football clubs still play friendlies?
The answer is the following: before the start of each season

Problem: The decline in the value of the U.S. dollar corresponds to price inflation, which is a rise in the general level of prices of goods and services in an economy over a period of time. A consumer price index (CPI) is a measure estimating the average price of consumer goods and services purchased by households. The United States Consumer Price Index, published by the Bureau of Labor Statistics, is a measure estimating the average price of consumer goods and services in the United States. It reflects inflation as experienced by consumers in their day-to-day living expenses. A graph showing the U.S. CPI relative to 19821984 and the annual year-over-year change in CPI is shown at right.
What does the CPI estimate?
The answer is the following: average price of consumer goods and services in the United States

Problem: In 121 BC, Rome came into contact with two Celtic tribes (from a region in modern France), both of which they defeated with apparent ease. The Cimbrian War (113101 BC) was a far more serious affair than the earlier clashes of 121 BC. The Germanic tribes of the Cimbri and the Teutons migrated from northern Europe into Rome's northern territories, and clashed with Rome and her allies. At the Battle of Aquae Sextiae and the Battle of Vercellae both tribes were virtually annihilated, which ended the threat.
What war began in the year 113 BC?
The answer is the following: The Cimbrian War

Problem: Pope Paul VI became the first reigning pontiff ever to visit the Americas when he flew to New York in October 1965 to address the United Nations. As a gesture of goodwill, the pope gave to the UN two pieces of papal jewelry, a diamond cross and ring, with the hopes that the proceeds from their sale at auction would contribute to the UN's efforts to end human suffering. During the pope's visit, as the U.S. involvement in the Vietnam War escalated under President Johnson, Paul VI pleaded for peace before the UN:
What group did Paul VI address in New York in 1965?
