Problem: United States dollar:

In 1862, paper money was issued without the backing of precious metals, due to the Civil War. Silver and gold coins continued to be issued and in 1878 the link between paper money and coins was reinstated. This disconnection from gold and silver backing also occurred during the War of 1812. The use of paper money not backed by precious metals had also occurred under the Articles of Confederation from 1777 to 1788. With no solid backing and being easily counterfeited, the continentals quickly lost their value, giving rise to the phrase "not worth a continental". This was a primary reason for the "No state shall... make any thing but gold and silver coin a tender in payment of debts" clause in article 1, section 10 of the United States Constitution.

The quick loss in value of paper money resulted in which phrase being hear?

A: "not worth a continental"


Problem: Sport plays an important role in Estonian culture. After declaring independence from Russia in 1918, Estonia first competed as a nation at the 1920 Summer Olympics, although the National Olympic Committee was established in 1923. Estonian athletes took part of the Olympic Games until the country was annexed by the Soviet Union in 1940. The 1980 Summer Olympics Sailing regatta was held in the capital city Tallinn. After regaining independence in 1991, Estonia has participated in all Olympics. Estonia has won most of its medals in athletics, weightlifting, wrestling and cross-country skiing. Estonia has had very good success at the Olympic games given the country's small population. Estonia's best results were being ranked 13th in the medal table at the 1936 Summer Olympics, and 12th at the 2006 Winter Olympics.
What city hosted the 1980 Summer Olympics Sailing regatta?

Answer: Tallinn

Following the 1914–15 edition, the competition was suspended due to the First World War, and didn't resume until 1919–20. The 1922–23 competition saw the first final to be played in the newly opened Wembley Stadium (known at the time as the Empire Stadium). Due to the outbreak of World War II, the competition wasn't played between the 1938–39 and 1945–46 editions. Due to the wartime breaks, the competition didn't celebrate its centenary year until 1980–81; fittingly the final featured a goal by Ricky Villa which was later voted the greatest goal ever scored at Wembley Stadium, but has since been replaced by Steven Gerrard.
When did Wembly stadium open? 
A: 1922–23

Question: Most CBC television stations, including those in the major cities, are owned and operated by the CBC itself. CBC O&O stations operate as a mostly seamless national service with few deviations from the main network schedule, although there are some regional differences from time to time. For on-air identification, most CBC stations use the CBC brand rather than their call letters, not identifying themselves specifically until sign-on or sign-off (though some, like Toronto's CBLT, do not ID themselves at all except through PSIP). All CBC O&O stations have a standard call letter naming convention, in that the first two letters are "CB" (an ITU prefix allocated not to Canada, but to Chile) and the last letter is "T". Only the third letter varies from market to market; however, that letter is typically the same as the third letter of the CBC Radio One and CBC Radio 2 stations in the same market. An exception to this rule are the CBC North stations in Yellowknife, Whitehorse and Iqaluit, whose call signs begin with "CF" due to their historic association with the CBC's Frontier Coverage Package prior to the advent of microwave and satellite broadcasting.
Is there an answer to this question: What station does not identify itself by its call letters?

Answer: Toronto's CBLT
