Problem: Please answer a question about the following article about Canadian Armed Forces:
Since 1947, Canadian military units have participated in more than 200 operations worldwide, and completed 72 international operations. Canadian soldiers, sailors, and aviators came to be considered world-class professionals through conspicuous service during these conflicts and the country's integral participation in NATO during the Cold War, First Gulf War, Kosovo War, and in United Nations Peacekeeping operations, such as the Suez Crisis, Golan Heights, Cyprus, Croatia, Bosnia, Afghanistan, and Libya. Canada maintained an aircraft carrier from 1957 to 1970 during the Cold War, which never saw combat but participated in patrols during the Cuban Missile Crisis.
What type of military vehicle was maintained almost 15 years but never saw any action during the Cuban crisis?
A: an aircraft carrier
Problem: Please answer a question about the following article about Antenna (radio):
Rather than just using a thick tube, there are similar techniques used to the same effect such as replacing thin wire elements with cages to simulate a thicker element. This widens the bandwidth of the resonance. On the other hand, amateur radio antennas need to operate over several bands which are widely separated from each other. This can often be accomplished simply by connecting resonant elements for the different bands in parallel. Most of the transmitter's power will flow into the resonant element while the others present a high (reactive) impedance and draw little current from the same voltage. A popular solution uses so-called traps consisting of parallel resonant circuits which are strategically placed in breaks along each antenna element. When used at one particular frequency band the trap presents a very high impedance (parallel resonance) effectively truncating the element at that length, making it a proper resonant antenna. At a lower frequency the trap allows the full length of the element to be employed, albeit with a shifted resonant frequency due to the inclusion of the trap's net reactance at that lower frequency.
How could one achieve the task of creating an antenna that can be Used over various bands?
A: connecting resonant elements
Problem: Please answer a question about the following article about Westminster Abbey:
Henry III rebuilt the abbey in honour of a royal saint, Edward the Confessor, whose relics were placed in a shrine in the sanctuary. Henry III himself was interred nearby, as were many of the Plantagenet kings of England, their wives and other relatives. Until the death of George II of Great Britain in 1760, most kings and queens were buried in the abbey, some notable exceptions being Henry VI, Edward IV, Henry VIII and Charles I who are buried in St George's Chapel at Windsor Castle. Other exceptions include Richard III, now buried at Leicester Cathedral, and the de facto queen Lady Jane Grey, buried in the chapel of St Peter ad Vincula in the Tower of London. Most monarchs and royals who died after 1760 are buried either in St George's Chapel or at Frogmore to the east of Windsor Castle.[citation needed]
Who was Edward the Confessor?
A: a royal saint
Problem: Please answer a question about the following article about England national football team:
England failed to qualify for the World Cup in 1974, 1978 and 1994. The team's earliest exit in the competition itself was its elimination in the first round in 1950, 1958 and most recently in the 2014 FIFA World Cup, after being defeated in both their opening two matches for the first time, versus Italy and Uruguay in Group D. In 1950, four teams remained after the first round, in 1958 eight teams remained and in 2014 sixteen teams remained. In 2010, England suffered its most resounding World Cup defeat (41 to Germany) in the Round of 16, after drawing with the United States and Algeria and defeating Slovenia 10 in the group stage.
In 2014, England was eliminated from the World Cup after being defeated by Italy and which other team?
A:
Uruguay
