Input: 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?
Output: an aircraft carrier

Input: Article: The western parts of the Bronx are hillier and are dominated by a series of parallel ridges, running south to north. The West Bronx has older apartment buildings, low income public housing complexes, multifamily homes in its lower income areas as well as larger single family homes in more affluent areas such as Riverdale and Fieldston. It includes New York City's fourth largest park: Van Cortlandt Park along the Westchester-Bronx border. The Grand Concourse, a wide boulevard, runs through it, north to south.

Now answer this question: Where is Van Cortlandt Park?

Output: along the Westchester-Bronx border

Article: Agrobacterium tumefaciens, a soil rhizosphere bacterium, can attach to plant cells and infect them with a callus-inducing Ti plasmid by horizontal gene transfer, causing a callus infection called crown gall disease. Schell and Van Montagu (1977) hypothesised that the Ti plasmid could be a natural vector for introducing the Nif gene responsible for nitrogen fixation in the root nodules of legumes and other plant species. Today, genetic modification of the Ti plasmid is one of the main techniques for introduction of transgenes to plants and the creation of genetically modified crops.

Question: What is this kind of introduction and transfer used for?
Ans: creation of genetically modified crops

Here is a question about this article: On Sentinel Peak (also known as "'A' Mountain"), just west of downtown, there is a giant "A" in honor of the University of Arizona. Starting in about 1916, a yearly tradition developed for freshmen to whitewash the "A", which was visible for miles. However, at the beginning of the Iraq War, anti-war activists painted it black. This was followed by a paint scuffle where the "A" was painted various colors until the city council intervened. It is now red, white and blue except when it is white or another color decided by a biennial election. Because of the three-color paint scheme often used, the shape of the A can be vague and indistinguishable from the rest of the peak. The top of Sentinel Peak, which is accessible by road, offers an outstanding scenic view of the city looking eastward. A parking lot located near the summit of Sentinel Peak was formerly a popular place to watch sunsets or view the city lights at night.
What is the answer to this question: What else is Sentinel Peak also known as?
****
So... 'A' Mountain

According to the official Twenty-Four Histories, the History of Ming compiled in 1739 by the subsequent Qing dynasty (16441912), the Ming dynasty established the "E-Li-Si Army-Civilian Marshal Office" (Chinese: ) in western Tibet and installed the "U-Tsang Itinerant High Commandery" and "Amdo-Kham Itinerant High Commandery" to administer Kham. The Mingshi states that administrative offices were set up under these high commanderies, including one Itinerant Commandery, three Pacification Commissioner's Offices, six Expedition Commissioner's Offices, four Wanhu offices (myriarchies, in command of 10,000 households each) and seventeen Qianhu offices (chiliarchies, each in command of 1,000 households).
What did the Ming dynasty create?
****
The answer: E-Li-Si Army-Civilian Marshal Office

European art music is largely distinguished from many other non-European and popular musical forms by its system of staff notation, in use since about the 16th century. Western staff notation is used by composers to prescribe to the performer the pitches (e.g., melodies, basslines and/or chords), tempo, meter and rhythms for a piece of music. This leaves less room for practices such as improvisation and ad libitum ornamentation, which are frequently heard in non-European art music and in popular music styles such as jazz and blues. Another difference is that whereas most popular styles lend themselves to the song form, classical music has been noted for its development of highly sophisticated forms of instrumental music such as the concerto, symphony, sonata, and mixed vocal and instrumental styles such as opera which, since they are written down, can attain a high level of complexity.
What method is used by composers to prescribe to the performer the pitches, tempo, meter and rhythms for a piece of music?
****
The answer:
Western staff notation
