Input: Consider Input: Both intensive and free-range farming have animal welfare concerns. In intensive systems, cannibalism, feather pecking and vent pecking can be common, with some farmers using beak trimming as a preventative measure. Diseases can also be common and spread rapidly through the flock. In extensive systems, the birds are exposed to adverse weather conditions and are vulnerable to predators and disease-carrying wild birds. Barn systems have been found to have the worst bird welfare. In Southeast Asia, a lack of disease control in free-range farming has been associated with outbreaks of avian influenza.

Output: What are some of the major concerns with intensive breeding programs?


Input: Consider Input: A loblolly pine, known as the "Eisenhower Pine", was located on Augusta's 17th hole, approximately 210 yards (192 m) from the Masters tee. President Dwight D. Eisenhower, an Augusta National member, hit the tree so many times that, at a 1956 club meeting, he proposed that it be cut down. Not wanting to offend the president, the club's chairman, Clifford Roberts, immediately adjourned the meeting rather than reject the request. The tree was removed in February 2014 after an ice storm caused it significant damage.

Output: At what Augusta hole was the Eisenhower Pine located?


Input: Consider Input: In the 1960s, the first Nanjing Yangtze River Bridge was completed, and served as the only bridge crossing over the Lower Yangtze in eastern China at that time. The bridge was a source of pride and an important symbol of modern China, having been built and designed by the Chinese themselves following failed surveys by other nations and the reliance on and then rejection of Soviet expertise. Begun in 1960 and opened to traffic in 1968, the bridge is a two-tiered road and rail design spanning 4,600 metres on the upper deck, with approximately 1,580 metres spanning the river itself. Since then four more bridges and two tunnels have been built. Going in the downstream direction, the Yangtze crossings in Nanjing are: Dashengguan Bridge, Line 10 Metro Tunnel, Third Bridge, Nanjing Yangtze River Tunnel, First Bridge, Second Bridge and Fourth Bridge.


Output: When was the very first Nanjing Yangtze River Bridge finished?
