Problem: Please answer a question about the following article about New Haven, Connecticut:
New Haven is the birthplace of former president George W. Bush, who was born when his father, former president George H. W. Bush, was living in New Haven while a student at Yale. In addition to being the site of the college educations of both Presidents Bush, as Yale students, New Haven was also the temporary home of former presidents William Howard Taft, Gerald Ford, and Bill Clinton, as well as Secretary of State John Kerry. President Clinton met his wife, former U.S. Secretary of State Hillary Rodham Clinton, while the two were students at Yale Law School. Former vice presidents John C. Calhoun and Dick Cheney also studied in New Haven (although the latter did not graduate from Yale). Before the 2008 election, the last time there was not a person with ties to New Haven and Yale on either major party's ticket was 1968. James Hillhouse, a New Haven native, served as President pro tempore of the United States Senate in 1801.
What former U.S. president was born in New Haven?
A: George W. Bush
Problem: Please answer a question about the following article about Incandescent light bulb:
With the help of Charles Stearn, an expert on vacuum pumps, in 1878, Swan developed a method of processing that avoided the early bulb blackening. This received a British Patent in 1880.[dubious discuss] On 18 December 1878, a lamp using a slender carbon rod was shown at a meeting of the Newcastle Chemical Society, and Swan gave a working demonstration at their meeting on 17 January 1879. It was also shown to 700 who attended a meeting of the Literary and Philosophical Society of Newcastle upon Tyne on 3 February 1879. These lamps used a carbon rod from an arc lamp rather than a slender filament. Thus they had low resistance and required very large conductors to supply the necessary current, so they were not commercially practical, although they did furnish a demonstration of the possibilities of incandescent lighting with relatively high vacuum, a carbon conductor, and platinum lead-in wires. Besides requiring too much current for a central station electric system to be practical, they had a very short lifetime. Swan turned his attention to producing a better carbon filament and the means of attaching its ends. He devised a method of treating cotton to produce 'parchmentised thread' and obtained British Patent 4933 in 1880. From this year he began installing light bulbs in homes and landmarks in England. His house was the first in the world to be lit by a lightbulb and also the first house in the world to be lit by hydroelectric power. In 1878 the home of Lord Armstrong at Cragside was also among the first houses to be lit by electricity. In the early 1880s he had started his company. In 1881, the Savoy Theatre in the City of Westminster, London was lit by Swan incandescent lightbulbs, which was the first theatre, and the first public building in the world, to be lit entirely by electricity.
Why was Swan's first lamp not commercially viable?
A:
'parchmentised thread'
