Question: Question: How many years was Taft president? Passage:Howard was born to Ossian Gregory Howard, a lawyer, and Lucy Denham Thurber on 11 June 1857. His relatives from his mother's side included the Harvard astronomer E.C. Pickering while other distant relatives included Senator J.M. Howard and President William Howard Taft.

Along with his friends, he founded the Ithaca Natural History Society to meet and discuss papers and insects. While out collecting one day, he met John Henry Comstock, who invited him to his lab at Cornell University. Howard enrolled in Cornell in September 1873, three years after the death of his father, and following the advice of his mother's friends, went to study civil engineering. Doing poorly in differential calculus made him drop engineering and he began to study other subjects including French, German, and Italian. He then joined Comstock's lab as the first research student and graduated in June 1877 with a thesis on respiration in the larva of Corydalis cornutus. He worked with Burt Green Wilder and Simon Henry Gage and received a masters at Cornell. In the 1880s, he also attended Columbian College (now George Washington University) for medicine, although he didn't complete it. He however received an honorary MD from the same university in 1911 for his contribution to medical entomology.

Question: Question: What's an instrument strongly associated with the traditional music found in the album's sixth track? Passage:It opens with two club-driven tracks: an interlude titled "Bridge to the Sky", and the promotional titular song. "Disco-munication" is the second interlude on the album, blending "sophisticated" electric guitars with electronic music. "Energize" is another electronic track, and is one of the only numbers on the album that include English phases ("Put your hands up together, keep your heads up forever, let me sing forever,"). The fifth track "Sparkle" was noted as a club song with an electronic arrangement, similar to the follow-up song "Rollin'". Both tracks feature autotune and vocoder pro-tools, a first for Hamasaki. The album's sixth track, "Green", shows a departure from the album's earlier electronic style; it focuses more on older traditional Japanese sound, alongside instrumentation of electric guitars and drums. The album's third interlude, "Load of the Shugyo", was described as an "atmospheric" number with heavy rock instruments in its composition. Rock music is then influenced on the following tracks "Identity"a song that discusses about self-confidencethe single "Rule", and the tune "Love 'n' Hate", which talks about the effects of lust. The album's fourth and final interlude "Pieces of Seven" was noted for its "atmospheric" sounds of an ocean, until the second half of the track diverges into a harder rock style. "Days" is the album's first pop ballad, and is described as a love song. It closes with the ballad "Curtain Call", which features a choir and piano riffs throughout its composition.
