[EX Q]: 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. Shortly after his birth, the family moved from Rockford, to Ithaca, New York where his father worked with a law firm. Howard attended Ithaca Academy. An interest in insect collecting encouraged by his parents with the gift of The Butterfly Hunters by Mary Treat at the age of 10 followed by more books and at the age of 13, along with another collector friend, recorded the introduction of the European cabbage butterfly (Pieris rapae) in the Catskill region. 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.

[EX Q]: Question: What was the former name of the Blohmn & Voss aircraft division? Passage:Soon after the start of World War II, it was proposed to convert the four prototypes to long-range maritime patrol aircraft. V2 underwent a trial modification. It was fitted with an extended nose section with extensive glazing (like the Heinkel He 111 H-6), defensive armament (a 7.92mm/.312in MG 15 machine gun in the nose, twin-beam positions, a ventral cupola, and a powered dorsal turret), a compartment for ordnance in the fuselage, and navigation and military radio equipment. The company had by now been renamed as the Blohm & Voss aircraft division so the converted aircraft was redesignated the BV 142 V2/U1 while the V1 was similarly converted. Both were used operationally from late 1940 and were posted to the Luftwaffes second surveillance Group. This unit was assigned to the operations staff of Luftflotte III in France. However, their performance was disappointing, and after only a few missions they were withdrawn from service in 1942. Aircraft V3 and V4 were used as transport aircraft for the occupation of Denmark and in the Norway campaign with the KGr.z.b.V. 105 (Special combat team) and could transport 30 fully equipped soldiers over 4,000km (2,490mi). The ultimate fate of V3 and V4 is unknown. It was later planned to use the V1 and V2 to carry the Henschel GT 1200C guided torpedo, but the plan was cancelled.
