In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Input: Consider Input: Question: When did the expedition that John Colter was apart of in 1807 begin? Passage:Europeans may have ventured into the northern sections of the state in the late 18th century. Most of the southern part of modern-day Wyoming was nominally claimed by Spain and Mexico until the 1830s, but they had no presence. John Colter, a member of the Lewis and Clark Expedition, was probably the first American to enter the region in 1807. His reports of thermal activity in the Yellowstone area were considered at the time to be fictional. Robert Stuart and a party of five men returning from Astoria, Oregon discovered South Pass in 1812. The route was later followed by the Oregon Trail. In 1850, Jim Bridger located what is now known as Bridger Pass, which was later used by both the Union Pacific Railroad in 1868, and in the 20th century by Interstate 80. Bridger also explored the Yellowstone region and like Colter, most of his reports on that region of the state were considered at the time to be tall tales. During the early 19th century, fur trappers known as mountain men flocked to the mountains of western Wyoming in search of beaver. In 1824, the first mountain man rendezvous was held in Wyoming. The gatherings continued annually until 1840, with the majority of them held within Wyoming territory.

Input: Consider Input: Question: What state did Sayre attend college? Passage:Anne Sayre was "born on a train passing through Milwaukee". She spent her childhood in Woodmere, New York, and was educated at Radcliffe College. But the Second World War prevented her to pursue law, her main ambition. To render her service in the war, she worked in the Radiation Laboratory at Massachusetts Institute of Technology. Her job there was managing the supply of special-design transformers. She never really knew what transformers were. She took the job for only a few months, but she met her future husband, David Sayre. (David Sayre was a physics student who also volunteered for war service during his academic break.) They got married in 1947. Married to a scientist, she described herself as "a camp-follower to the scientists". She soon took up writing career, mainly of short stories, of which many were included in the Foley's and the Best American Short Stories collections. In 1949, they moved to England as David Sayre was enrolled for PhD at the University of Oxford to work under Dorothy Hodgkin (a 1964 Nobel laureate). Anne Sayre financially supported most of their financial expenses through her writings. She eventually got appointed as an editor at the Oxford University Press. David received his PhD in 1951, and in September they returned to US. In 1975, Anne revived her ambition to become a lawyer and got enrolled in New York University Law School, from where she graduated with high grades. She devoted her service in legal matters, particularly concerning environment, in Long Island. She initially served as volunteer Legal Aid lawyer in Riverhead. Later, she was appointed justice in the Head of the Harbor, a post she held until illness prompted her to resign in 1996. Since the late 1980s she had suffered from pneumonia and the complications of scleroderma, a rare form of rheumatism. She died on March 13, 1998 in a hospital near her home in Bridgewater Township, New Jersey, and was survived by her husband.

Input: Consider Input: Question: How old was Emperor Meiji of Japan when he received Ernesto Burzagli following the end of the war? Passage:Burzagli was from a noble family of Montevarchi, but was born in Modena, as his father had relocated there to assume a position as a professor of physics at the Military Academy of Modena. Burzagli graduated from the Accademia Navale di Livorno in 1892, and after serving on a number of ships in the Royal Italian Navy, he was assigned as a military attaché to Tokyo, Japan in May 1904. He arrived just in time to become an official foreign observer of the Imperial Japanese Navy in the Russo-Japanese War, and witnessed first-hand the naval bombardment of Port Arthur. After the end of the war, in April 1906, he was received by Emperor Meiji of Japan, and received the Order of the Rising Sun before his return to Italy.
