instruction:
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.

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.

question:
Question: Which of the companies involved with the three-dimensional integrated circuit was founded first? Passage:In 1986, Mitsubishi Electric researchers Yoichi Akasaka and Tadashi Nishimura laid out the basic concepts and proposed technologies for 3D ICs. The following year, a Mitsubishi research team including Nishimura, Akasaka and Osaka University graduate Yasuo Inoue fabricated an image signal processor (ISP) on a 3D IC, with an array of photosensors, CMOS A-to-D converters, arithmetic logic units (ALU) and shift registers arranged in a three-layer structure. In 1989, an NEC research team led by Yoshihiro Hayashi fabricated a 3D IC with a four-layer structure using laser beam crystallisation. In 1990, a Matsushita research team including K. Yamazaki, Y. Itoh and A. Wada fabricated a parallel image signal processor on a four-layer 3D IC, with SOI (silicon-on-insulator) layers formed by laser recrystallization, and the four layers consisting of an optical sensor, level detector, memory and ALU.

question:
Question: How much water does the object hold that is located at the north side of the nave? Passage:The roof of the nave is painted red and is divided into squares by ribs, at whose intersections are gilded bosses of different designs. The font is located halfway down the north side of the nave. It is Victorian and consists of an octagonal gabled and crocketted bowl on an octagonal column. The wooden pulpit is massive, measuring approximately from the base to the top. To the east of the south door are churchwardens' box pews carved with Gothic details and poppyheads. They bear a brass plate dated 1770. In the nave are monuments to the memory of the Cliftons of Lytham Hall, including one to Thomas Clifton who died in 1688. A wall tablet commemorates Richard Bradkirk of Bryning Hall who died in 1813 and another monument is to Henry Rishton Buck, a lieutenant aged 27 who died at the Battle of Waterloo. Behind the altar is a folding reredos dated 1900 which was made by Kempe and moved from Christ Church Cathedral, Oxford. The brass chandelier dated 1725 was made by Brown of Wigan. The organ dates back to 1769 when it was built by Glyn Parker of Salford. Later modifications were made by R. W. Nicholson of Bradford (at an unrecorded date), by Harrison & Harrison in 1905, and by the Pendlebury Organ Company of Cleveleys in 1979. There is a ring of eight bells which were cast by Charles & George Mears at the Whitechapel Bell Foundry in 1846.
