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.

[Q]: 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.

[Q]: Question: Which producer who worked on Daylight Crossing is the oldest? Passage:Charley and Hattie collaborated with Jeff Trott (Sheryl Crow, Aimee Mann), Mike Elizondo (Dr. Dre, Fiona Apple), and Steve Booker (Duffy) on material that would become their album Daylight Crossing. Two years later they returned to the UK, where they worked with Universal Records sister company Mercury Records for the album's release. Daylight Crossing was produced by Steve Lipson and Youth, recorded at Sarm Hook End, Abbey Road and Olympic Studios. The album featured musicians Simon Tong and Simon Jones from the band The Verve and Steve Gadd and Pino Palladino. Daylight Crossing was released in June 2006 and became the 'Record of the Week' and 'Album of the Week' at BBC Radio 2, reaching No. 2 on UK's TV music video airplay chart. iTunes chose Daylight Crossing as 'Album of the Week' and singled out the song "Torches" as its 'Single of the Week' during its release week. The Webb Sisters performed on The Sharon Osbourne Show and toured in support of Jamie Cullum (for whom their brother Brad has played drums), Jason Mraz, James Morrison and Kubb, alongside band Leya and Joe Echo. Their song "Still The Only One" was played on the TV show Cane on CBS.

[Q]: Question: What country was azurite mined in during the 12th century? Passage:Azurite is unstable in air, however it was used as a blue pigment in antiquity. Azurite is naturally occurring in Sinai and the Eastern Desert of Egypt. It was reported by F. C. J. Spurrell (1895) in the following examples; a shell used as a pallet in a Fourth Dynasty (2613 to 2494 BCE) context in Meidum, a cloth over the face of a Fifth Dynasty (2494 to 2345 BCE) mummy also at Meidum and a number of Eighteenth Dynasty (15431292 BCE) wall paintings. Depending on the degree of fineness to which it was ground, and its basic content of copper carbonate, it gave a wide range of blues. It has been known as mountain blue or Armenian stone, in addition it was formerly known as Azurro Della Magna (from Italian). When mixed with oil it turns slightly green. When mixed with egg yolk it turns green-grey. It is also known by the names blue bice and blue verditer, though verditer usually refers to a pigment made by chemical process. Older examples of azurite pigment may show a more greenish tint due to weathering into malachite. Much azurite was mislabeled lapis lazuli, a term applied to many blue pigments. As chemical analysis of paintings from the Middle Ages improves, azurite is being recognized as a major source of the blues used by medieval painters. Lapis lazuli (the pigment ultramarine) was chiefly supplied from Afghanistan during the Middle Ages, whereas azurite was a common mineral in Europe at the time. Sizable deposits were found near Lyons, France. It was mined since the 12th century in Saxony, in the silver mines located there.
