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.

Example Input: Question: Of the musical acts Vixen toured with, which one has been active the longest? Passage:Born in St. Paul, Minnesota, Kuehnemund formed an all-female band known as Genesis in St. Paul in 1971, initially as a quintet under the name Lemon Pepper. Her father Carl served as a roadie during her band's earliest days. Genesis was later renamed Vixen to prevent confusion with the same-named English band before breaking up in 1974. A bandmate of hers during that year was Nancy Shanks. After a six-year hiatus she reformed Vixen and shortly moved her band to Los Angeles in 1981, and, in 1983, singer Janet Gardner joined her. The band gained notice by appearing in the 1984 teen film Hardbodies under the on-screen name Diaper Rash. They were also a quintet at the time. She eventually added Roxy Petrucci on drums and fellow Minnesotan Share Ross, then known as Share Pedersen, on bass, the lineup that signed to EMI Records. They released their self-titled debut, Vixen, in 1988. It was released by Manhattan Records in the U.S. and Canada. The band toured with the Scorpions, Ozzy Osbourne, and Bon Jovi, and appeared in Penelope Spheeris' 1988 film, , although only Gardner, Pedersen, and Petrucci appeared in the film.

Example 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.

Example Input: Question: Where was Billboard Frolics' creator born? Passage:Cantor appears in caricature form in numerous Looney Tunes cartoons produced for Warner Bros., although he was often voiced by an imitator. Beginning with I Like Mountain Music (1933), other animated Cantor cameos include Shuffle Off to Buffalo (Harman-Ising, 1933) and Billboard Frolics (Friz Freleng, 1935). Eddie Cantor is one of the four "down on their luck" stars (along with Bing Crosby, Al Jolson, and Jack Benny) snubbed by Elmer Fudd in What’s Up, Doc? (Bob McKimson, 1950). In Farm Frolics (Bob Clampett, 1941), a horse, asked by the narrator to "do a canter", promptly launches into a singing, dancing, eye-rolling impression. The Cantor gag that got the most mileage, however, was his oft-repeated wish for a son after five famous daughters. Slap-Happy Pappy (Clampett, 1940) features an "Eddie Cackler" rooster that wants a boy, to little avail. Other references can be found in Baby Bottleneck (Clampett, 1946) and Circus Today (Tex Avery, 1940). In Merrie Melodies, The Coo-Coo Nut Grove Cantor's many daughters are referenced by a group of singing quintuplet girls. In Porky’s Naughty Nephew (Clampett, 1938) a swimming Cantor gleefully adopts a "buoy". An animated Cantor also appears prominently in Walt Disney's "Mother Goose Goes Hollywood" (Wilfred Jackson, 1938) as Little Jack Horner, who sings "Sing a Song of Sixpence".
