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: What is the singer that Hank mocks most famous song? Passage:Publicist Jolene (Denise Richards) has a tense relationship with rock musician Hank (James Stevenson), who is planning to marry journalist Rose (Lauren German). As the lead singer of the band Modern Apes, Hank performs "mocking [and] self-congratulatory" versions of Barry Manilow's music. According to Tatiana Morales of CBS News, people compared Jolene to Amanda Woodward from Melrose Place. Muir characterized Jolene as a maneater, and Phil Gallo of Variety viewed her as "a devilish character with a dark soul". On the other hand, Shandy Casteel of PopMatters described Rose as the girl next door. David Bianculli of the New York Daily News cited her as the show's lead character. In the pilot episode, Rose receives the ashes of her ex-boyfriend Billy (Dylan Bruno), but it is revealed he is alive when he re-enters the characters' lives. Jolene believes that Rose had ruined her relationship with Billy, and responds by plotting to take Hank as "a means to nasty retaliation". As part of the show's comedy, Rose imagines people singing pop music to her.

Example Input: Question: What is the faculty size of the school where adjunct professor of playwriting, acting and directing in the Department of Theatre and Dance? Passage:Harold Athol Lanigan Fugard OIS (born 11 June 1932) is a South African playwright, novelist, actor, and director who writes in South African English. He is best known for his political plays opposing the system of apartheid and for the 2005 Academy Award-winning film of his novel Tsotsi, directed by Gavin Hood. Fugard was an adjunct professor of playwriting, acting and directing in the Department of Theatre and Dance at the University of California, San Diego. For the academic year 20002001, he was the IU Class of 1963 Wells Scholar Professor at Indiana University, in Bloomington, Indiana. He is the recipient of many awards, honours, and honorary degrees, including the 2005 Order of Ikhamanga in Silver "for his excellent contribution and achievements in the theatre" from the government of South Africa. He is also an Honorary Fellow of the Royal Society of Literature.

Example Input: Question: When was the technology used at Mount Wilson, Mount Locke, and Mauna Kea invented? Passage:In the 1970s, astronomers saw some major advances in astronomical imaging technology, beginning with Antoine Labeyrie's invention of speckle interferometry, a process that significantly reduced the blurring effect caused by astronomical seeing. It increased the optical resolution of ground-based telescopes, allowing for more precise measurements of Betelgeuse's photosphere. With improvements in infrared telescopy atop Mount Wilson, Mount Locke and Mauna Kea in Hawaii, astrophysicists began peering into the complex circumstellar shells surrounding the supergiant, causing them to suspect the presence of huge gas bubbles resulting from convection. But it was not until the late 1980s and early 1990s, when Betelgeuse became a regular target for aperture masking interferometry, that breakthroughs occurred in visible-light and infrared imaging. Pioneered by John E. Baldwin and colleagues of the Cavendish Astrophysics Group, the new technique employed a small mask with several holes in the telescope pupil plane, converting the aperture into an ad-hoc interferometric array. The technique contributed some of the most accurate measurements of Betelgeuse while revealing bright spots on the star's photosphere. These were the first optical and infrared images of a stellar disk other than the Sun, taken first from ground-based interferometers and later from higher-resolution observations of the COAST telescope. The "bright patches" or "hotspots" observed with these instruments appeared to corroborate a theory put forth by Schwarzschild decades earlier of massive convection cells dominating the stellar surface.
