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 population of the city where the East Jordan Canal is heading? Passage:State Street continues north through the Crescent neighborhood, past the site of the historic Crescent Elementary School, and enters Downtown Sandy. It intersects 10600 South, which becomes State Route 151 a short distance to the west, and passes a large retail area that includes big box stores and the South Towne Mall. The street climbs a small hill to pass over the Jordan and Salt Lake Canal, then passes a cemetery and a small amount of undeveloped greenfield land near the crossing of Dry Creek before reaching a larger hill into which the East Jordan Canal is carved. At the top of this hill, the street passes west of Jordan High School and the South Towne Expo Center before intersecting 9400 South (former State Route 209). A short distance north of that intersection, the East Jordan Canal passes back under the street on its way toward Holladay, and Rio Tinto Stadium fronts onto the street on the west side. Just before the intersection with 9000 South (modern State Route 209), State Street passes the site of a former smelter (which now has a medical center built on part of it). The street forms the western boundary of the Sandy Historic District from 9000 South to Pioneer Avenue (8530 South), and several historic buildings face onto it in this area. There is a traffic signal it the intersection with Sandy's Main Street at 8720 South. North of the historic district, State Street passes through some relatively lightly developed land near the city's border with Midvale, though there are some townhouse developments in progress in the area.

Example Input: Question: Which of Shapovalov's opponents at Gatineau and Drummondville was younger? Passage:In March in Gatineau, Shapovalov captured his fourth ITF Futures singles title after defeating Gleb Sakharov in straight sets. Two weeks later, he won his first ATP Challenger title with a victory over Ruben Bemelmans at the 75K in Drummondville, and was the youngest Canadian to win a Challenger until Felix Auger-Aliassime's victory at the Open Sopra Steria de Lyon later in the year. The next week, he was defeated by Mirza Basic in the final of the ATP Challenger 50K in Guadalajara, stopping his winning streak at 17 matches. At the French Open in May, his first professional Grand Slam, he was defeated in the first round of qualifying by the first seed Marius Copil in three sets. In June, Shapovalov qualified for the ATP 500 at the Queen's Club Championships, his fourth ATP main draw but his first as a qualifier. In the first round, he defeated his second top 50 player, world No. 47 Kyle Edmund, before losing to world No. 14 Tomas Berdych. At Wimbledon in July, Shapovalov was awarded a wild card for the main draw. He was defeated by Jerzy Janowicz in the opening round. At the end of the month, he won his second ATP Challenger title, defeating compatriot Peter Polansky in the final of the 75K in Gatineau.

Example Input: Question: What age was Ancheta the year the first botnet-related prosecution in US history began? Passage:In 2006, Klausner presided over United States v. Ancheta, the federal prosecution of Jeanson James Ancheta of Downey, California, the first botnet-related prosecution in U.S history. Following Ancheta's guilty plea, Klausner sentenced Ancheta to 57 months in prison for various botnet-related crimes. In 2016, Klausner presided over a copyright case filed by the estate of Spirit guitarist Randy Wolfe against Led Zeppelin founders Robert Plant and Jimmy Page. The estate of Wolfe alleged that Wolfe was entitled to a writing credit for the song "Stairway to Heaven"; Klausner ruled in April 2016 that a jury could find "substantial similarity" between the elements of the two songs. In another copyright case arising from the Star Trek fan film Prelude to Axanar, Klausner rejected various motions by both parties in January 2017, setting the stage for a civil trial on the matter to go forward. The parties settled the suit. In August 2017, Klausner dismissed a class-action lawsuit filed by boxing fans who contended that the 2015 Floyd Mayweather Jr. vs. Manny Pacquiao boxing match was deceptively marketed because Pacquiao failed to disclose a shoulder injury that affected his performance. Klausner ruled that fans of sporting events have no right to have the event meet their expectations for excitement. In October 2017, Klausner ruled in favor of the plaintiff Coachella Music Festival in a lawsuit against the fledgling "Filmchella" film festival, finding that the names were likely to cause consumer confusion.
