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.

Input: Consider Input: Question: What other types of fossils have been found in the Villaieja Formation? Passage:Anachlysictis gracilis is an extinct carnivorous mammal belonging to the group Sparassodonta, which were metatherians (a group including marsupials and their close relatives) that inhabited South America during the Cenozoic. Unlike other remains assigned to the family Thylacosmilidae (a group of metatherian predators equipped with "saber teeth") that had been found previously, Anachlysictis is the first record of such borhyaenoids in northern South America, and also most primitive and ancient in the family (in fact, is the first confirmed record that did not belong to the genus Thylacosmilus, until the official publication of Patagosmilus in 2010). This species was found in the Villavieja Formation in the area of La Venta in Colombia, a famous fossil deposit in the Middle Miocene (Laventan; 13.8-11.8 million years ago), based on fragments that include a front portion of the lower jaw, with an incipient molar tooth and a piece of carnassial from the front of the maxilla.

Input: Consider Input: Question: How long did the coach Bzdelik replaced coach the Wake Forest team? Passage:Wake Forest is generally regarded as a competitive program in men's basketball, frequently qualifying for the NCAA Men's Division I Basketball Championship (23 times in the school's history). They reached the Final Four once, in 1962. The school's famous basketball alumni include Billy Packer, a guard on the 1962 Final Four team who became far more famous as a basketball broadcaster; Tyrone Curtis "Muggsy" Bogues, the shortest player ever to play in the NBA; Randolph Childress, for his MVP performance in the 1995 ACC Tournament; Washington Wizards swingman Josh Howard; Miami Heat forward James Johnson; Chris Paul of the Oklahoma City Thunder, 2006 NBA Rookie of the Year Award,9-time NBA All-star; and two-time league MVP, Five-time NBA Champion and three-time NBA Finals MVP Tim Duncan, and Minnesota Timberwolves starting point guard and 2015 NBA all-star Jeff Teague. Lawrence Joel Veterans Memorial Coliseum is the home venue for the Demon Deacons basketball team. Skip Prosser, Wake Forest University's men's basketball coach since 2001, died in Winston-Salem on July 26, 2007. One of Prosser's assistant coaches, Dino Gaudio, was named to replace him. On April 13, 2010, Jeff Bzdelik was hired, taking the place of the recently fired Gaudio. Despite no post-season success (0 wins in 3 ACC Tournament attempts) and an 11–42 record against ACC competition over the first three years of his tenure, Athletic Director Ron Wellman announced that Bzdelik would return for a fourth season as coach. On March 20, 2014, Jeff Bzdelik resigned his position as head coach. On April 4, 2014, Wake Forest hired former NCAA Champion and NBA player Danny Manning as its new head coach.

Input: Consider Input: Question: What team won the Stanley cup the year after Vancouver lost to Boston? Passage:On June 25, 2010, during the 2010 NHL Entry Draft, Ballard was traded to the Vancouver Canucks (along with Victor Oreskovich) in exchange for Michael Grabner, Steve Bernier and Vancouver's first-round pick, the 25th overall selection ultimately used to select Quinton Howden. After spending two months of the off-season on crutches while recovering from surgery, he reported to the Canucks' training camp, but struggled in the pre-season. Four games into the regular season, he suffered a concussion after being hit into the boards by Los Angeles Kings forward Brad Richardson on October 16, 2010. He was subsequently sidelined for five games. However, upon returning to the lineup, his play continued to struggle. Averaging 13 minutes of ice time a game, he was eventually taken out of the lineup for four games in November by Canucks head coach Alain Vigneault. It marked the first time in his career he was a healthy scratch. After being re-insterted into the lineup, he scored his first goal as a Canuck in a 6–1 win against the San Jose Sharks on November 26. Several months later, Ballard suffered a sprained medial collateral ligament (MCL) in his right knee during a game against the Ottawa Senators on February 7, 2011. The injury resulted from opposing forward Milan Michalek tripping him from behind, which Canucks general manager Mike Gillis pointed out did not occur anywhere near the puck, alluding to the play as illegal and disrespectable. Ballard finished his first regular season with career lows in games played (65), goals (2), assists (5), points (7) and average ice time per game (15 minutes and 14 seconds). His individual struggles came amidst a franchise record season for the Canucks, who won the Presidents' Trophy as the NHL's regular season champion for the first time in team history. Entering the playoffs as the first seed in the West, the Canucks advanced past the Chicago Blackhawks, Nashville Predators and San Jose Sharks to qualify for the 2011 Stanley Cup Finals. Facing the Boston Bruins, Vancouver lost the Stanley Cup in Game 7. Over the team's 25 playoff games, Ballard dressed for 10. Playing only one game of the final two rounds, he dropped in the depth chart behind Aaron Rome and rookie Chris Tanev.
