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 country is the island of Samothrace in now? Passage:The sculptor is unknown, although Paul MacKendrick suggests that Pythokritos of Lindos is responsible. When first discovered on the island of Samothrace (then part of the Ottoman Empire and called Semadirek) and published in 1863, it was suggested that the Victory was erected by the Macedonian general Demetrius Poliorcetes after his naval victory at Cyprus, between 295 and 289 BC. The Archaeological Museum of Samothrace continues to follow these originally established provenance and dates. Ceramic evidence discovered in recent excavations has revealed that the pedestal was set up about 200 BC, though some scholars still date it as early as 250 BC or as late as 180. Certainly, the parallels with figures and drapery from the Pergamon Altar (dated about 170 BC) seem strong. The evidence for a Rhodian commission of the statue has been questioned, however, and the closest artistic parallel to the Nike of Samothrace are figures depicted on Macedonian coins. Samothrace was an important sanctuary for the Hellenistic Macedonian kings. The most likely battle commemorated by this monument is, perhaps, the Battle of Cos in 255 BC, in which Antigonus II Gonatas of Macedonia won over the fleet of Ptolemy II of Egypt.

Example Input: Question: Who was the coach of the team Tony Craig played against in his first game in the first division? Passage:Born in Greenwich, London, Craig came through the youth ranks at Millwall. Adept as a central defender or a left back, he received his maiden call into the first team squad for a First Division league match against Bradford City on 5 April 2003 and was an unused substitute during the 1–0 win. Craig made his professional debut with a starting appearance in a 3–3 draw with Nottingham Forest on 26 April 2003 and lasted 67 minutes before being substituted for Robbie Ryan. He started in the final game of the 2002–03 season at home to Coventry City and scored the first senior goal of his career in the 2–0 win, with the opener on 51 minutes. Craig began the 2003–04 season as a virtual ever-present, making 10 appearances, but he dropped out of the squad entirely in October 2003. He was again out of favour with manager Dennis Wise during the 2004–05 season and had to wait until 19 February 2005 for his first appearance, which came with a start in a 1–0 defeat to Stoke City and he finished the campaign with 10 appearances.

Example Input: Question: How many games did Luke Wall play for the Skelmersdale United in November 2015? Passage:Wall was born in Liverpool and started his career with Blackburn Rovers as a youth player joining at under-14 level. In the summer of 2015 he signed his first professional contract after completing his scholarship with the academy. In November 2015, he joined Northern Premier League Premier Division side Skelmersdale United on a one-month youth loan. In the summer of 2016 he was released by Blackburn and joined League Two side Accrington Stanley on a one-year contract following a trial. He was recommended to the club by former Blackburn teammate and Accrington player John O'Sullivan. He made his first team debut for the club in August 2016 as a second-half substitute for Sean McConville in the 3–0 defeat to Crewe Alexandra in an EFL Trophy group-stage match. After struggling to break through into the match-day squad, he returned to Skelmersdale for a second loan spell in September 2016. In February 2017, he was sent out on loan again, joining Northern Premier League Division One North side Clitheroe on a short-term deal. He made a total of seven appearances in all competitions during the loan spell, scoring twice in a 4–3 away win over Ramsbottom United. In March 2017, he was on the move again joining Northern Premier League Premier Division side Marine on loan until the end of the season.
