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.

[EX Q]: 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.

[EX Q]: Question: What does it mean to have a perfect game in baseball? Passage:On May 26, 1959, in the 13th inning of a game against the Pittsburgh Pirates at Milwaukee County Stadium, Mantilla ruined Harvey Haddix's bid for a perfect game. Leading off the inning, he hit a ground ball to third baseman Don Hoak, whose throw to first pulled Rocky Nelson off the bag for an error. (Mantilla had not even been in the starting lineup; he entered the game in the 11th after Del Rice had pinch-hit for Johnny O'Brien.) Mantilla was sacrificed to second by Eddie Mathews, followed by an intentional walk to Hank Aaron. The following batter, Joe Adcock, hit one over the right-center field wall, just beyond the reach of right fielder Joe Christopher (who was making his Major League debut), for an apparent 30 victory. Mantilla scored the winning run, but Aaron, thinking the ball was still in play and that the game ended when Mantilla scored the winning run, rounded second and then headed for the dugout. Adcock, running out his home run, passed Aaron on the bases; as a result, the ruling from National League president Warren Giles was that Adcock's hit was a double (not a home run), only Mantilla's run counted and the final score was 10.
