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: Which countries made up the group that invaded Yugoslavia? Passage:On 6April 1941, Yugoslavia was invaded from all sides by the Axis powers, led by German forces. Stojanovic was assigned as a physician to an infantry battalion based in Banja Luka. For several days after the invasion this battalion moved toward Dalmatia, before it completely disintegrated without fighting the enemy, and Stojanovic returned to Prijedor. The Royal Yugoslav Army capitulated on 17April, and the Axis powers proceeded to dismember Yugoslavia. Almost all of modern-day Croatia, all of modern-day Bosnia-Herzegovina, and parts of modern-day Serbia were combined into a puppet state called the Independent State of Croatia (, NDH). It was an "Italian-German quasi-protectorate", which was controlled by the fascist Ustase led by Ante Pavelic. One of its policies was to eliminate the ethnic Serb population of the NDH through mass killings, expulsions and forced assimilation, and many Serbs fled from the NDH to the German-occupied territory of Serbia.

Example Input: Question: Did Louis XIV's cousin have any siblings? Passage:After Louis XIV's marriage to Maria Theresa of Spain on 9 June 1660, Queen Anne turned her attention to the marriage of Philippe. He had previously been encouraged to court his older cousin the Duchess of Montpensier, eldest daughter of Gaston and his first wife Marie de Bourbon. Known as Mademoiselle at this time, she had an immense private fortune and had previously rejected suitors such as Charles II of England. Born in 1627, she was the sole heiress of her mother who died in childbirth. Mademoiselle declined the union, complaining that Philippe always stayed near his mother as if he was "like a child". Mademoiselle instead remained unmarried. Philippe would marry instead another first cousin, Princess Henrietta of England, youngest child of King Charles I of England and his wife Queen Henrietta Maria, who was Philippe's aunt and had taken refuge at the court of France after the birth of Princess Henrietta in 1644. They lived at the Palais Royal and at the Palais du Louvre. In 1660, after the restoration of the House of Stuart to the throne of England under her brother Charles II, Princess Henrietta returned to England to visit her sister, the Princess of Orange, who later caught smallpox and died. The French court officially asked for Henrietta's hand on behalf of Philippe on 22 November 1660 while she was in England. The couple signed their marriage contract at the Palais Royal on 30 March 1661. The ceremony took place the next day in the same building in front of select members of the court. The dowry promised was a huge 840,000 livres. Known as Henriette d'Angleterre in France, and Minette to her intimates, she was known officially as Madame and was ever popular with the court. Court gossip later said that the king was the father of Henrietta's first child. Henrietta's very open flirting is said to have caused a jealous Philippe to retaliate by beginning to flaunt his sexuality openly in a less than accepting era.

Example Input: Question: When was the borough that contains the northern terminus of PA 103 incorporated? Passage:PA 103 reaches the residential community of Mattawana, where it passes through two S-curves to the northwest before making a turn to the east at the intersection with John Street, which heads west across the Juniata River to the borough of McVeytown. The route passes through an S-curve to the southeast and runs through farmland, making a turn to the northeast. The road runs through more rural land and winds east, turning northeast to pass through the community of Pine Glen. PA 103 continues northeast through the community of Longfellow before the Juniata River and Norfolk Southern's Pittsburgh Line closely parallel the road to the northwest, with Blue Mountain located to the southeast of the road. The route enters Granville Township and the river and railroad line head further away from the road as it passes through a mix of farmland and woodland with some homes a short distance northwest of Blue Mountain. Farther northeast, PA 103 runs north-northeast through forests with some homes east of the Juniata River. The river curves to the west and the route runs northeast through wooded areas with homes, coming to an intersection with the western terminus of PA 333. Past this intersection, the road heads north-northwest through forests and forms the border between Granville Township to the west and the borough of Juniata Terrace to the east. PA 103 turns northeast onto Delaware Avenue and passes between homes and some businesses to the northwest and woodland to the southeast. The route turns north and leaves Juniata Terrace for Granville Township again as it comes to a bridge over Norfolk Southern's Pittsburgh Line a short distance east of the Lewistown station serving Amtrak's Pennsylvanian train in the community of Lewistown Junction. The road passes north-northwest through residential and commercial areas in Lewistown Junction as an unnamed road, crossing a Juniata Valley Railroad line. PA 103 curves north and crosses the Juniata River into the borough of Lewistown, where it immediately comes to its northern terminus at an intersection with US 22 Bus.
