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 monarch involved in the Byzantine-Bulgarian wars was born first? Passage:With the ascendance of Simeon I to the throne in 893, the long-lasting peace with the Byzantine Empire established by his father was about to end. A conflict arose when Byzantine Emperor Leo VI the Wise, acting under pressure from his wife Zoe Zaoutzaina and her father, Stylianos Zaoutzes, moved the marketplace for Bulgarian goods from Constantinople to Thessaloniki, where Bulgarian merchants were heavily taxed. Forced to take action, in the autumn of 894 Simeon invaded the Byzantine Empire from the north, meeting little opposition due to the concentration of most Byzantine forces in eastern Anatolia to counter Arab invasions. Informed of the Bulgarian offensive, the surprised Leo sent an army consisting of guardsmen and other military units from the capital to halt Simeon, but his troops were routed somewhere in the theme of Macedonia.The Magyars managed to defeat Simeon's army twice, but in 896 they were routed in the Battle of Southern Buh. The war ended in 896 with a great Bulgarian victory near Bulgarophygon in Eastern Thrace. The market was returned to Constantinople, and the Byzantine Emperor had to pay annual tribute to Bulgaria. More importantly, with help from the Pechenegs Simeon successfully fended off a Magyar invasion, which was coordinated with the Byzantines.

Example Input: Question: How many of the judges of the season of the show Boyd won were also judges in that show's first season? Passage:In the first issue of Billboard of the year, Craig Wayne Boyd entered the Hot Country Songs chart at number one with "My Baby's Got a Smile on Her Face". Boyd, winner of season 7 of NBC's reality TV singing competition The Voice, was only the second artist in the chart's 57-year history to enter at number one. After holding the top spot for a single week, however, the song achieved the unusual feat of dropping off the chart entirely the following week. In addition to Boyd, one other artist was a first-time chart-topper on Hot Country Songs. Following a critically acclaimed performance at the 49th Country Music Association (CMA) Awards, Chris Stapleton's version of "Tennessee Whiskey", which had spent a single week at number 46 six months earlier, re-entered at number one, despite never having been officially released as a single or serviced to radio. Nine acts gained their first career country number ones by topping the airplay listing. Ashley Monroe made her first appearance at number one under her own name when she featured on Blake Shelton's hit "Lonely Tonight", although she had previously reached the top spot as part of the group Pistol Annies, who had been featured on another of Shelton's songs two years earlier. Between May and August, Tyler Farr, Kelsea Ballerini, Canaan Smith, Michael Ray, and the band A Thousand Horses were all first-time chart-toppers, as was Grace Potter, who was featured on veteran country star Kenny Chesney's song "Wild Child". Later in the year, the band Old Dominion and the duo Dan + Shay made their first appearances at number one.

Example Input: Question: In which country is the material excavated from Mureybet stored? Passage:The first archaeological investigation of the site was carried out in 1964. In that year, the site was noted during an archaeological survey of the region directed by Maurits N. van Loon of the Oriental Institute of the University of Chicago, and a small sounding was made. In 1965, a more extensive excavation was carried out, again under the direction of Van Loon. Between 1971 and 1974, work on the site was resumed by a team of the French Centre national de la recherche scientifique (CNRS) directed by Jacques Cauvin. All excavations were part of the larger international – and eventually UNESCO-coordinated – effort to investigate as many archaeological sites as possible in the area that would be flooded by Lake Assad, the reservoir of the Tabqa Dam, which was being built at that time. The filling of Lake Assad eventually led to the flooding of Mureybet in 1976. Although the site is now submerged and no longer accessible, the material that has been retrieved during the excavations continues to generate new research. This material is currently stored at the National Museum of Aleppo and the Institute de Préhistoire Orientale in Jalès-Berrias in France.
