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: How many years passed between the First Carlist War and the war that mostly in Catalonia? Passage:The Basque Country was one of the main sites of battles during the First Carlist War, a civil war between supporters of the Spanish regent Maria Christina, known as liberals, and those of the late king's brother Carlos of Borbon, known as Carlists. The Carlists were particularly focused on capturing Bilbao, a liberal and economic bastion in northern Spain. The Carlist general Tomas de Zumalacarregui tried to take the city during the Siege of Bilbao of 1835, but he was wounded during a battle near Begona and died some time after in the town of Zegama. The next year, the city resisted a second siege during which the liberal general Baldomero Espartero defeated the Carlists in the Battle of Luchana. The city was untouched by the Second Carlist War, which took place mostly in Catalonia, but was again an important scenario during the Third Carlist War; in April 1874 the city suffered a third siege which lasted two months.

Example Input: Question: How many years did Major General Haislip serve in the military? Passage:On 15 May 1942, five months after the United States entered World War II, the 85th Infantry Division was ordered into active military service at Camp Shelby, Mississippi, under the command of Major General Wade H. Haislip. Divisions in the U.S. Army at that time were "triangularized" with three combat regiments instead of the four regiment structure "square division" used during World War I. The 340th Infantry Regiment was redesignated as the 410th Quartermaster Battalion and left the division. Basic infantry training was begun in June 1942 at Camp Shelby, Mississippi. In April 1943, it participated in large-scale army training in the Louisiana Maneuvers near Leesville, Louisiana. In August, the division was moved to Camp Coxcomb, California for desert warfare training. In October, the division was transferred to Fort Dix, New Jersey, for final preparations before shipment overseas. Major General John B. Coulter was transferred as commander and retained this position throughout the war. The Assistant Division Commander (ADC) throughout the war was Brigadier General Lee S. Gerow.

Example Input: Question: Which river that bounded the "Gericht auf der Hohe" was the longest? Passage:The mediaeval historical development that Homberg experienced closely matches that experienced by neighbouring villages such as Kirrweiler, Deimberg, Buborn, Langweiler and Hausweiler. Like these places, Homberg belonged until 1140 to the Nahegau, and then thereafter until 1263 to the Waldgraviate, which itself had arisen from the Nahegau. As far as is now known, Homberg had its first documentary mention in 1319. In the document in question, an arbitrator confirmed that Waldgrave Friedrich of Kyrburg had to forgo all his claims to rights to Hoenberg and a series of other places in the "Gericht auf der Hohe" ("Court on the Heights"). The Gericht auf der Hohe was said to be a constituent district of the "Hochgericht auf der Heide" ("High Court on the Heath"), which comprised, roughly, lands in a triangle bounded by the Nahe, the Glan and the Steinalp (another river). The 1319 document dealt with a dispute between the two Waldgravial sidelines of Kyrburg and Dhaun-Grumbach. About 1344, in his own documents, the name "Friedrich von Hoenberg" appeared. He was obviously a nobleman who came from Homberg, but nothing else about him has come to light. The villages under the Gericht auf der Hohe, among which was Homberg, were pledged first, in 1363, by Johann von Dhaun to Sponheim-Starkenburg and then in 1443 by Waldgrave and Rhinegrave Friedrich to the last of the Counts of Veldenz, namely Friedrich III, whose daughter Anna married King Ruprecht's son Count Palatine Stephan. The document whereby this arrangement was laid out referred to the village's inhabitants as the "poor people of Grumbach". By uniting his own Palatine holdings with the now otherwise heirless County of Veldenz his wife had inherited the county upon her father Friedrich III's death in 1444, but not his comital title and by redeeming the hitherto pledged County of Zweibrucken, Stephan founded a new County Palatine, as whose comital residence he chose the town of Zweibrucken: the County Palatine later Duchy of Palatinate-Zweibrucken. Thus, Homberg, and the other villages, too, lay within this duchy, but they were all returned to the Waldgraviate in 1477 when the pledge was redeemed.
