In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: Where was the division based that was able to dig in for a defense of Bastogne? Passage:The 9th Armored Division landed in Normandy late in September 1944, and first went into the line, 23 October 1944, on patrol duty in a quiet sector along the Luxembourg-German frontier. When the Germans launched their winter offensive on 16 December 1944, the 9th, with no real combat experience, suddenly found itself engaged in heavy fighting. The Division saw its severest action at St. Vith, Echternach, and Bastogne, its units fighting in widely separated areas. Its stand at Bastogne held off the Germans long enough to enable the 101st Airborne Division to dig in for a defense of the city. After a rest period in January 1945, the Division prepared to drive across the Roer River. The offensive was launched on 28 February 1945 and the 9th crossed the Roer to Rheinbach, sending patrols into Remagen. On 7 March 1945, elements of the 9th Armored found that the Ludendorff Bridge was still standing. When German demolition charges failed to bring the bridge down, they crossed it, disarming and removing the remaining charges, which could have exploded at any time. The Division exploited the bridgehead, moving south and east across the Lahn River toward Limburg, where thousands of Allied prisoners were liberated from Stalag XIIA. The Division drove on to Frankfurt and then turned to assist in the closing of the Ruhr Pocket. In April it continued east, encircling Leipzig and securing a line along the Mulde River. The Division was shifting south to Czechoslovakia when the war in Europe ended on 9 May 1945. All units of CCB/9 AIB of the 9th Armored Division were awarded the Presidential Unit Citation for their actions in taking and defending the Ludendorff Bridge during the Battle of Remagen in World War II.

Example Input: Question: How old was the person who escaped to Africa when Cleopatra ascended to the throne? Passage:Caesar crossed the Rubicon accompanied by the XIII Legion to take power from the senate in the same way that Sulla had done in the past. Formally declared an enemy of the state, Caesar pursued the Senatorial party, now led by Pompey, who abandoned the city to raise arms in Greece. Cato was sent to Sicily to secure control of the grain supply. After securing control of Italy, Caesar sent the praetor Curio with four legions to Sicily. Cato's garrison was insufficient to withstand a force of this magnitude, he abandoned the island and went to Greece to join Pompey. After first reducing Caesar's army at the siege battle of Dyrrhachium, where Cato commanded the port, the army led by Pompey was ultimately defeated by Caesar in the Battle of Pharsalus (Cato wasn't present during the battle, Pompey had left him in command of Dyrrhachium). Cato and Metellus Scipio, however, did not concede defeat and escaped to the province of Africa with fifteen cohorts to continue resistance from Utica. Caesar pursued Cato and Metellus Scipio after installing the queen Cleopatra VII on the throne of Egypt, and in February 46 BC the outnumbered Caesarian legions defeated the army led by Metellus Scipio at the Battle of Thapsus. Acting against his usual strategy of clemency, Caesar did not accept surrender of Scipio's troops, but had them all slaughtered.

Example Input: Question: How old was Amar Singh's nephew when he was first deposed? Passage:Thanjavur was successfully conquered in 1674 by Ekoji I (1675–84), the Maratha feudatory of the sultan of Bijapur and half-brother of Shivaji (1627/30-80) of the Bhonsle dynasty. Ekoji founded the Thanjavur Maratha kingdom which ruled Thanjavur till 1855. The Marathas exercised their sovereignty over Thanjavur throughout the last quarter of the 17th and the whole of the 18th century. The Maratha rulers patronized Carnatic music. In 1787, Amar Singh, the regent of Thanjavur, deposed the minor Raja, his nephew Serfoji II (1787–93) and captured the throne. Serfoji II was restored in 1799 with the assistance of the British, who induced him to relinquish the administration of the kingdom and left him in charge of Thanjavur fort and surrounding areas. The kingdom was eventually absorbed into British India in 1855 by the Doctrine of Lapse when Shivaji II (1832–55), the last Thanjavur Maratha ruler, died without a legitimate male heir. The British referred to the city as Tanjore in their records. Five years after its annexation, the British replaced Negapatam (modern-day Nagapattinam) with Thanjavur as the seat of the district administration. Under the British, Thanjavur emerged as an important regional centre. The 1871 India census recorded a population of 52,171, making Thanjavur the third largest city in the Madras Presidency. After India's independence, Thanjavur continued as the district headquarters.
