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: Where is the entity located that the two Phillies pitchers were inducted into? Passage:Of those Phillies, 97 have had surnames beginning with the letter R. Two of those players have been inducted into the Baseball Hall of Fame: pitcher Eppa Rixey, who was a Phillie for six seasons in two different stints (1912–1917, 1919); and Robin Roberts, who won 20 games during the 1950 season as the ace pitcher of the Whiz Kids. The Hall of Fame lists the Phillies as Roberts' primary team; during his career, the right-hander won 234 games and lost 199, the latter one of his three franchise records. During his 14 seasons with the team, he pitched 3,739  innings and completed 272 games, both records; he also held the major league record for most career home runs allowed until it was broken in 2010. Roberts was also elected to the Philadelphia Baseball Wall of Fame as the Phillies' first inductee in 1978.

Example Input: Question: Which major French city near Aurillac has a larger population? Passage:Aurillac is at above sea level and located at the foot of the Cantal mountains in a small Sedimentary basin. The city is built on the banks of the Jordanne, a tributary of the Cère. It is south of Paris and north of Toulouse. Aurillac was part of a former Auvergne province called Haute-Auvergne and is only away from the heart of the Auvergne Volcano Park. Access to the commune is by numerous roads including the D922 from Naucelles in the north, the D17 from Saint-Simon in the north-east, Route nationale N122 from Polminhac in the east which continues to Sansac-de-Marmiesse in the south-west, the D920 to Arpajon-sur-Cère in the south-east, and the D18 to Ytrac in the west. The Figeac-Arvant railway passes through the commune with a station in the centre of town but there is no TGV service. About 50% of the commune is urbanised with farmland to the east and west of the urban area.

Example Input: Question: What city was the battle in that the 16th Indiana Volunteer Infantry fought in the Eastern Theater? Passage:On May 20, 1861, when the Civil War began, Indiana Governor Oliver P. Morton appointed Hackleman colonel of the 16th Indiana Volunteer Infantry of one-year volunteers. Hackleman and the 16th Indiana were sent to the Eastern Theater where they were engaged at the Battle of Ball's Bluff. On April 28, 1862 he was promoted to brigadier general of volunteers and ordered to report to Ulysses S. Grant in the Western Theater. Hackleman was assigned to command the 1st Brigade in the 2nd Division of the Army of the Tennessee. The 2nd Division, led by Thomas A. Davies, was temporarily attached to William S. Rosecrans' Army of the Mississippi stationed around Corinth, Mississippi. On October 3, the Confederate Army attacked Rosecrans. Early in the fighting the Confederates forced a gap between Davies and General Thomas J. McKean's divisions and the Union line began to fall back. At this point in the battle Hackleman attempted to rally his brigade and was shot through the neck. He was taken to the Tishomingo Hotel in Corinth where he lay dying from the mortal wound. His final words were: "I am dying, but I die for my country". His body was returned to his home in Rushville where he was buried. He was the only Indiana general to be killed in battle during the Civil War.
