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: Which son was born first? Passage:Darius was the son of Hystaspes and the grandson of Arsames. Both men belonged to the Achaemenid tribe and were still alive when Darius ascended the throne. Darius justifies his ascension to the throne with his lineage. He claimed he could trace his ancestors back to Achaemenes, even though he was only distantly related. With this in mind, Darius married Atossa, daughter of Cyrus, with whom he had four sons: Xerxes, Achaemenes, Masistes and Hystaspes. He also married Artystone, another daughter of Cyrus, with whom he had two sons, Arsames and Gobryas. Darius married Parmys, the daughter of Bardiya, with whom he had a son, Ariomardus. Furthermore, Darius married Phratagune, with whom he had two sons, Abrokomas and Hyperantes. He also married another woman of the nobility, Phaidyme, the daughter of Otanes. It is unknown if he had any children with her. Before these royal marriages, Darius had married an unknown daughter of his good friend and lance carrier Gobryas from an early marriage, with whom he had three sons, Artobazanes, Ariabignes and Arsamenes. Any daughters he had with her are not known. Although Artobazanes was Darius's first-born, Xerxes became heir and the next king through the influence of Atossa; she had great authority in the kingdom as Darius loved her the most of all his wives.

Example Input: Question: How much were KSEE's non-license assets purchased for by the  Nexstar Broadcasting Group? Passage:On February 6, 2013, Granite sold KSEE's non-license assets to the Nexstar Broadcasting Group, with Nexstar also intending to purchase KSEE's license following Federal Communications Commission approval; in the interim, Nexstar operated the station via a time brokerage agreement. The deal made KSEE a sister station to CBS affiliate KGPE, which Nexstar had just acquired from Newport Television. Normally, duopolies between two "Big Four" affiliates, let alone "Big Three," would not be allowed because those stations are usually the four highest-rated stations in a market, which FCC regulations do not allow any common ownership of. However, according to Nielsen, in 2013 KGPE was ranked as the fourth highest-rated station in the market and KSEE fifth, after KFSN (ABC), KFTV (Univision), and KMPH-TV (Fox), allowing a duopoly to be formed between the stations. This marked the second instance (after the Gannett Company purchased ABC affiliate WJXX in Jacksonville, Florida, creating a duopoly with that market's NBC affiliate WTLV, in 2000) in which a single company owns a duopoly involving two stations that are affiliated by a Big Three television network; and is also Nexstar's first true Big Three duopoly (Nexstar's other Big Three duopolies are virtually formed, in which the other station is owned by Mission Broadcasting). The merger was approved on April 17, and completed by May 31.

Example Input: Question: What job did James Dobson hold the year his brother died? Passage:He was born at Plymouth, the eldest son of George Clarisse Dobson, a civil engineer, of French descent. When he was about eight, the family moved to Holyhead, and his first school was at Beaumaris in Anglesey. He was later educated at Coventry, and the Gymnase, Strasbourg. He returned at the age of sixteen with the intention of becoming a civil engineer. (His younger brother James would in fact become a noted engineer, helping complete the Buenos Aires harbour works in the 1880s and 1890s.) At the beginning of his career, he continued to study at the South Kensington School of Art, in his spare time, but without definite ambition. In December 1856 he entered the Board of Trade, gradually rising to the rank of principal in the harbour department, from which he retired in the autumn of 1901. In 1868, he had married Frances Mary, daughter of the distinguished civil engineer Nathaniel Beardmore (1816–1872) of Broxbourne, Hertfordshire, and settled at Ealing. Dobson died in 1921 and his funeral was held on 6 September at St Peter's Church, Ealing. He is buried in the Westminster Cemetery, Uxbridge Rd, Hanwell, Middlesex.
