In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it. Your job is to determine which sentence(s) from the passage can be used to search for further information needed to answer the question.

Example Input: Question: How many more troops were at the fight in 591 than the one in 586? Passage:Maurice had to continue the war against the Persians. In 586 his troops defeated them at the Battle of Solachon south of Dara. In 588, a mutiny by unpaid Byzantine troops against their new commander, Priscus, seemed to offer the Sassanids a chance for a breakthrough, but the mutineers themselves repulsed the ensuing Persian offensive. Later in the year they secured a major victory before Martyropolis. The Sassanid commander, Maruzas, was killed, several of the Persian leaders were captured along with 3,000 other prisoners, and only a thousand men survived to reach refuge at Nisibis. The Byzantines secured much booty, including the Persian battle standards, and sent them, along with Maruzas' head, to Maurice in Constantinople. In 590 two Parthian brothers, Vistahm and Vinduyih, overthrew King Hormizd IV and made the latter's son, Prince Khosrau II, the new King. The former Persian commander-in-chief, Bahram Chobin, who had rebelled against Hormizd IV, claimed the throne for himself and defeated Khosrau. Khosrau and the two Parthians fled to the Byzantine court. Although the Senate unanimously advised against it, Maurice helped Khosrau regain his throne with an army of 35,000 men. In 591 the combined Byzantine-Persian army under generals John Mystacon and Narses defeated Bahram Chobin's forces near Ganzak at the Battle of Blarathon. The victory was decisive; Maurice finally brought the war to a successful conclusion with the re-accession of Khosrau.

Example Output: In 586 his troops defeated them at the Battle of Solachon south of Dara

Example Input: Question: How many years after the discovery of pulsars did Lyne retire? Passage:Andrew Geoffrey Lyne FRS (born 13 July 1942) is a British physicist. Lyne is Langworthy Professor of Physics in the School of Physics and Astronomy, University of Manchester, as well as an ex-director of the Jodrell Bank Observatory. Despite retiring in 2007 he remains an active researcher within the Jodrell Bank Pulsar Group. Lyne was educated at The Portsmouth Grammar School, the Royal Naval School, Tal Handaq, Malta and at St. John's College at the University of Cambridge (natural sciences), continuing to the University of Manchester for a PhD in Radio Astronomy. Lyne writes that he is "mostly interested in finding and understanding radio pulsars in all their various forms and with their various companions. Presently, I am most occupied with the development of new multibeam search systems at Jodrell and Parkes, in order to probe deeper into the Galaxy, particularly for millisecond pulsars, young pulsars and any that might be in binary systems."

Example Output: Despite retiring in 2007 he remains an active researcher within the Jodrell Bank Pulsar Group

Example Input: Question: In what county is the city located where Henson was born? Passage:Brian David Henson was born in New York City, is the first born son of Jane Henson (née Nebel; 1934–2013) and Jim Henson (1936–1990). He has four siblings: Lisa (born 1960), Cheryl (born 1961), John (1965–2014), and Heather Henson (born 1970). As a child, he made several cameo appearances in some of the filmed segments his father produced for the PBS children's series Sesame Street, most notably in various segments of the "Number Song Series." As he got older, he built the very first Muppet penguin puppet for the opening "Lullaby of Broadway" segment of a season three episode of The Muppet Show, guest starring Gilda Radner. During his summer break from high school in 1980, he assisted in the bicycle sequence from The Great Muppet Caper (1981). He helped create and operate a special rigging device that was created to allow the Muppets to ride bicycles since he was skilled in the use of marionette puppets. A few years later, he similarly operated a marionette of Scooter riding a bicycle in The Muppets Take Manhattan (1984).

Example Output:
