Example Input: Question: Which monarch involved in the Byzantine-Bulgarian wars was born first? Passage:With the ascendance of Simeon I to the throne in 893, the long-lasting peace with the Byzantine Empire established by his father was about to end. A conflict arose when Byzantine Emperor Leo VI the Wise, acting under pressure from his wife Zoe Zaoutzaina and her father, Stylianos Zaoutzes, moved the marketplace for Bulgarian goods from Constantinople to Thessaloniki, where Bulgarian merchants were heavily taxed. Forced to take action, in the autumn of 894 Simeon invaded the Byzantine Empire from the north, meeting little opposition due to the concentration of most Byzantine forces in eastern Anatolia to counter Arab invasions. Informed of the Bulgarian offensive, the surprised Leo sent an army consisting of guardsmen and other military units from the capital to halt Simeon, but his troops were routed somewhere in the theme of Macedonia.The Magyars managed to defeat Simeon's army twice, but in 896 they were routed in the Battle of Southern Buh. The war ended in 896 with a great Bulgarian victory near Bulgarophygon in Eastern Thrace. The market was returned to Constantinople, and the Byzantine Emperor had to pay annual tribute to Bulgaria. More importantly, with help from the Pechenegs Simeon successfully fended off a Magyar invasion, which was coordinated with the Byzantines.

Example Input: Question: Of the two singles from the discography, which one charted the highest? Passage:The discography of Scottish rock band The Twilight Sad consists of five studio albums, four compilation albums, fifteen singles, and five extended plays (EPs). The band currently consists of James Graham (vocals, lyrics), Andy MacFarlane (guitar, production), Johnny Docherty (bass), Brendan Smith (keyboards) and Sebastien Schultz (drums). The Kilsyth-based band formed in 2003 and were signed to Fat Cat Records when Alex Knight, co-founder of the label, went to Glasgow to watch the band perform their third gig and signed them on the spot. The band released their debut EP The Twilight Sad in November 2006 in the United States only, followed by their debut album Fourteen Autumns & Fifteen Winters in April 2007, which garnered widespread critical acclaim. The album spawned two singles, "That Summer, at Home I Had Become the Invisible Boy" in April, and "And She Would Darken the Memory" in July. The following year, the band released Here, It Never Snowed. Afterwards It Did, a mini-album of reworked versions of songs from Fourteen Autumns & Fifteen Winters and two non-album tracks, inspired by stripped-down live performances. A collection of live versions and previously unreleased tracks entitled Killed My Parents and Hit the Road was released in December 2008. The Twilight Sad's second studio album, Forget the Night Ahead, was released in September 2009 to further acclaim and marked a shift in the band's direction towards a darker and more streamlined sound. The album produced three singles: "I Became a Prostitute" in August 2009, "Seven Years of Letters" in October 2009, and "The Room" in April 2010. Founding bassist Craig Orzel left the band in February 2010, and the band released The Wrong Car EP in September of that year.
