In this task, you're given a passage, further information available on a particular linked term from the statement, and a question. Your job is to generate the answer to the question by using the information provided. If there is no clear answer obtainable, output 'none'.

Let me give you an example: Passage: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lo during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,

Passage: The Abbasid-era geographers report that the town was the centre of a flourishing agricultural region, with a number of dependent suburbs such as Qasr-i Ahnaf. According to al-Muqaddasi, who wrote in ca. 980, the locals were kin of the people of Gharjistan, and the town was a dependency of the rulers, or Shirs, of Gharjistan. A section of the Harbiyya district of the Round city of Baghdad was named Marwrudiyya () after the people from this city. The town continued to flourish under the Seljuk Empire, when the Seljuk ruler Ahmad Sanjar built the city a new wall, some 5,000 paces in circumference. The town and the surrounding area suffered during the constant conflicts between the Khwarazmshahs and the Ghurids in the late 12th century, and a battle was fought there between the Ghurid ruler Ghiyath al-Din Muhammad (r. 11631202) and his Khwarazmian rival Sultan Shah (r. 11721193) in 1190. Although the town appears to have escaped the destruction of Marw al-Shahijan by the Mongols, it fell into ruin under the Timurids and was largely abandoned.
