Task: Question Generation
Input (English): Passage: Chersonesus' ancient ruins are presently located in one of Sevastopol's suburbs. They were excavated by the Russian government, starting from 1827. They are today a popular tourist attraction, protected as an archaeological park. The buildings mix influences of Greek, Roman and Byzantine culture. The defensive wall was approximately 3.5 kilometres  long, 3.5 to 4 metres wide and 8 to 10 metres high with towers at a height of 10 to 12 metres. The walls enclosed an area of about 30 hectares . Buildings include a Roman amphitheatre and a Greek temple. The surrounding land under the control of the city, the chora, consists of several square kilometres of ancient but now barren farmland, with remains of wine presses and defensive towers. According to archaeologists, the evidence suggests that the locals were paid to do the farm work instead of being enslaved. The excavated tombstones hint at burial practices that were different from the Greek ones. Each stone marks the tomb of an individual, instead of the whole family and the decorations include only objects like sashes and weapons, instead of burial statues. Over half of the tombs archaeologists have found have bones of children. Burned remnants suggest that the city was plundered and destroyed. In 2007, Chersonesus tied for fifth in the Seven Wonders of Ukraine poll. On February 13, 2009, Ukrainian Defence Minister Yuriy Yekhanurov called on Russia's Black Sea naval fleet to move its automobile depot from the site to another place. The location of the Russian Black Sea naval fleet's automobile depot was one of the obstacles to the inclusion of the reserve on UNESCO's list of world heritage sites.
