Task: Question Generation
Input (English): Passage: Located on the Gulf of Antalya on the Anatolian coastal plain of Pamphylia, the town is situated between the Taurus Mountains to the north and the Mediterranean Sea, and is part of the Turkish riviera, occupying roughly 70 kilometres (43 mi) of coastline. From west to east, the Alanya district is bordered by the Manavgat district along the coast, the mountainous Gündoğmuş inland, Hadim and Taşkent in the Province of Konya, Sarıveliler in the Province of Karaman, and the coastal Gazipaşa district. Manavgat is home to the ancient cities of Side and Selge. East of the city, the Dim River flows from the mountains in Konya on a south-west route into the Mediterranean.
The Pamphylia plain between the sea and the mountains is an isolated example of an Eastern Mediterranean conifer-sclerophyllous-broadleaf forest, which include Lebanon Cedar, evergreen scrub, fig trees, and black pine. The Alanya Massif refers to the area of metamorphic rocks east of Antalya. This formation is divided into three nappes from lowest to highest, the Mahmutlar, the Sugözü, and the Yumrudağ. The similar lithology extends beneath the city in a tectonic window. Bauxite, an aluminum ore, is common to the area north of city, and can be mined.
The town is divided east–west by a rocky peninsula, which is the distinctive feature of the city. The harbor, city center, and Keykubat Beach, named after the Sultan Kayqubad I, are on the east side of the peninsula. Damlataş Beach, named for the famous "dripping caves", and Kleopatra Beach are to the west. The name "Cleopatra" possibly derives from either the Ptolemaic princess' visit here or the area's inclusion in her dowry to Mark Antony. Atatürk Bulvarı, the main boulevard, runs parallel to the sea, and divides the southern, much more touristic side of Alanya from the northern, more indigenous side that extends north into the mountains. Çevre Yolu Caddesi, another major road, encircles the main town to the north.
Output (English): What is the full name of the person that the beach in the east side of the city is named after?
