Task: Question Answering
Input (English): Passage: El Hatillo Municipality lies at the southeast area of the city of Caracas and at the northwest corner of the State of Miranda; it is one of the state's 21 municipalities. El Hatillo is also within the jurisdiction of the Alcaldía Mayor, which has power over three adjacent municipalities of Miranda, and over Libertador Municipality in the Capital District. These five municipalities make up the city of Caracas. El Hatillo has a land size of 114 square kilometres (44 sq mi) – the third largest municipality in the capital.
The municipality's natural southern boundary is the Turgua range, spanning east to west and separating El Hatillo from the Baruta and Paz Castillo municipalities. Parallel to Turgua in the north is the Sabaneta range; the Prepo stream runs between the two ranges. North of the Sabaneta range, the Prepo stream feeds into the Tusmare stream, which ends in the Guaire river.
La Guairita stream flows into the Guaire in northeastern El Hatillo. The Guaire river is the eastern limit of the municipality, separating it from Sucre and Paz Castillo in the southeastern sector of El Hatillo. La Guairita serves as the northern boundary between El Hatillo and the municipalities of Baruta and Sucre. Limiting Baruta to the west, the boundaries of the municipality follow El Volcán, Pariaguán, La Mata and other peaks until they meet Turgua range in southeastern El Hatillo.The tallest peak in El Hatillo is Picacho de El Volcán (Spanish for "Peak of the Volcano"), at 1,490 meters (4,888 ft) above sea level, from where radio, television and telecommunication antennas serve Caracas. Despite its name, the mountain has had no recorded volcanic history. Other significant mountains in El Hatillo are Gavilán at 1,148 metres (3,766 ft), Topo de El Paují at 1,245 metres (4,085 ft) and Topo de Piedras Pintadas at 1,196 metres (3,924 ft).
