Task: Question Generation
Input (English): Close to Richmond Park is Kew Gardens which has the world's largest collection of living plants. In 2003, the gardens were put on the UNESCO list of World Heritage Sites. There are also numerous parks administered by London's borough Councils, including Victoria Park in the East End and Battersea Park in the centre. Some more informal, semi-natural open spaces also exist, including the 320-hectare (790-acre) Hampstead Heath of North London, and Epping Forest, which covers 2,476 hectares (6,118.32 acres) in the east. Both are controlled by the City of London Corporation. Hampstead Heath incorporates Kenwood House, the former stately home and a popular location in the summer months where classical musical concerts are held by the lake, attracting thousands of people every weekend to enjoy the music, scenery and fireworks. Epping Forest is a popular venue for various outdoor activities, including mountain biking, walking, horse riding, golf, angling, and orienteering.
