Составьте пожалуйста 3 вопроса к тексту ниже, на которые можно ответить только "Да" либо "Нет"
Banksy (no one knows his real name) is a British street artist who is famous for his graffiti that has appeared on walls and buildings in cities around the world. He also sometimes holds 'shows' of paintings, usually in warehouses. In February 2007, Sotheby's auction house in London auctioned six of Banksy's works, fetching almost £400,000 altogether. Later that year, Banksy won an art award, but he didn't turn up to collect it - he prefers to remain anonymous. Despite Banksy's 'success', there are many people who see his work as vandalism rather than art. They see graffiti as ugly, irresponsible and childish and they say Banksy encourages more people to do it. Many city councils remove Banksy's works from their walls but they cannot do anything when it is on private property. In fact, many people want to keep his work on the walls of their building as it adds value to the property because it is considered by many to be a valuable work of art.
