Powdered sugar, also called confectioners' sugar, icing sugar, and icing cake, is a finely ground sugar produced by milling granulated sugar into a powdered state. It usually contains a small amount of anti-caking agent to prevent clumping and improve flow. Although most often produced in a factory, powdered sugar can also be made by processing ordinary granulated sugar in a coffee grinder, or by crushing it by hand in a mortar and pestle.
Solution: is confectionary sugar the same as powdered sugar?
Why? The question is a yes/no question, and it is answerable based on the given passage.

New input: The Beatles built their reputation playing clubs in Liverpool and Hamburg over a three-year period from 1960, with Stuart Sutcliffe initially serving as bass player. The core trio of Lennon, McCartney and Harrison, together since 1958, went through a succession of drummers, including Pete Best, before asking Starr to join them in 1962. Manager Brian Epstein moulded them into a professional act, and producer George Martin guided and developed their recordings, greatly expanding the group's popularity in the United Kingdom after their first hit, ``Love Me Do'', in late 1962. They acquired the nickname ``the Fab Four'' as Beatlemania grew in Britain over the next year, and by early 1964 became international stars, leading the ``British Invasion'' of the United States pop market. From 1965 onwards, the Beatles produced increasingly innovative recordings, including the albums Rubber Soul (1965), Revolver (1966), Sgt. Pepper's Lonely Hearts Club Band (1967), The Beatles (also known as the ``White Album'', 1968) and Abbey Road (1969). After their break-up in 1970, they each enjoyed success as solo artists. Lennon was shot and killed in December 1980, and Harrison died of lung cancer in November 2001. McCartney and Starr remain musically active.
Solution:
are there any of the beatles still alive?
