Example input: 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.
Example output: is confectionary sugar the same as powdered sugar?
Example explanation: The question is a yes/no question, and it is answerable based on the given passage.
Q: Article III of the United States Constitution does not specify the number of justices. The Judiciary Act of 1789 called for the appointment of six ``judges''. Although an 1801 act would have reduced the size of the court to five members upon its next vacancy, an 1802 act promptly negated the 1801 act, legally restoring the court's size to six members before any such vacancy occurred. As the nation's boundaries grew, Congress added justices to correspond with the growing number of judicial circuits: seven in 1807, nine in 1837, and ten in 1863.
A:
does the constitution specify the number of justices?
