Teacher: You will be given a passage, and your task is to generate a Yes/No question that is answerable based on the given passage.
Teacher: Now, understand the problem? If you are still confused, see the following example:
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?
Reason: The question is a yes/no question, and it is answerable based on the given passage.

Now, solve this instance: Unreported employment; working under the table, off the books, cash-in-hand, illicit work or (in UK English) moonlighting, is illegal employment that is not reported to the government. The employer or the employee often does so for tax evasion or avoiding or violating other laws. The working contract is made without social security costs, and does typically not provide health insurance, paid parental leave, paid vacation or pension funds. It is a part of what has been called the underground economy, shadow economy, black market or the non-observed economy.
Student:
is it illegal to be paid off the books?
