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: A dry thunderstorm or heat storm is a thunderstorm that produces thunder and lightning, but most or all of its precipitation evaporates before reaching the ground. Dry lightning refers to lightning strikes occurring in this situation. Both are so common in the American West that they are sometimes used interchangeably. The latter term is a technical misnomer since lightning itself is neither wet nor dry.
Student:
does it have to rain to have lightning?
