Task: Question Answering
Input (English): passage: 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.
 question: does it have to rain to have lightning?
Output (English): No
