Task: Question Generation
Input (English): Background Paragraph: Alberta's electrical demand varies throughout the day and across the seasons. When individuals are fixing supper and using home appliances, demand for power goes up, as it does during heat waves and cold snaps. It tapers off during spring and fall.

On Wednesday, a heat wave happened. On Thursday, it was normal. On Friday, a heat wave happened in the morning and a cold snap happened at night.
