Task: Question Generation
Input (English): Background Paragraph: During May, June, and July, the Northern Hemisphere is exposed to more direct sunlight because the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to seasonal lag, June, July, and August are the warmest months in the Northern Hemisphere while December, January, and February are the warmest months in the Southern Hemisphere. 
Story: Stan moved from the US to Australia, and he still gets confused because of the seasons in the southern hemisphere and the fact that they use the same calendar as the rest of the world.
Output (English): Which month is colder in the northern hemisphere, June or December?
