Rain will fall. Hurricanes will form. Lightning will strike. Hail will form.
I gave my students this multiple choice question: Above a continent, a warm air mass slowly passes over a cold air mass. As the warm air begins to cool, clouds form. What will most likely happen next?

Only one answer is correct among these 4 choices:
- Rain will fall.
- Hurricanes will form.
- Lightning will strike.
- Hail will form.

Could you tell me which one is correct?

Rain will fall.
