fall spring summer winter
I gave my students this multiple choice question: There are some towns located in the valley of the Alpine mountains. During part of the year, these towns stay dark all day because the mountains block the Sun. During which season would the Sun be low enough in the sky that the village stays in the shadows?

Only one answer is correct among these 4 choices:
- fall
- spring
- summer
- winter

Could you tell me which one is correct?

winter
