I gave my students this multiple choice question: A full Moon is observed in Buffalo, New York, on June 1. Approximately when will the next full Moon be observed in Buffalo?

Only one answer is correct among these 4 choices:
- June 7
- June 15
- July 1
- July 7

Could you tell me which one is correct?

July 1
