ⅦII以下のカーニバルの起源についての文を読んでそれぞれの問題に答えなさい。 From Samba in Brazil to masked parties in Italy, carnival is a truly global event, and it is celebrated in over 50 countries around the world. Carnival originated as a festival in ancient Egypt to *usher out winter and celebrate the beginning of spring. When *Alexander the Great *conquered Egypt, the Ancient Greeks *adopted the festival.

The word, "carne" means "meat" in Latin, and "vale" means "good bye". In the Catholic calendar, “carne vale" is a *feast before the *fast of Lent.
