Complete the time traveler's rather embarrassing journal entry.

The time traveler was quite confused when he finally arrived ___ Ancient Rome, mostly because he was wearing a 1970s disco suit.

The correct answer is in.

We use "arrive in" when talking about arriving at a large geographic destination, such as a city, country, or empire (like Rome, Japan, or Paris).

Note: A very common mistake is saying "arrive to," but in English, we never use "to" with the verb "arrive"!
