Analyze the sentence structure

The sentence is "Keiko visitó a [blank]". The verb is visitó (visited), followed by the preposition a.

Apply grammatical rules

In Spanish, the preposition a is used as the "personal a" when the direct object of a verb is a specific person or a pet. Using Context Clues, we must find a noun representing a person.

Evaluate the options

• el aeropuerto (the airport) is a place, so it does not use the personal a.
• cena (dinner) is an event/thing, so it does not use the personal a.
• largo (long) is an adjective.
• su amiga (her friend) is a person, which requires the personal a.

Select the correct answer

Using Spanish Vocabulary, su amiga fits grammatically and semantically after "visitó a".
