Analyze the sentence structure

The sentence is: ¿Están ________ los vendedores en la oficina?
We need to find the correct form of the word meaning "all" to modify the subject.

Identify the subject and its properties

Using our Spanish Vocabulary knowledge, the subject of the sentence is los vendedores (the salesmen/sellers).

• Gender: Masculine (indicated by the article los and ending -ores).
• Number: Plural (indicated by the plural article los and ending -es).

Apply gender and number agreement

In Spanish, adjectives and quantifiers must agree in gender and number with the noun they modify.

• todo (masculine singular)
• toda (feminine singular)
• todos (masculine plural)
• todas (feminine plural)

Since los vendedores is masculine plural, the matching form is todos.
