Question

1. vamos a ________ en la piscina.

nadar
nadan
nadamos
nado

Explanation:

Analyze the sentence structure

The sentence is "Vamos a ________ en la piscina." This uses the Spanish periphrastic future construction.

Identify the grammatical rule

The formula for the near future tense in Spanish is "ir + a + infinitive". Here, "Vamos" is the conjugated form of "ir" (we are going), followed by the preposition "a".

Select the correct verb form

The verb following "ir a" must be in its infinitive (unconjugated) form. The verb meaning "to swim" is "nadar".

Evaluate the options

• "nadar" is the infinitive form.
• "nadan" is conjugated (they swim).
• "nadamos" is conjugated (we swim).
• "nado" is conjugated (I swim).

Therefore, "nadar" is the correct choice.

Answer:

• nadar (Correct answer)
• nadan
• nadamos
• nado
