Mis amigos sugieren que centro deportivo a las dos de la tarde

Mis amigos sugieren que nosotros  al centro deportivo a las dos de la tarde.

Translation:

"My friends suggest that we [blank] the sports center at two in the afternoon."

The blank should be filled with the words "go to". The infinitive for "to go" in Spanish is ir; this must be conjugated for the masculine plural subject (nosotros). This sentence has an imperative mood (it makes a suggestion). The masculine plural conjugation of ir for nosotros in imperative mood is vayamos.

Mis amigos sugieren que nosotros vayamos al centro deportivo a las dos de la tarde.

Incorrect. the right answer is "su nieto estudia la lecciòn"
