Answer:
Tu y yo estamos en Bolivia.
Explanation:
(Sorry in advance for the lack of accent marks)
Tu y yo = you and me. This is also known as "we", or nosotros.
So, if we reread the sentence as Nosotros ___ en Bolivia, we can conjugate estar. In this case, the present tense conjugation for estar would be estamos.
Hope this helps!
1. dirijo
2. Tengo
3. salgo
4. Creo
the second one makes more sense
