Answer:
Hace dos días que Federico se cayó y tuvo dolor en la espalda. tuve tuvo tuvimos tuviste.
Explanation:
The sentence is referring to an action in the past that happened to a third person (Federico). This is why the conjugation of the verb “tener” that must be used in the second part of the sentence must be “tuvo”.
On the other hand, the verbs “tuve”, “tuvimos” and “tuviste”, -although conjugated in past tense- are used when talking about other personal pronouns, as follows:
“Tuve”: when talking in first person (“yo”).
“Tuvimos”: when talking in the first person of the plural (“nosotros”).
“Tuviste”: when talking in second person (“tú”).
