For this case we must complete the sentence according to the options given.
The questions refer to the second person singular, that is: You, which in Spanish is given by: Tú.
In Spanish, the indefinite preterit verb tense for the second person singular has the form:
Tú inscribiste
Tú hablaste
Thus, the complete sentence is:
¿Te inscribiste para la clase de baile? ¿Con quién hablaste?
In English it is translated as:
Did you sign up for the dance class? Who did you speak with?
