Past Tense: Essere or Avere as the auxiliary when using a modal and a reflexive verb
Both sentences below are in the past tense with a modal verb and a reflexive verb. They are in Level 4 - Session 8, in the English to Italian translation exercise.
I thought any combination of modal and reflexive verbs in the past tense need to use “essere” as the auxiliary verb. There may have been instruction that both “essere” and “avere” can be used with different structures.
I’m not sure whether only “essere” can be used” or if both “essere” and “avere” can be used and there’s a bug in the software. If both can be used, but the exercises only allow one, how do we know if advance with auxiliary and associated structure to use?
