Answer:

Explanation:
The sentences above were completed with the correct conjugation of the verb "être", which means "to be". The verbs were conjugated according to the numbers related to the pronouns that are the subjects of the sentences. In addition, verbs were used in the present tense, since the question did not specify how they should be used.
