HELP ASAP

Pls help me this is indirect object pronouns and verbs

Ineed someone who has either taken the unidad 9 prueba_gramática quiz, or at the very least, knows the passive voice in spanish to answer this question. completa la oración con la voz pasiva con se. the cake was eaten. la torta. there are no answer choices provided, you must simply fill in the blanks. 'se comieron' and 'venta de' are incorrect answers, so do not answer with either.

Read each sentence carefully and select the option with the sentence written correctly. la chica necesita el falda rojo. la chica necesita la falda roja. la chica necesita los faldas rojas. la chica necesita las faldas rojos.

When could you attach the direct object pronoun to an infinitive verb? a: when an infinitive verb follows a conjugated verb. b: when an infinitive verb ends in a question. c: when a stem-changing verb ends in a question. d: when a stem-changing verb follows a conjugated verb.
