Pronouns - necessity/order

[lizaann]

Good afternoon. It has been a long time since I logged in and things have been going fairly well on Duolingo. I guessed the right answer to this question (Section 6, Unit 35) , however, I don't understand. I was sure that I had a handle on pronouns (necessity and order), but it looks to me as if there is one too many, here, although it must be right because there were two or three other questions with exactly the same construction. Can you please help me understand? I even tried Google Translate, where the pronoun situation is different.
