I was marked wrong before

Question

A couple of quizzes ago i was marked wrong for putting the object pronouns in front of the verbal structure. Unfortunately I can't get back to that quiz now to check, but I was sure they could go either before the whole verbal structure of be added onto the gerund/infinitive. The correction on my answer was to put the pronouns at the end of the infinitive/gerund.

Accepted Answer

Hola Francesca
I checked on your recent tests and I imagine you are referring to the question asking for how to say: "I'm taking it off". There were two possible correct answers for this:
1. Estoy quitándomelo 
2. Me lo estoy quitando
Both are correct. You ticked number 1 but didn't tick number 2, which is also correct. In multiple answer questions we say that there may be one or more correct answers. But you didn't get it wrong, you just ticked on one of them not the two. The system is just telling you that there is an extra correct answer for that question.
I hope this clarified it.
