Did a quiz, apparently answered wrong, and am now very confused.
The question: Elle ________ monté le poney de Jérémie et il a été très docile.
I went with "a monté". The quiz says the correct is "est monté".
Going by the Q&A, it seems like my answer was correct. I am stumped in two ways.
First, the Q&A says that avoir followed by the past participle is used for getting on a horse. This is a (pro)noun followed by a direct object. The lesson uses the example a "a monté mon cheval". I'm struggling to see why the verb auxiliary would switch based on who owns the horse.
Second, assuming I have the first part wrong someone how and être is the correct auxiliary, should the correct answer not be "est montée"? The subject is feminine.
