The final transcript and the bottom 'correct answer line' in the exercise still have '...qui émanaient de ce coin de m'ont accompagnéeS .....' instead of just "....m'ont accompagnée" - agreement with the speaker's gender.  The upper line 'best answer' indicated in the exercise is correct however. Cécile has answered a query on this previously. (I think I remember correctly what was presented in the exercise, but can't go back to recheck)

I must admit I often ignore 'agreement' like this when a text is in first person singular, and instead just use the 'agreement' that applies to me.
