I have noticed that younger learners with the Read Aloud option have a hard time understanding that they need to go back and and pick an answer. They either listen to the first choice - see that the button popped up and assume they got it right and move on. OR they listen to all 4 choices - answer in their head - and move on leaving the last answer selected.

If the listen button could be unlinked from the multiple choice answers that would really help us get better data.
