In order to better understand it, I'm afraid you will need to stop
thinking about multidimensional arrays, and start thinking of arrays
of arrays. First you need to get the inner array:

answer_choices[x]

then you get back an array. It's on this inner array where you want to
insert, so (split in two steps):

inner = answer_choices[x]
inner.insert(0, correct_ans_1)
