    Looks to be a complicated way of returning the index of the given matching element.
    The code assigns a variable (var) named questionNumber - this variable looks for the containing object's ($(this)) parents, finds number 3 (.eq(2) <- zero-based indexing) and returns that items index() - I'm a little unsure as to what this is supposed to do.
    Have a look here:
    https://api.jquery.com/eq/ regarding .eq()
    and here:
    http://api.jquery.com/index/
    regarding .index()
