  Remember, your assigned rank is: <b>{player.determined_rank}</b> (with A being the highest rank possible and H being
  the lowest rank possible). Your assigned rank was determined either by your performance or at random.

  <b>Do you think that your assigned rank was determined by the performance in the effort task, or rather at random?</b>
