In this task you need to press the key B if you see a letter H or O (small or large). You need to press the key N if you neither see a H nor an O. You can find for example groups of small s forming a large H, groups of small o forming a large L, or also groups of t forming a large T. Remember to press the key B when you see a H or an O (small or large), and to press the key N when you neither see a H nor an O. There are many combination of letters, you need to carefully check for H or O. You get feedback on every trial (correct, wrong or too slow). Once you get to the end, press the spacebar then click OK.
