Hi! If we take a look at the first rule that consecutive articles cannot cover the same topic as each other and combine that with the fact that Q and S both cover nutrition, we see that Q and S cannot go immediately next to each other in our sequence here. Thus, there must at least be one spot in between Q and S (and R), which is why Q S J Y G R H cannot be a correct sequence here. Remember to capture the multi-linear aspect of this game by inserting an additional row for the article topics and double-check that there are no consecutive topics. Hope this helps!
