Does anyone remember the last science question of the first passage? It asked something like which of the following causes less than 10% of all causes of extinction or something like that? I found that question really confusing because the lines on the graph were slightly higher than 10%, while some others were slightly lower than 10%. I remember getting the answer I&III only. What about you guys.
