Answer E

@Lucie Happy to help! Yes, (E) is correct because of the explanations provided in the preceding paragraph. That paragraph hypothesizes that tectonic plates moving in opposite directions/towards each other have shallow angles of descent and will experience more contact and therefore resistance. The last paragraph introduces a "warning" about regions with low levels of subduction and (E) connects this warning to the previous paragraph, thereby most logically completing the passage. Does that help? Let us know if you have any additional questions!
