JY's extremely (and necessarily) long and informative video provides a complete explanation for why E is correct. Its under the necessary assumption lessons in the main syllabus. If that doesn't do it for you, don't worry too much just yet; do some easier NA questions to get a feel for what a necessary assumption really is and then come back to this one, which is quite difficult. It's also critical to have a solid understanding of what a sufficient assumption is as well, which will (SPOILER!) assist in ensuring you don't fall for one of the trap answer choices.
