Sharing in case useful. I found it handy to RE-FRAME the conclusion.
"Therefore, this approach may in fact makes things worse rather than better".
"Therefore, this approach via reducing boat speed may in fact makes things worse because manatees can't hear low-pitched sounds from engines when they CAN today".
Answer choice E says that manatees can't discern sounds at any speeds. As a result, the conclusion does not make sense - they can't hear low pitched sounds nor high pitched sounds.
