People seem to make this mistake quite often with regard to LSAT logic. The words "some" or "many" allow for the possibility of "all". For example, I might say "Some of the books in the library are fiction". The reality could be that every single book in the library is fiction, yet what I have said is still technically true. So, "animals of many species" allows for the possibility that they are speaking about every single animal. We can't assume that there are any that will not suffer damage, as likely as that may seem. Hope this explanation is clear.

That helps a bunch thank you. This LR section was very hard for me for some reason.

Don't sweat it. Everyone has a tough section now and then. Every time I'd hit a bumpy section, I'd just take a break for awhile, clear my head, and get right back at it. Never just keep drilling if you aren't maximizing what you are getting out of it. G'luck!
