Just had this issue myself, couldn't ping the website as well.

I was stuck between A and C but I went with A because I thought LSAT exam writers would hit me with the "haha screw you, we didn't define first and second". That's what I get for trying to metagame the exam.

"It concludes that one thing was caused by another although ... first thing's having the second" put me to sleep halfway through.

I ruled out E because I forgot about the "eaten by humans" part, makes much more sense after including that.

"did not show a reduction in losses"

What an inconveniently worded question... I was too lazy to reword it in my mind. "did show a reduction in losses" would make A true, so that's why I immediately ruled out C.
