问题 No living thing could survive at a vent except tube worms. [br] When a new vent forms, tube worms congregate around it voluntarily.
选项 A、Y
B、N
C、NG
答案 C
解析 When a new vent forms，tube worms congregate around it voluntarily．根据关键词定位到第七段，原文这句话“Scientists also don’t know how tube worms and other organisms locate new vents．”以及“But scientists aren’t sure whether the larvae float aimlessly or purposely follow clues…”，可知科学家并不知道tube worms是如何寻找vent的，选NG。
