Like the thorny ballooning of a frightened pufferfish or the sudden appearance of angry sapphire hoops for which the blue-ringed octopus is named, so the California newt's display of its red underbelly is a clear warning that predators ignore at their peril.
so the California newt's display of its red underbelly is a clear warning that predators ignore at their peril
so it is at their peril that predators ignore the California newt's display of its red underbelly, a clear warning
the California newt's displaying its red underbelly is a clear warning for predators, so they ignore it at their peril
the California newt's display of its red underbelly is a clear warning that predators ignore at their peril
it is at their peril that predators ignore the California newt's display of its red underbelly, a clear warning
……is a clear warning that predators ignore at their peril.警告那些捕食者，你们忽视了（靠近我的）危险性
is a clear warning for predators, so they ignore it at their peril，是一个给捕食者的警告，（那些捕食者看到这个警告后）就会忽视他们所处的危险境地
这里是加州newt发出这个警告，警告的目的是吓走捕食者，至于捕食者是不是真的被吓走了，我们并不知道，所以不能用so，用同位语解释说明警告的内容。
d中关键词of，与c比
并列
display》displaying
D,the ballooning VS the display, complex gerund平行于action noun，balloon的动名词只有ing形式，有些动词没有专门的动名词，只能用complex gerund来表示其名词形式或动作的结果。
cd之间选错了
display显示的名词形式，有动作的名词+of形式，就不要选动词ing形式， 所以“the California newt's display of”是优于c的
c用so也怪怪的
C错在so 从句，并没有因果关系
there's also the notion that
possessive + verbING + object
isn't correct, and that the correct version is
possessive + verbING + OF + object
C 和D怎么选？？
at their peril 自担风险
