fov里的一道无关因果

sm1916i

researchers havenotethat pandabears that have given birth to live young live longer in the wild. Therefore,these researchers have concluded that giving birth to live young increase a panda’s lifespan.
Q：the arguement smakes which of the following assumptions?
A: pandas that are already likely to live longer are also more likely to give birth to live young.

两件事同时发生不代表他们具有因果 这里Birth导致live long 我的assumption不应该是加强二者因果吗？可是answer里的答案是live long有更多babies不是反推了？这不是削弱原来的argument了吗？怎么会是assumption 我感觉我是在livelong 有更多babies的意思上没理解 是不能反推出来吗？QAQ
