腻害，up

D就更好理解了，D说9500 years ago和人合葬的是野生猫科类动物，就从就从根本上weaken了这个conclusion。和人合葬的都是野猫，就更别谈是农业开始时期用于防老鼠的家猫。希望对你有帮助。

首先我们要先找出这段话的conclusion，即最后一句话“this shows that felines were domesticated around the time farming began,when...”. C说猫被驯养但不捉老鼠，这只能质疑conclusion的后半句，即“when they would have been useful in protecting stores of grain from mice” 无法weaken前半句中猫从农业开始的时期被圈养。

呵呵

哈哈

答案d 因为否认了“domesticated”和抓老鼠

c是有消弱 但是c不是“most seriously weaken”
