"What is the difference?""This furniture is different from ___"Athat B that one

furniture好像不可数的巴,就不可以用
ONE了

that泛指，that one特指

B. ONE代指“furniture.”This 和 That在这里是这个和那个的意思。翻译过来会明白些，就是“这个家具跟那个（家具）不一样。”

that已经指代了名词
例：that is a dog.不说that one is a dog.
原因在于前文已经涉及到了！

答案选that ----只能解释为， furniture是不可数，所以不用one。
