According to a recent poll, owning and living in a freestanding house on its own land is still a goal of a majority of young adults, like that of earlier generations.
这一题不是强调owning and living in a freestanding house on its own land 对年轻人和对老一辈都是同一个东西吗?美国梦没变过,和generation无关。所以that作为new copy来说是错的,需要it。like放在句尾歧义很多啊,怎么也不是优选答案。
