本人的理解：
like在这里强行将owning and living in ...和that of earlier generations对称，是错误的。
题意应该是将 a goal of a majority of young adults与that of earlier generations对称。
如果改成like that of earlier generations, the goal of a majority of young adults is still owning and living in a freestanding house on its own land.就对称了
like要求前后必须是相同的事物
as 是连词，不要求前后是完全相同的事物ffice ffice" /> |
