Of the 230 single-family homes built in City X last year, how many were occupied at the end of the year?
(1) Of all single-family homes in City X, 90 percent were occupied at the end of last year.(2) A total of 7,200 single-family homes in City X were occupied at the end of last year.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
题目分析：
（1） 占用单户住宅的比例没有给出，因此无法得到占用的具体数。不能解题。
（2） 同样是占用单户住宅的比例没有给出，无法得到占用的具体数值，不能解题。
因此，本题答案为（E），两个条件结合起来也不能解题，必须提供新数据。
毕出老师您能不能说得仔细点，说的不清楚，只是你懂了而已，如果让一个小学生看，不一定能看懂。
Of the 230 single-family homes built in City X last year, how many were occupied at the end of the year?
(1) Of all single-family homes in City X, 90 percent were occupied at the end of last year.所有住宅里面有90%被占用，不知道去年建造的有多少被占用；(2) A total of 7,200 single-family homes in City X were occupied at the end of last year.一共有7200个住宅被占用，不知道去年建造的有多少被占用。
这种文字游戏的数学题真是#￥%！@#
of the 230 vs of all/the total of
给出的条件都不能得知 到底有多少是占用的去年新建的那230户
230是去年建的 7200是所有的
(1) X市去年年底独户住宅入住率为90%;(2)X市去年年底独户住宅入住率为7200户。
在X市去年兴建的230幢独户住宅中，有多少在年底被占用?
of the 230 vs of all/the total of
读题陷阱：整体vs特指 概念
of the 230 vs of all/the total of
坑：Of the 230 single-family homes built in City X last year VS Of all single-family homes in City X
这一题考点在于读题。故意将整体概念和特指概念放在一起。进行迷惑。the 230 和total7200无法被直接联系上。
