Was the range of the amounts of money that Company Y budgeted for its projects last year equal to the range of the amounts of money that it budgeted for its projects this year?
(1) Both last year and this year, Company Y budgeted money for 12 projects and the least amount of money that it budgeted for a project was $400.
(2) Both last year and this year, the average (arithmetic mean) amount of money that Company Y budgeted per project was $2,000.
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）条件1给出了去年和今年预算的最小值，但并没有给出最大值，无法求得去年和今年预算的范围。
（2）条件2给出了去年和今年预算的平均值，无法根据平均值得到预算的最小值和最大值，也就无法求得预算的范围。
结合条件1和条件2，条件1只能得到最小值，但根据条件2也无法得到预算的最大值，除了最 小值以外，其余的值有多种情况使其平均值为2000美元，所以，无法得到预算的范围。
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。
坑： 问的是range of the amounts，不是total amounts
题目问的是range
mark， the range of the amounts of money 重点词是range，其他几个project有多重可能，造成range无法确定
坑+1： 问的是range of the amounts，不是total amounts
放进错题小本本，审清楚题目！！！
mark，project数量给了提示，12个project平均值是2000，就算得知最小值为400，剩下11个也有多种可能
mark
问的是range，就是能否确定最大值和最小值。问的不是total amount.
坑：range of the amounts
审题审题审题~ 问的是range of the amounts，不是total amounts
这种题在考场估计很难做对。
