Did Insurance Company K have more than $300 million in total net profits last year?
(1) Last year Company K paid out $0.95 in claims for every dollar of premiums collected.
(2) Last year Company K earned a total of $150 million in profits from the investment of accumulated surplus premiums from previous years.
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：
问公司K去年是否有超过3亿美元的净利润。条件（1）和（2）给出了收取保费和支付索赔的利润以及累计盈余溢价投资产生的利润，但不能得知是否有其他收入来源或其他类型的费用。因此，不能计算净利润。
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。
做错了选了b。个人理解。如果按照答案理解：（2）的说法错的原因是它并没有说出k公司去年total net profit。而是玩了一个文字游戏，说的是投资和premium的total profit。文中并未说“投资和premium就是k公司的total net profit”。这是个人理解，不知道对不对？
