问题如下：
If you require an 8 percent return and must invest USD500,000, which of the investment opportunities in Exhibit 1 should you prefer?
选项：
A.Opportunity 1
B.Opportunity 2
C.Indifferent between the two opportunities.
解释：
Using cash flow additivity, compare the two opportunities by subtracting Opportunity 2 from Opportunity 1 yielding the following cash flows:
Finding the present value of the above cash flows at 8 percent discount rate shows that both investment opportunities have the same present value. Thus, the two opportunities are economically identical, and there is no clear preference for one over the other.
计算了IRR后，两个策略虽然差不多，但是还是有细微差别，如何知道这个是用现金流加和原则，还是看irr谁大谁小？这里不太明白怎么就知道用现金流加和原则？
