6. How would you evaluate the comments by Simpson’s supervisor about not using the IRR and about using the EAA? The supervisor is:
选项：
A.incorrect about both.
B.correct about IRR and incorrect about EAA.
C.incorrect about IRR and correct about EAA.
解释：
A is correct.
Both of the supervisor’s comments are incorrect. Because the Bayonne Pharma project is a conventional project (an outflow followed by inflows), the multiple IRR problem cannot occur. The EAA is preferred over the NPV when dealing with mutually exclusive projects with differing lives, a scenario which is not relevant for this decision. The Bayonne Pharma project is free-standing, so the NPV approach is appropriate.
conventional project是期初投资一笔现金流流出，期间都是现金流流入
那unconventional project是不是期初投资一笔现金流流出，之后可能是现金流流入，可能是现金流流出的情况？只有在这种情况下IRR是会产生很多问题的？
