【正确答案】 B

【答案解析】The multiple IRR problem occurs if a project has non-normal cash flows, that is, the sign of the net cash flows changes from negative to positive to negative, or vice versa. For the exam, a shortcut to look for is the project cash flows changing signs more than once. Only Project Blackjack has this cash flow pattern. The net cash flow in T2 for Project Keno and likely negative net present value (NPV) for Project Roulette would not necessarily result in multiple IRRs.
