A、Adviser. B、Accountant. C、Supervisor. D、Investor. A根据句(7)可知，杰克的工作是投资顾问，因此答案为[A]。

W: Oh, no, what’s the matter?
M: (6) I failed to audit the accounts properly. I was too careless to examine the data, and just input the figures my supervisor told me. I’m afraid it will cause great loss and I’ll have to hunt for another job. You see, it’s so difficult to find a position in such a recession.
W: Calm down. It’s not Doomsday.
M: I don’t know what I’m going to do! It’s going to be impossible to make ends meet if I lose my job!
W: Don’t worry. I don’t think you’re going to lose your job over just one mistake.
M: It was a rather big mistake. (7) When you work as an investment adviser, one small mistake can cost the company millions. It is reasonable for a boss to dismiss such an employee.
W: But it wasn’t just you who was involved, right? You were only doing what your supervisor told you to do.
M: (8) That’s true, but my supervisor is very dishonest. There’s no reason he needs to tell our boss the truth. I’m sure he will tell our boss that it was all my fault, and there’s nothing I can do about that. My boss won’t believe me if I tell him the truth. Anyway, not everyone is so lucky to have a good boss as yours.
W: If so, let’s think realistically about what might happen. How much money do you have in your savings?
M: (9) I have enough to live off for about 3 months. But I really don’t want to spend my life savings on just living! I’d rather invest my money somehow.
W: (10-1) Well, that’s good. If you lose your job, you can just move in with my brother until you find another job. That will save you plenty of money. I think he’ll be glad to help you.
M: (10-2) That’s very generous of you. I guess that would work.
W: If you lose your job, you just have to go for a few months without buying all the junk you usually buy. If you live frugally, you’ll save plenty of money.
M: I guess working with so much money has made me rather greedy. Maybe losing my job would be a good thing!
W: Well, maybe it will be a blessing in disguise.
M: I hope so.
