问题如下：
4. Are Goldberg’s comments about real options correct?
选项：
A.No for Comment 1 and Comment 2.
B.No for Comment 1 and Yes for Comment 2.
C.Yes for Comment 1 and No for Comment 2.
解释：
B is correct.
Goldberg’s first comment is wrong. A project should be abandoned in the future only when its abandonment value is more than the discounted value of the remaining cash flows. Goldberg’s second comment is correct.
放弃期权不是期初支付一笔钱，未来如果项目需求低就可以行使放弃期权，后面的现金流就都是0了嘛。
解析当中出现的original investment 我认为可以相当于期权的成本其实也等于期权的价值了，因为后面没有现金流了。可以这么理解吗
