问题如下：
An investor chooses to invest in a brownfield rather than a greenfield infrastructure project. The investor is most likely motivated by:
选项：
A. growth opportunities.
B. predictable cash flows.
C. higher expected returns.
解释：
B is correct.
A brownfield investment is an investment in an existing infrastructure asset, which is more likely to have a history of steady cash flows compared with that of a greenfield investment. Growth opportunities and returns are expected to be lower for brownfield investments, which are less risky than greenfield investments.
Brownfield是已经建成的成熟项目，此时稳定性好，现金流可预测，整体风险可控，B选项正确；同时对于brownfield项目一般比较稳定，通常不具备较高的增长性和高回报，所以A，C不正确。
知道greenfield风险更大，那会意味着收益比棕地更多吗？
