问题如下：
Which of the following is most likely to have a high level of industry risk?选项：
A.Toll road B.Pest control services company C.Oil well drilling service company解释：
SolutionC is correct. An oil well drilling service company operates in a highly competitive industry, where demand is difficult to forecast and is very sensitive to macro risk. Industry risk is therefore likely to be high. The toll road and the pest control services company have recurring, predictable revenues with significant "moats" or barriers to competition.
不太理解这个选项，pest control比石油勘探也容易进入，竞争者容易增多，为什么industry risk不高? Industry risk是指行业容易分析的程度吗？
