问题如下：
Which of the following can be regarded as a continuous random variable?
选项：
A.The value of a futures contract quoted in increments of $0.05
B.The number of boys in a classroom
C.The stock return of a technology company over the next year
解释：
C is correct. The stock return of a technology company over the next year can not be precisely predicted, and the possible outcomes are infinite, so it can be seen as a continuous random variable.
其实还是没懂A选项？
