答案
参考答案：C
解析：
The median is the number that is numerically in the middle of a group. C is the answer because the sum of any three out of five numbers must be larger than the median, because even if it is the three smallest numbers, those numbers will include the median among them. You can confirm that all of the other options are possibilities if the variables equal 1, 2, 3, 4, 5.
