单选题 On a scale that measures the intensity of a certain phenomenon, a reading of n+1 corresponds to an intensity that is 10 times the intensity corresponding to a reading of n. On that scale, the intensity corresponding to a reading of 8 is how many times as great as the intensity corresponding to a reading of 3?

【正确答案】 C
【答案解析】[解析] 由n+1所对应的强度是n的10倍可推知8所对应的强度是3所对应的强度的105倍，
