问题如下：
What does the P/E ratio measure?
选项：
A.The"multiple"that the stock market places on a company’s EPS.
B.The relationship between dividends and market prices.
C.The earnings for one common share of stock.
解释：
A is correct.
The P/E ratio measures the "multiple" that the stock market places on a company’s EPS.
解析：P/E ratio是市盈率，分子是每股市价Price，分母是每股收益EPS，根据定义可以选出A。P/E ratio衡量的不是dividend和市价的关系，B错误，C说的是P/E ratio的分母。
EPS是P/Eratio的分母吗？
