问题如下：
A report on long-term stock returns focused exclusively on all currently publicly traded firms in an industry is most likely susceptible to:
选项：
A.look-ahead bias.
B.survivorship bias.
C.intergenerational data mining.
解释：
B is correct.
A report that uses a current list of stocks does not account for firms that failed, merged, or otherwise disappeared from the public equity market in previous years. As a consequence, the report is biased. This type of bias is known as survivorship bias.
一份使用当前股票清单的报告，且没有包括那些因为失败、合并而退出市场的公司。
因此，该报告存在偏见。 这种类型的偏见被称为幸存者偏差。
请问这个考点是哪一章的reading中的
