问题如下：
Molly notes that SD&R generally uses actively managed portfolios designed to earn a return in excess of the benchmark portfolio. For clients interested in passive exposure to fixed-income instruments, SD&R offers two additional approaches.
Relative
to Approach 1 of gaining passive exposure, an advantage of Approach 2 is that
it:
选项：
A.minimizes tracking error.
B.requires less risk analysis.
C.is more appropriate for socially responsible investors.
解释：
Correct Answer: C
C is correct. Enhanced indexing is especially useful for investors who consider environmental, social, or other factors when selecting a fixed-income portfolio. Environmental, social, and corporate governance (ESG) investing, also called socially responsible investing, refers to the explicit inclusion or exclusion of some sectors, which is more appropriate for an enhanced index strategy relative to a full index replication strategy. In particular, Approach 2 may be customized to reflect client preferences.
1.A选项，approach 1虽然是pure index，但是都是一些政府债，如果想要复制的话，成本就会很高，那不是会增加tracking error吗，而如果是enhance 的话，我只需要抽样就要，cost相比之下没有那么高。
2，B完全不知道要怎么理解。
