问题如下：
The
Elmer fund’s management strategy is：
选项：
A.active
passive
blended
解释：
The fund is
managed assuming that the market is efficient, and investments are selected to
mimic an index. Compared with active strategies, passive strategies generally
have lower turnover and generate a higher percentage of long-term gains. An
index fund that replicates its benchmark can have minimal rebalancing.
题目里有selected，自行选择似乎也很像active？
但后一句，market is efficient，确实代表passive。
求解答。
