A.
Portfolios affect risk less than returns.
B.
Portfolios affect risk more than returns.
C.
Portfolios affect risk and returns equally.
解释：
B is correct.
As illustrated in the reading, portfolios reduce risk more than they increase returns.
风险和收益不是正相关么？组合分散化风险，难道不影响收益么？不太理解，能否举个例子

没看懂，分散风险为什么不是more returns，less risk，作那么为什么不选A
这个应该看哪个图呢？
这道题没明白是什么意思 风险和收益应该是想等的啊
