练习15.34的答案是不是有些问题？

[SiberiaYaKing]

1.Query::Query(const std::string& s) where s == "fiery","bird" and "wind"
2.WordQuery::WordQuery(const std::string& s) where s == "fiery","bird" and "wind"
3.AndQuery::AndQuery(const Query& left, const Query& right);
4.BinaryQuery(const Query&l, const Query& r, std::string s);
5.Query::Query(std::shared_ptr<Query_base> query) 2times
6.OrQuery::OrQuery(const Query& left, const Query& right);
7.BinaryQuery(const Query&l, const Query& r, std::string s);
8.Query::Query(std::shared_ptr<Query_base> query) 2times

原答案如上 ，其中第5行与第8行不应该是2times把，后面15.39的答案都只输出了一次Query::Query(std::shared_ptr<Query_base> query)
