質問: 間接疑問について what has happened to her?これにdo you thinkを 挿入した文は what do you think has happened to her? らしいんですが、この形は疑問詞 do you think svなのでwhat do you think she has happened to?では ないんでしょうか?
回答: what do you think she has happened to? do you think を除いて、元の文章に戻すと what did she has happened to? この文章の、意味と文法はどうなるのでしょうか?
