Is a sentence ending with 誰だ but without か a question?


I found the following sentence in tangorin.com,

> 台所をこんなに散らかしたのは誰だ。

And it is translated as

> Who's responsible for this mess in the kitchen?

Is it really a question or just a statement? Do we always need to translate it
and end with a question mark (`?`)?




"誰" makes it a question. It's similar to "何処（どこ）", "どれ" or "何時（いつ）". For
example, "ここは何処だ。", "正しいのはどれだ。", "飯は何時だ。", all of them are questions. It may
be a rhetorical question but can't be a statement. So yes, you need "?".

In Enno Shioji's example, even when both parties know the answer, it's still
considered as a rhetorical question and it should be translated as such.




It can be a question, or a statement. E.g. consider

[code]

    A: ものがいっぱいありすぎて全然料理するスペースがないよ。  
    B: 台所をこんなに散らかしたのは誰だ。
    
[/code]

B can say this when both know it's A who littered the kitchen. It's also
spoken without the question intonation if it's used that way. When it's a
question, it's pronounced as a question.
