About Question-phrase + か
Often, the adverbial particle か is used in the middle of a sentence, in the same way that it is as a sentence ending particle. The main differences are as follows:
Adverbial Particle: 副助詞 - Highlights uncertain things '不確かであること'. This is the same か as in どこか 'somewhere'.
Sentence Ending Particle: 終助詞 - Highlights doubts and questions '疑問や質問'. This is a direct question.
In the case of the adverbial particle か and 'uncertain things', this will almost always be followed by a word that is seeking information about the uncertain thing.
As can be seen in these examples, sometimes the adverbial particle will appear by itself, and sometimes it will appear together with the sentence ending particle in the same sentence. However, due to the 'uncertainty' being displayed by the adverbial particle, the question marker at the end of the sentence is not required.
Caution
This か should not be preceded by だ (or です), this is why words like どこか and 誰か are not どこだか and 誰だか.
