Final answer:
The statement 'Are they the people who came from France?' is written in standard English.
Step-by-step explanation:
The statement 'Are they the people who came from France?' is written in standard English. The subject of the question is the identification of people who came from France. The sentence follows the structure of a standard English question, starting with the verb 'Are' followed by the subject 'they' and the question itself. The use of the definite article 'the' before 'people' is also correct.
