Is this grammatically correct, *"Is David and Marina part of the passengers first name?" Somebody is asking about 2 persons' names. For example, Joseph David and Martha Marina. Should it be "Are David and Marina part of the passengers' first names?"
Are the passengers' first names "David" and "Marina"?
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
