I think you should accept Edward Smith for the captain question. And also Thomas Andrews was the designer/architect of the ship technically, so those should be acceptable answers too. Oh, and for the question “Who owned the Titanic?”, could you please make it a bit clearer that you want the company, not the individual person. Because I tried J P Morgan and was confused as to who else it could be.
You could use a little more flexibility with your answers (i.e. accepting E J Smith or Smith for Captain Smith, but otherwise you did splendidly.
