B．preference of their screenwriters C．consultation with the original author D．investigation into successful films
解析：选A 根据文章第六段第一句和第二句“ ... but there's still a difference between her and a megacorporation like Disney.”“Every character and beast is there because Rowling said so, not because the marketing division thought it would promote sales of merchandise.”可知像Disney这样的公司他们的喜好和J.K.Rowling不一样。J.K. Rowling塑造人物并不是考虑商业销售情况，那么像Disney这样的大公司考虑的是电影的潜在盈利能力。
14．How does the author explain Rowling's failure to create a clear plot? A．By describing shooting processes. B．By listing official statistics. C．By drawing a comparison. D．By citing examples.
解析：选C 推理判断题。根据文章倒数第二段的内容可知作者通过比较Harry Potte和The Fantastic Beasts系列，指出没有经验丰富的剧作家在她的想象力和银屏之间做调停，The Fantastic Beasts系列剧的故事情节并不是太清晰的。
15．What does the author think of J．K.Rowling's performance as a screenwriter? A．It is really a disappointment for movie goers. B．It is widely acknowledged by her book fans. C．There exits much more magic in her screenplay. D．There is still much room for improvement.
解析：选D 推理判断题。根据第一段的第二句“‘Fantastic Beasts: The Crimes of
Grindelwald’， shows that even the most successful author in the world is in need
of checks and balances when making the transition to cinema.”可知作者认为J.K.Rowling要从一个小说家转变成一个剧作家还需要历练。
