TPO聽力 L1 Theater history 複選題 - 英檢

想請教第9題的複選題

9. According to the professor, what dramatic elements are typically
included in a well-made play to help move the plot forward?(2 answers)

A: A series of major changes in the hero's apparent chances of success
B: The introduction of new characters midway through the play
C: Information known to the audience but not to the main characters
D: The movement of major characters from one setting to another

正解給AC

不過我卻選了CD

想請問A代表的是key element裡面的哪一個?因為我認為D是inciting incident，
我把setting to another 解讀為劇情的推進，不知道是否有誤....

麻煩版上大大幫忙解惑一下


PS: 小馬這篇的聽力稿好多漏字或打錯的...Orz
