Final answer:
Morgiana against Cassim is not a conflict in the '40 Thieves' story; Morgiana helps her master against the thieves, while Cassim, Ali Baba's brother, is killed by the thieves. They do not have a direct conflict.
Step-by-step explanation:
No, Morgiana against Cassim is not a conflict in the '40 Thieves'. The story of '40 Thieves' is part of the collection of tales in 'One Thousand and One Nights', also known as 'Arabian Nights'.
In the tale, Morgiana is a clever slave girl who plays a pivotal role in saving her master, Ali Baba, from the forty thieves, and their leader is not named Cassim.
Cassim is Ali Baba’s brother who is killed by the thieves when he discovers their secret cave. Therefore, the conflict between Morgiana and Cassim does not exist in the tale since they do not have opposing goals or actions.
