In this context, the word versions refers to different forms or adaptations of the story "Cinderella." To find a suitable synonym, we need to identify a word that conveys the idea of differing forms or kinds.
Let's analyze the options:
Problems: This word refers to issues or difficulties and does not relate to the concept of forms or adaptations.
Features: While this could refer to characteristics, it does not imply different forms of a story.
Variations: This word directly indicates different forms or adaptations of something, making it a strong candidate as a synonym for "versions."
Signals: This refers to indications or signs, which is unrelated to the idea of differing forms.
Thus, the most appropriate synonym for versions in this context is the one that conveys the idea of differing forms or adaptations.
