Final answer:
In the story of Cinderella, not everyone gets to try on the glass slipper; only various women, like the stepsisters, have the opportunity until Cinderella herself tries it on and it fits perfectly.
Step-by-step explanation:
The question "Did everyone truly try on the slipper?" refers to the story of Cinderella, which is a classic fairy tale found in many variations across different cultures. The answer to this question is dependent on the version of the story being referred to. In the popular version by French author Charles Perrault, and in many adaptations including the Disney animated film, not everyone gets a chance to try on the slipper. Instead, it is generally depicted that the slipper is tried on by various women throughout the kingdom, but due to the magical nature of the story, only Cinderella's foot fits perfectly. Therefore, the correct answer is not No, as specifically Cinderella's stepsisters and other women attempt to try on the slipper, but not literally every woman in the kingdom.
