Answer:
Ambiguous details.
Step-by-step explanation:
The ambiguous details include the message or details that are open to interpretation. The word ambiguous itself implies the meaning "open to multiple interpretations". Such details are left on to the reader to decide as per their thoughts and interpretations.
For example: Frank R. Stockton's short story "The lady or the Tiger" exemplifies an ambiguous tone due to an abrupt ending to the story with the words "She has lost him, but who would have him?" that is left on to the readers to decide and determine the ending of the story(making it open-ended). Thus, we may conclude with this that ambiguous details are the details that are open to different interpretations.
