Final answer:
Dani was unable to communicate how much pain she was in due to severe malnourishment and neglected development, which prevented her from responding to pain stimuli or using basic communication methods.
Step-by-step explanation:
Dani could not tell the doctors how much pain she was in because she lacked the basic means of communication and did not respond to stimuli that would typically cause pain. Due to severe malnourishment and neglected development, she could not vocalize her needs or understand simple gestures.
Unlike conventional symptoms that are subjective but can be expressed verbally or through gestures, Dani's inability to communicate made it impossible for her to articulate her pain level or any discomfort she might have been experiencing.
