Question

prescriptions for patients in a large hospital

Explanation:

Unstructured data lacks a predefined format. Social media posts can include text, images, videos, emojis, etc., with no fixed structure. Prescriptions, bread ingredients, and dog - show breeds have more defined and structured formats (e.g., specific medical terms for prescriptions, a list format for ingredients, and a set of recognized dog breeds).
