Example of Proper Usage
- 'Mark Zuckerberg' → 'Date of Birth' → '1984-05-14', citation: https://www.facebook.com/zuck/about_contact_and_basic_info 1. This citation points to an official page for Mark Zuckerberg (as further evidenced by Facebook's 'blue check' on the profile) that states Mark Zuckerberg's birthday.
Example of Improper Usage
- 'Apple' → 'Date of Birth' → '1976-04-01' is incorrect, as an entity with 'is a' → 'company' cannot have a date of birth.
