Final answer:
The 4th legal test, 'Adaptation of the Article', helps determine the distinction between real property and personal property based on the nature and use of the article.
Step-by-step explanation:
The 4th legal test, 'Adaptation of the Article', helps determine REAL (real property) versus PERS (personal property) by examining how an article is being used or adapted in a particular context.
For example, if an article is permanently attached to a piece of land, such as a building, it is considered a part of the real property. On the other hand, if the article is not permanently attached and can be easily moved, it is considered personal property.
The 4th legal test helps in distinguishing between real property and personal property based on the nature and use of the article.
