The existence of many different signs for words like PICNIC, BIRTHDAY, and SOON illustrates language variation in sign languages, and reflects the complexity and diversity of deaf culture and linguistic practices.
Step-by-step explanation:
The fact that there are many different signs for PICNIC, BIRTHDAY, and SOON is considered to be an example of language variation. This is observed across different sign languages and within regions of the same sign language, reflecting diversity in how communities communicate.

Variations in sign language exemplify the broader phenomenon of linguistic diversity that adds to the cultural tapestry of human societies.
The multiplicity of signs for terms like 'picnic', 'birthday', and 'soon' highlight the dynamic nature of sign languages and the way they adapt to the needs of their users.
