Question

semanticists are concerned with advertising because advertising often changes the ______.
○ meaning of words
○ context of words
○ size of words

Explanation:

Semantics is the study of meaning in language. Semanticists focus on the meaning of words. Advertising can manipulate or change the meaning of words (e.g., using euphemisms or redefining terms for persuasive purposes). The "context of words" is more about the surrounding text/situation, and "size of words" is irrelevant to semantics. So the correct option is about the meaning of words.

Answer:

A. meaning of words
