Question

the primary purpose of a prefix is... establish a words denotation determine a words part of speech create an antonym the affixes attach to it

Explanation:

A prefix is an affix added before a root word. Analyzing options:

• "Establish a word’s denotation" is incorrect as prefixes modify meaning (like "un-" in "unhappy") but don't solely establish denotation.
• "Determine a word’s part of speech" is wrong; prefixes don't change part of speech (e.g., "re-" in "rewrite" keeps it a verb).
• "Create an antonym" is a common function (e.g., "un-" in "unhappy" (opposite of "happy"), "dis-" in "disagree" (opposite of "agree")).
• The last option is incomplete and unclear. So the best choice is the one about creating an antonym.

Answer:

C. create an antonym (assuming the orange option is labeled C; if labels were A: green, B: blue, C: orange, D: light blue, then the answer is C. create an antonym)
