Answer:
The phrase restates the underlined absolute modifier appropriately is the entirely opposite
Explanation:
Absolute modifiers are adjectives or adverbs that modify a noun or another adjective and have the full or absolute quality that is being represented either in its positive side or its negative side, then if the original sentence is "An economic recession is the most opposite side of prosperity" the phrase "most opposite" should be substituted by "the entirely opposite", leaving no space to have any improvement or advance.
