Evolution is the process of development over history, meaning that change in diet is constant.

Which statement best analyzes the rebuttal?

It is effective because it creates emphasis by adding reasoning to the claim.
It is effective because it provides both empirical and logical supporting evidence.
It is ineffective because it does not address or acknowledge the counterclaim.
It is ineffective because it does not logically point out a flaw in the counterclaim.

Answer 1

It is ineffective because it does not address or acknowledge the counterclaim.

Explanation: the rebuttal simply asserts that diets change over time but doesn't respond to the counterclaim's specific evidence that humans have long eaten both meat and plants or explain why that historical diet doesn't undermine the original claim.
