Answer:
The element that is missing from this evaluation is:
evaluation of evidence.
Step-by-step explanation:
The evaluation we are analyzing here compliments Goggin's argument. It says what the claim is - that every person of voting age should vote. It also states that Goggin argues people should register to vote, in case they haven't already. However, at no point does this evaluation discuss the evidence Goggin gives to support her claim. She thinks everyone should vote. Why is that? What happens when people do not vote? What proof does she have of that? Is that proof strong enough? None of those questions is answered. Therefore, the author of the evaluation fails to mention and discuss evidence.
