Answer :
The least effective thesis example in addressing the prompt "Should Americans Be Required to Vote?" is:
(D) They don't have to vote if they don't want to for three reasons, most of which I remember.
Explanation:
1. This thesis example is least effective because it lacks specific reasons or arguments to support the stance against compulsory voting.
2. It is vague and does not provide any substantial information or logical reasoning to address the prompt.
3. The use of "most of which I remember" indicates a lack of concrete evidence or clear points to make a convincing argument against mandatory voting.
4. A strong thesis should clearly outline reasons or arguments to support the position taken on the issue of compulsory voting, which this example fails to do.
