Final answer:
A claim in argument writing should present the argument, be supported with reasoning and evidence, and include citations, but it should not make absolute statements.
Step-by-step explanation:
A claim in argument writing should include several key elements, but there is one aspect it does not necessarily need to have. A strong claim should present the argument, be supported with reasoning and evidence, include various forms of support such as facts and opinions, and provide citations for material from other sources. A claim does not have to make absolute statements or assertions that cannot be backed up with evidence. Therefore, claims in an argument do not need to prove something definitively without any room for debate or further discussion.
When writing a claim, it's essential to avoid making sweeping, absolute statements that can't be supported—such as "This proves that the government should...". Instead, a good claim is focused, manageable, and arguable, providing a base for presenting evidence and reasoning in support of your argument.
