What must a strong claim have to support it? Opinions, personal ideas, evidence or interesting topics?

A strong claim must have evidence to support it. While opinions, personal ideas, and interesting topics can help shape and articulate a claim, it is the evidence that ultimately adds credibility and validity. Evidence can include data, facts, examples, expert opinions, research findings, and logical reasoning. These support the claim by providing objective and verifiable information that substantiates it, making the argument more persuasive and compelling.
