In an argument, what does 'sufficient' evidence refer to?

Sufficient evidence in an argument refers to evidence that is robust and strong enough to convincingly support a particular claim. This type of evidence serves to validate the argument and may consist of facts, statistics, expert testimonials, or well-founded examples, which work together to bolster the credibility of the assertion being made. When constructing an argument, having sufficient evidence is crucial, as it demonstrates that the claim is not just a matter of opinion but is grounded in reliable and relevant data.

The other options do not accurately capture what 'sufficient' evidence entails, as they focus on aspects like opinions, informal information gathering, or humorous examples, which do not contribute meaningfully to the strength of an argument. Therefore, the emphasis is on the necessity of strong and credible support to make an argument persuasive.
