What can weaken an argument in a written response?

The presence of lack of concrete evidence and vague assertions fundamentally weakens an argument because it diminishes the persuasive power of the claims being made. An argument relies on clear, specific evidence to establish credibility and support its conclusions. When assertions are vague, they lack the specificity that would allow readers to understand and evaluate the argument effectively. Concrete evidence provides a solid foundation for the claims, making them more compelling and believable. Without it, the argument may appear unsubstantiated and may fail to convince the audience of the point being made.

In contrast, using complex language can sometimes enhance an argument by showcasing the writer's vocabulary and sophistication, though it risks confusing the audience if not done carefully. Overly detailed explanations can clarify points and reinforce arguments but may also sidetrack the main message if they become excessive. The presence of counterarguments can actually strengthen an argument by demonstrating that the writer has considered multiple perspectives, which can enhance credibility and depth.
