Answer:
a well supported appeal to logic
Explanation:
For example, an argumentative essay. You would need good, strong evidence to back it up. If it isn't well-supported, your readers will not understand your logic in that argument. Another good example is a debate. When you watch a debate, you always hear their evidence that supports their argument. If their argument isn't well supported, then their debate wouldn't really make sense and sound weak compared to someone's argument that is well supported.
