Question

How do you judge whether a conclusion is successful?​

Answer 1

Depends on the paper

Step-by-step explanation:

I assume you are writing an essay so;

an argumentative/informational essay needs to address the thesis. The conclusion is basically a ”part two” to your introduction. To know if your essay is successful, you need to check/reread it and confirm that it appropriately addresses your main points or ideas.

Answer 2

A good conclusion restates the thesis word for word and adds one new fact.
