I is important to understand the question before arriving at the answer. For example - someoe may ask me - "Is X a good investment"?
Before I arrive at the answer, I need to study X. I study the document for X and look for the key facts. I evaluate the facts and then come to my conclusion.
In giving my reply, I present the key facts and my conclusion.
It is important for the readers to go through my process of arriving at my conclusion. They have to check the facts and the reasoning. They can then form their own conclusion, which may or may not be the same as my conclusion.
By going through this process, they will learn how to approach a similar question in the future.
