What is reasoning? someone help me out

Reasoning is the action of thinking about something in a logical, sensible way.

It's often the influence of people's actions. Reasoning can be in your own thoughts, though reasoning may be more obvious. Example of Reasoning:

1- There is a door that leads into a room with fire, and there is a door that leads to the safe outdoors. They chose to go outdoors. Reasoning: The door outside is the safest, easiest option.

2- You have to complete cooking a dinner in 5 hours. You can begin making every course of the meal at once, or you can finish each one at a time. You choose to go step by step. Reasoning: You know doing it all at once will be too stressful, and it would be more efficient to finish each one at a set pace.

Hope this helps :)
