Answer:
Unimportant to a given topic.
Explanation:
According to the chart the prefix irr means not. Hence the "not" important ( relevant, the base of the word means important to a given topic)
When you act or behave a certain way purposely it's because you are motivated to act out that specific behavior so you already know what the results will be for your actions. This can cause awareness, because when you know what the result will be, that shows that you understand and are very much aware of your surroundings, which causes you to act that way purposely. This leads to more understanding. I hope that was good and makes sense.
