Cause and Effect website reading and exercises Website

What I found useful in the website was the idea of being: ambiguous and vague.

In the website, they are both specified with these descriptions:

-A word or phrase is said to be ambiguous if it has at least two specific meanings that make sense in context.

-A word or phrase is said to be vague if its meaning is not clear in context.

This helped me realize when I am talking to a person, I can tell now whether or not they are being ambiguous or vague. People today always speak as if they know everything. And people that listen to them with little knowledge believe them.

But since I learned these concepts from the website, I am able to tell whether or not the person knows what he or she is talking about. And by doing so, I can tell what kind of person they are; if they are liars or they like to pretend they know everything etc.
