Hey there!
We can assume her falling down the stairs was an accident and technically we can blame Ana for it. If not an accident, say that there was some water leaking from a pipe that went on the stairs or someone was cleaning them and left some hazardous slippery chemicals- that would be a violation of basic workplace standards.
However, our real problem here is Ron. He picks up Ana, and instead of calling someone who could help or seeing if someone else had a first aid kit, he uses a paper towel. The problem with this is that the cut could get infected because the paper towel may have bacteria on it. This is the main violation.
Hope this helps
        
             
        
        
        
Without adjectives, we could not describe things. Color would be less precious to us: there would be cars, but not red cars or blue cars or black cars. In describing a cat to someone who’s never owned a cat, all you could say is, “A cat is an animal with ears and a tail.” You couldn’t explain its soft fur or sharp claws.

<em>Billy Jo thinks that the sky is blue</em>. This is the independent clause. It has meaning by itself.
..<em>because the sun paints it each morning</em>. This is the dependent clause. It  does not have meaning by itself. It needs the independent clause. It gives extra information -reason-  related to the information in the independent clause.
