Please help me with below example and explain how to indentify quickly if simple tense past/present and passive voice.
- My clothes were scattered in my bedroom.
It means when I entered in my bedroom my clothes were in scattered state.
It means my clothes were scattered by someone
- Three people were killed.
It means three people were killed (maybe in an earthquake or a flood).
It means three people were killed by killer.
My question is whether the meaning of my sentences is that cloths were scattered by someone or just in the state of scatteredness when I entered the room. Clothes were maybe scattered by a cyclone or something.
