I have a few Unity questions, very important, can you help me please?

1. Unity provides a full scale animation module within Unity. If there were no such module, how would you handle your animation needs ?

2. When would it make sense to design a GUI with screen space set as World Space ? Explain what this setting means and provide an example how it can be used?

3.There are many aspects of audio that makes it appealing. So consider the statement : "A game would be incomplete without some kind of audio , be it background music or sound effects." Do you agree with this statement ?Why / why not ? Explain.
