1. What situations would be good to use context?
     When the data can be considered ‘global’, but it's not needed at intermediate levels.
2. If you need to pass a prop down 1 or 2 levels, is context necessary?
     No, context is useful when many components at various nested levels will need the data.
3. Can you pass a component instance as a prop to avoid the need for context?
     yes
4. Can you write your own components that accept render props?
     yes
