* 1. Global - without context, `this` is in the context of either the Global or Window object

7+
* 4. Explicit - when using bind/apply/call, `this` context explicitly defined.
8+
"half stretch" answer to all 4: `this` generally refers to the parent context of where it's used.
9+
In the case of Explicit, the value of `this` is overridden to be what you give it.
