What is scope? Your explanation should include the idea of global vs. block scope.

Scope describes where and when a variable can be accessed in code. 
Global scope is available anywhere in the code, whereas block is only available in a specific function or situation.


Why are global variables avoided?

Global variables can cause functions to be indeterminate, which means that they can have the same input and produce different results.
They can also cause code to behave in unexpected ways and make debugging difficult.
