A

Answer to Question 2

An open system is one that accepts input. The logic of its internal workings can be understood and/or changed. It can change as a result of interaction with the outside world, and it produces output.
A closed system is the opposite of an open system. An open system takes input and produces output based on a logic that is comprehensible. A closed system has no definable input, output, and/or logic.
