1. Your task is to write a function that finds the smallest number in a list of numbers. What is the best way to declare a temporary variable and why? a) Declare it as a local variable because it makes it easier to read the code.
b) Declare it as a local variable because using less memory is preferred.
c) Declare it as a global variable since it is easier to comment and faster to read.
d) Declare it as a global variable since these variables translate easier into machine code.

2. What type of variables are defined outside of a function?
a) Global
b) Inner
c) Local
d) Outer

3. Which of the following cannot be a variable name in Python?
a) addre55
b) Phone_123
c) userNAME
d) zip Code

4. When designing a program, it is good practice to find and reduce the amount of repetitive code. What is this practice called?
a) Code reduction
b) Deduplicating
c) Reducing repetition
d) Simplification

5. Explain how you would define a variable named balance, assuming that it will only be accessed in a single function.
a) Balance should be a global variable held in memory until the execution ends.
b) Balance should be a global variable on a hard drive to save memory.
c) Balance should be a local variable held in memory, so the code runs quickly.
d) Balance should be a local variable in the function, so it saves memory.
