   2. B. fruits(0) = 'grape'
   3. C. fruits{'0'} = 'grape'
   4. D. set fruits[0] = grape
   5. E. fruits[1] = 'grape'

2. Tuple Characteristics

   Which statement best describes a tuple in Python compared to a list?

   1. A. A tuple is mutable and can be changed after creation.
   2. B. A tuple is immutable and does not allow item modification.
   3. C. A tuple only stores integers.
   4. D. A tuple uses curly braces for its definition.
   5. E. A tuple automatically sorts its elements.

3. Python Variable Assignment

   If you execute the code: a = 10; a = 'ten'; what will be the type and value of 'a' after both statements run?

   1. A. Integer, 10
   2. B. String, 'ten'
   3. C. Float, 10.0
   4. D. Boolean, False
   5. E. Tuple, (10, 'ten')

4. Identifying Correct Data Type Usage

   Suppose you want to store unique, unordered items in a variable. Which Python data type is MOST appropriate?

   1. A. list
   2. B. dict
   3. C. set
   4. D. tuple
   5. E. str

5. Interpreted Languages and Python

   Which statement accurately explains what it means for Python to be an interpreted language?

   1. A. Python code is always compiled directly into machine code.
   2. B. Python executes scripts line by line, making real-time debugging possible.
   3. C. Python requires all code to be written before running any part of it.
   4. D. Python cannot run on multiple operating systems.
