1. Q1. What is the primary difference in mutability between Python lists and tuples?
   • Lists are mutable, tuples are immutable.
   • Lists are immutable, tuples are mutable.
   • Both lists and tuples are mutable.
   • Both lists and tuples are immutable.
2. Q2. Which of the following methods can be used to add an element to the end of an existing list?
   • list.insert()
   • list.extend()
   • list.append()
   • list.add()
3. Q3. Given a tuple `t = (1, 2, 3)`, what will `t[1:3]` evaluate to?
   • (2, 3)
   • (1, 2)
   • (1, 3)
   • Error
4. Q4. Which of the following statements is true regarding nested lists and nested tuples?
   • A list can contain tuples, but a tuple cannot contain lists.
   • A tuple can contain lists, but a list cannot contain tuples.
   • Both lists and tuples can contain other lists and tuples.
   • Neither lists nor tuples can contain other complex data types.
5. Q5. Consider the code: `my_list = [5, 2, 8, 1, 9]`. What will `my_list.sort()` do to `my_list`?
   • Return a new sorted list.
