What will be the output of this program?
availableColors = ["red", "yellow", "blue"]
print(availableColors[2])
(1 point)
Responses
an error message
red
yellow
blue
The output of the program will be:
blue
This is because the code is accessing the element at index 2 in the list `availableColors` using the square brackets notation. In Python, indexing starts at 0, so `availableColors[2]` references the third element in the list, which is "blue".
What is the output of this program?
availableColors = ["red", "yellow", "blue"]
del availableColors[0]
print(availableColors[1])
(1 point)
Responses
red
yellow
blue
an error message
The output of the program will be:
blue
This is because the code deletes the element at index 0 using the `del` statement, which removes "red" from the list. After the deletion, the remaining elements in `availableColors` are "yellow" at index 0 and "blue" at index 1. Therefore, `print(availableColors[1])` will output "blue".
What is the output of this program?
availableColors = ["red", "yellow", "blue"]
availableColors.sort()
print(availableColors)
(1 point)
Responses
[“red”, “yellow”, “blue”]
an error message
[“blue”, “red”, “yellow”]
[“yellow”, “red”, “blue”]
The output of the program will be:
["blue", "red", "yellow"]
This is because the code `availableColors.sort()` sorts the elements in the list `availableColors` in ascending order. Therefore, when you print the list after sorting, it will display the sorted result: ["blue", "red", "yellow"].

availableColors = ["red", "yellow", "blue"]
availableColors.insert(1, "orange")
print(availableColors[2])
(1 point)
Responses
red
yellow
orange
blue
The output of the program will be:
orange
This is because the code `availableColors.insert(1, "orange")` inserts the string "orange" at index 1 in the list `availableColors`. After the insertion, the elements in `availableColors` are "red" at index 0, "orange" at index 1, "yellow" at index 2, and "blue" at index 3. Therefore, `print(availableColors[2])` will output "orange".
