Of course to pass the challenge you need to remove both the elements:

states = [
    'ACTIVE',
    ['red', 'green', 'blue'],
    'CANCELLED',
    'FINISHED',
    5,
]
states.remove(5)
states.remove(['red', 'green', 'blue'])

The remove() function accept only one parameter as you can see here on the documentation.

https://docs.python.org/3/library/array.html?highlight=remove#array.array.remove

states = [
    'ACTIVE',
    ['red', 'green', 'blue'],
    'CANCELLED',
    'FINISHED',
    5
]
states.remove(5)

works as expected

When I try to copy your code it passes. Have you done each removal on a separate line? E.g

states.remove(5) states.remove(['red', 'green', 'blue'])

If so, it should pass.
