Hey Jamie, it's a weird challenge isn't it?

Here's my solution to the challenge, instead of explicitly typing the list you want to remove, I just found the index in the list and removed it that way.

states = [
    'ACTIVE',
    ['red', 'green', 'blue'],
    'CANCELLED',
    'FINISHED',
    5,
]

states.remove(5)
states.remove(states[1])

This is also a clean way to do it. In a production setting, this would be more accurate. It ensures the list item itself is removed, and not just the values from the list, which in some situations could leave an empty list behind. Which we may or may not want.

Hola,

No worries, you are right and definitely on the right track. The only problem is the space. 

states.remove (['red', 'green', 'blue']) < ----- REMOVE the space between removes and the ().

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

Aside from that, you got it!
