Hello nicole, I solved your problem. The problem is with missing [] in the extend method. You can type something like this:

best = ['My','name','is']
new = ['Super','Man']
best.extend(new)

Or you can type simply this code:

best = ['My','name','is']
best.extend(['Super','Man'])

Why is task 1 is no longer passing i really don't know. Maybye the missing brackets in the extend method makes and error.
