Lists Practice Test

A sensor readings list of integers starts as 21, 22, 20, 23, 22. A technician checks one specific reading using an index, like looking up a time stamp in a log. The code prints readings3 using zero-based index. No readings are modified or removed. The list stays in the same order. Based on the scenario above, what is the output after executing the following list operation?

A song playlist list of strings starts as 'Blue','Gold','Neon','Pulse','River'. You remove one song by name, like deleting a track from a queue. The code runs playlist.remove('Neon') to delete that exact title. The remaining songs keep their current order. No other edits occur. In the context of the problem, how does the list change after removing the element?
