Prompt: 
Given a list of receptacles, please sort them in descending order based on the likelihood of finding a soapbar in each of them. The list of receptacles is: ['cabinet 4', 'cabinet 3', 'cabinet 2', 'cabinet 1', 'countertop 1', 'garbagecan 1', 'handtowelholder 2', 'handtowelholder 1', 'sinkbasin 2', 'sinkbasin 1', 'toilet 1', 'toiletpaperhanger 1', 'towelholder 1']. You should directly return a Python list.

Act: go to drawer 1
Obs: The drawer 1 is open. In it, you see a butterknife 1, and a fork 1.
Act: go to sinkbasin 1
Obs: On the sinkbasin 1, you see a fork 3, a lettuce 3, and a spatula 2.
Act: clean knife 1 with sinkbasin 1

You have generated code of solution() to solve the task. However, you executed the solution() function and get an error message:
AssertionError: Error in [Step 4]: I cannot clean the knife 1 using the sinkbasin 1. The last three interactions before error were:
Act: go to drawer 1
Obs: The drawer 1 is open. In it, you see a butterknife 1, and a fork 1.
Act: go to sinkbasin 1
Obs: On the sinkbasin 1, you see a fork 3, a lettuce 3, and a spatula 2.
Act: clean knife 1 with sinkbasin 1

Prompt: 
Given a list of receptacles, please sort them in descending order based on the likelihood of finding a soapbar in each of them. The list of receptacles is: ['cabinet 4', 'cabinet 3', 'cabinet 2', 'cabinet 1', 'countertop 1', 'garbagecan 1', 'handtowelholder 2', 'handtowelholder 1', 'sinkbasin 2', 'sinkbasin 1', 'toilet 1', 'toiletpaperhanger 1', 'towelholder 1']. You should directly return a Python list.
