II. Some plastics are not caps.
III. No bottle is a cap.
A + I = No conclusion, hence conclusion I does not follow. Here, all the given statements are positive statements and both conclusion II and conclusion III are negative conclusion. As we know that no negative define conclusion can be drawn from the positive statement, we can say that neither conclusion II nor conclusion III follows.
