Final answer:
Mean end analysis is a problem-solving strategy that helps break a problem down into sub-problems by thinking about the difference between an initial state and a goal state. It involves a forward search, where you start at the initial state and work towards the goal state. Option b) 'involves a forwards search only' is false.
