In that we're trying to look at how we can make decisions, the cost of particular proposals is normally an important consideration. We won't look at this here, but will meet it again later. Public opinion? Again, this is a criterion that's often very relevant. If we want to recommend one course of action rather than another, we might have to consider what public opinion is on the matter. In this case, for example, public opinion might favour putting the responsibility on parents to ensure that their children don't play unsuitable games rather than see the problem as one of banning games.

(D) What problems might there be for effectiveness because of practicability? How could this be enforced? What does 'encourage' mean? Look at (A). Encourage people to play violent computer games in the hope of reducing the chances of them being violent themselves.
