Correct Response: D. Making sure that the children are safe in this scenario is paramount. Advising them to continue walking quickly yet comfortably reduces the chances of them being injured by running to the other side. Running to other side of the street as quickly as they can (A) could result in the children tripping and being in the crosswalk as cars begin to pass through. Standing still in the crosswalk and waiting to see whether oncoming cars will stop and permit passage (B) would place the children in the path of the cars and be very dangerous. Turning around and returning quickly to the side of the street from which the children started (C) might also be dangerous since the return distance might be greater than that required to make it to the opposite side of the street.
