5 . You never know how good your neighbors are until there’s an emergency.

It was after midnight when Clifford _________ to the sound of a noise next door. Outside, he saw that the house next to his was on fire, and there were three people _________. A mother with a teenager and a 5-year-old child were _________ for help inside the burning home. Unable to get down the stairs due to thick smoke and _________, the only way out of the big fire was through the window.
