12. Correct the Paragraph
By the time Paul arrived at the house it is too late. The door was open, the light was on and his wife has disappeared. People are still walking home from work and the sidewalk in front of his house pulsed with a slow but steady stream of neighbors who stared at him as they passed. In the twilight the streetlamp’s glow casts dim and surreal highlights on the odd assortment of objects in his yard, the treadmill and the ten potted plants arranged in alphabetical order on the front walk. Looking back furtively over his shoulder as he folds the treadmill and secured its dangling electrical cord, Paul gives the impression of some agitation as he pushed the machine through the door and into the foyer of his home. One of the pots is an inch and a half out of alignment. Sighing, he nudged it into place and picked up a leaf that fell when the pot moved.
