Question

door handle. once the door was open, she waited while stefon walked through, then followed him. uncle dwayne applauded as they came back in. “remarkable! i can’t believe you’ve only been training her for a few months.” stefon beamed. “i feel like marge and i have known each other forever.” he gave marge a treat and a fond ear rub. marge wagged her tail as if she knew exactly what stefon was feeling. stefon is training marge for the friendly paws service dog society. once she completed training, she’d be ready to work with a visually impaired person or someone else in need of assistance. “you’re going to ace that test,” stefon told marge. what is the most likely reason why stefon feels like he and marge have known each other forever? marge always wags her tail when stefon gives a command or comes into the room. stefon has been working so closely with marge that they communicate very well. stefon first started training marge when she was a puppy and he was a small boy. marge has learned a lot of amazing tricks, like opening and closing doors.

Explanation:

The text states Stefon has been training Marge for months, they work closely (he gives treats, rubs her ears, she responds to his cues and understands his feelings), leading to strong mutual understanding. The other options are either partial details or not supported by the text: the text doesn't say she was a puppy when he started as a small boy; tail wagging is one small interaction, not the core reason; door tricks are a skill, not the bond reason. The close work leading to good communication explains the "known forever" feeling.

Answer:

Stefon has been working so closely with Marge that they communicate very well.
