Stimulus Package comprises...

• A. The trainer's voice volume only.
• B. Rewards used during training.
• C. Gestures, body language, location of training.

Answer: (C)

A stimulus package is the bundle of signals that accompany the main cue you give the dog. It’s not just the spoken word, but everything the dog picks up at the moment you issue the signal. The strongest elements are the trainer’s nonverbal cues—gestures, body language, posture, and proximity—and the place or setup where you train. These cues together shape how the dog interprets the signal and decides what to do.

Why this option fits best: gestures and body language are direct signals the dog reads, and the location of training provides contextual information that can change how the cue is perceived. Taken together, they form the complete package the dog uses to understand and respond to the cue.

Why the other ideas aren’t the best fit: relying on voice volume alone is too narrow a cue to define the package since volume can vary and isn’t a reliable stand-alone signal. Rewards used during training are reinforcements, not part of the cue the dog uses to decide what behavior to perform. The physical environment is part of the context, but by itself it’s less specific than including the actual cues and the trainer’s nonverbal signals; the option that includes gestures, body language, and training location best captures the full signal the dog uses.
