We can conclude that when rocks have streaks of different colors, the colors of the rocks are the same.
Explanation:
The colors of the rocks are inversely proportional to the streaks of colres they have. If two rocks have streaks of different colors it means that they will have equal colors. Likewise, if two rocks have streaks of different colors, it means that they will have the same colors. This is because the colors of the rocks depend exclusively on the absorption of the wavelengths that the minerals in the composition of the rocks may or may not absorb.
In this example, john's whistling is serving as a discriminative stimulus.
This procedure, studied by Ivan Pavlov, shows a stimulus ( in this case the action of John's whistling) and a response ( the cattle run to the food trough).
Pavlov studied it with dogs. He realised that when a trainer fed them, dogs salivated. So, he presented the dogs with a "stimulus" ( the sound of a metronome) and when he gave the dogs food. After a few repetitions, when the dog listened to the stimulus, it salivated.
