Answer: True
Explanation:
East Africa has diverse climatic conditions due to the different elevation and latitudes present. In East Africa, certain areas are very high such as in Ethiopia, Kenya and Tanzania with the latter two having two of Africa's tallest mountains.
This has caused a difference in climatic conditions with certain areas receiving a lot of rain and others not probably due to the effects of frontal rainfall.
Countries like Uganda, Tanzania, and western Kenya receive a lot of rainfall which allows for more woodlands as opposed to the arid vegetation of Somalia and parts of Kenya and Tanzania.
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.
The Bull Moose Party (also called the Progressive Party) was started by Theodore Roosevelt in 1912, just after the Republican Party has split up between Roosevelt and Howard Taft.
