<span>Trees grow below or above the timberline, or tree line, depending on the environmental conditions present. Alpine tree lines are common near or on mountains and mountain ranges. The weather above the timberline is too cold and possibly too dry for trees to grow and take root. Desert tree lines are common in and near deserts. The soil is too dry for the trees to take root and get the water and nutrients they require. Desert-Alpine tree lines are environments where the elevation is too high and the soil too dry to foster tree growth.</span>
Answer:
The answer is b. and c.
Explanation:
With regards to answer b: A persuasive political speech is geared towards presenting an idea to the general population and supporting it with rhetorical argument. The politician uses rhetoric to garner support from the people, so the speaker has to use devices that appeal to the peoples general sentiments. For example, if a country is facing the decision of signing a free trade deal, the president might deliver a speech to persuade the people of the idea that free trade is the key to economic success.
With regards to answer c: the political speech might serve to unite people during a difficult time, such as wartime, and motivate them to act in the best interest of the country. Consider Winston Churchill, who led Britain to prosperity during World War II. He boosted the morale of the British people, and frequently travelled to the battle fronts to show his people that he new how to solve complex war situations and consequently take action. Since he consistently had 78% approval as prime minister, we can argue that his speeches united Britain and made them strive to take the best course of action.
John Garcia was an American psychologist very well-known for his researches that focused on taste aversion in rats and for discovering conditioning taste aversion. Taste aversion is often developed after having a drink or food that causes nausea, vomiting or sickness afterwards. Garcia challenged the idea that:
- any association can be learned equally well.
- conditioning takes place in an even faster and stronger manner when the conditioned stimulus is ecologically relevant.
Therefore, the ability to develop a taste aversion works as a survival mechanism. And, regardless of the taste of the food, sights and sounds, ones can tricky themselves into not liking the taste simply because they relate sickness with it.
