Answer:
China's air pollution is a problem that they have to deal with. First, China has a great amount of carbon dioxide in one part of the atmosphere. For example, China has factories and other carbon dioxide producers that infect the air. They also have cars and people who release carbon dioxide. Second, China has affected other countries with the number of carbon emissions they have been producing. For example, China has affected countries as far as the U.S, which is 10,807.40 kilometers away from China. That means everyone under 10,807,40 kilometers from China will get affected by their carbon emissions. So, China has to fix their air pollution problem, or other countries and themselves will suffer because of pollution caused by carbon dioxide.
Hope this helps :)
The scenario demonstrates the phenomenon cocktail party effect. This is where a person can focus on a thing with the use of his or her auditory senses even when the person is on another stimuli. To simplify, it is where a person can still focus on the person he or she is talking to despite with the noisy background. This is what Lauren's is demonstrating as she can focus on the passenger even if there are multiple announcements.
We simplify using the properties given to us. But it is already done for us.
