Answer:
The correct one is the definition of <u>community psychology</u>.
Explanation:
Community psychology studies how the environment affects individual and community functioning, that is, how the interdependence and interaction of individuals and groups with social, historical, cultural (and other) contexts influence social health. The purpose of community psychology is to prevent dysfunction while promoting wellness, empowerment and social justice. As we can see, this is the same as saying, "Community psychology aims to create healthy social and physical environments." Therefore, the definition of community psychology is correct.
On the other hand, the definition "Health psychology investigates how people grow and change across the life span" is incorrect. Health psychology is basically the study of how psychological, biological, cultural, and behavioral aspects influence health and illness.

Answer:
Among the complaints about the Enlishmen that the author´s grandmother is:
- The habit of not taking a bath twice a day.
 - That they ate in front of each other.
 
Explanation:
Ethnocentrism is when people disagree with the culture of other countries, so they have prejudices against people who come from that country. Usually, ethnocentrism is a faithful defense of one's own culture without taking into account what others think; for these people, there are only their values.
For example, we can see that the author's grandmother does not agree that Englishman do not bathe twice a day, and just thinking that they can not bathe is inconceivable to her. All this is because she has other values, customs, and criteria different from the Englishmen but can not accept that it is good to have differences, and this is a clear example of ethnocentrism.
