Answer:
First-hand ethnographic fieldwork
Explanation:
Ethnography is the detailed account of a society and its culture by observing the social interactions that people have. This gives us an accurate description of a society and its culture as it not influenced by outside factors.
Here, Maria is studying the the lives of women in coffee farming communities in Brazil. She is observing them directly and making sure her presence does not influence their interactions. She is also doing this herself which means her research will not be affected by someone else's perspective.
Hence, she is using the strategy of first-hand ethnographic fieldwork.
The answer is: Social class
Social class is generally divided based on how much resources that those people have to influence a change in the society where they lived in.
In almost all modern societies, social class will clearly distinguished by the wealth/money that people possessed. So the society is divided into two, the poor and the rich.
People who had vast amount of wealth, could have larger influence in changing the society because they can funded their activism group or influence the legislation by giving funding to the government representative of their choosing.
Venus is unusual because it spins the opposite direction of Earth and most other planets. And its rotation is very slow. It takes about 243 Earth days to spin around just once. Because it's so close to the sun, a year goes by fast.
Personally, I believe that differing political views result in greater political participation because of a persons need to help the side they support win. Take this for example: Republican and democratic parties have come to an issue where they see two completely different solutions. The republicans are scared that if they don't have great amounts of participation, the democrats will win and the democrats are scared of they don't have great amounts of participation, the republicans will win. This need to help the idea they support win drives a greater amount of political participation form both sides and is applicable to any differing political views. Hope this helps! :)
