I believe the answer is: Emotional wellness
Emotional wellness refers to the ability to approach one's life in a positive outlook regardless of the situations that they faced.
People with good emotional wellness do not necessarily feel happy all the time. But they have a strong capability in managing their negative emotions so it could only display minimum effect.
Answer:a.Naturalist
Explanation:
A naturalist believes that subjects or participants are able to show their original behavior if they are in their natural environment. A researcher would be more likely to get a true presentation of the participants behaviour if they observe them in their natural environment, if they are not aware that they are under observation. People act normal in normal situations but may alter their behaviour in situations when they know they are being watched.
A naturalist will carry those experiments or research that can't not be done in a lab such as this one of observing women in a shelter.
A. freshwater fishing.
my reasoning:
Inside the Middle East, most countries have large supplies of oil, (which helps make the countries rich as they are today because of oil demands), which takes out the options C & D. The Middle East, is located within the Sahara desert, and so can contribute to desert research (B) as well.
So A, is your most logical choice.
hope this helps
