1. In the first picture, the women are doing hard jobs , they are working on a hot day and the look on their faces is a sad one while the people in the second picture are studying ,helping each other , learning together and smiling.
2. Their lifestyles are so different because in the first picture life is very hard , unhappy with little resources , but in the second picture life is easy , they can have and get anything they want because they have a lot of opportunities.
3. Of course it is . When you have little food to feed your children and yourself , when there is no water and shelter, life is more stressful.
4. I would like to lead the second lifestyle because it is much more wasier to work in an agency than to do the hard works.
