On the left picture, there is a group of two teenagers and a woman working . They are manipulating wood so we can guess that they are carpenters .They may be constructing a house.They may be poor and so, do that to earn a living.
On the other picture, there are students( two girls) who are being thought by a teacher .They seem joyful .It may be a school .
I think the message passed behind these two pictures is to show discrimination and poverty in some countries. Some have the right to education while other don't .
