For the first one it isn't A btw
Operant chamber is
laboratory apparatus consisted of the response lever, electrified grid and food dispenser.
Operant chamber (also known as Skinner’s box) is a
typical laboratory chamber (apparatus) in which the behavior and learning
process of rats was examined. This chamber is mostly empty, it has a food
dispenser, response lever which gives food when it’s pressed and sometimes
electrical greed. With this chamber, Skinner has learned in his research that
rats firstly press the lever by mistake, but that begins to happen more and
more. After some time, rats learn that when they press the lever they get food
as a reward. At the other experiment, rat have learned the same way that when
they press the lever, the electrified grid is turned off.
The correct answer to this open question is the following.
Superimposed boundaries caused ethnic conflict in the Belgian Congo, now present-day, Democratic Republic of Congo because people from the many tribes were forced to live with other people that had different cultural grounds and belief systems.
These superimposed boundaries in Congo force people to mix with other ethnicities and the experiment failed, causing upheaval and conflicts. People started to confront for different reasons: power, control, the use of limited raw materials and natural resources, political positions, and more.
The boundaries were imposed by European superpowers when they colonized this region and ignored the culture, history, customs, and traditions of the tribes.
