Answer: deception;debriefed
Explanation:
Deception during the research occurs when the participants are not given the fully information about the research that they are participating on or they are given the incorrect information about what the research is about .
This is usually done in order to receive bias free answers because when people know what the research is about they may sometimes answer in a way that will give a particular response that they feel is expected theirfore not being completely true.
A debriefing is now done to establish how people felt about the actual research or research question after they have already participated in a research in order to receive a feedback report . This is where everything in now explained to them properly and accurately.

The correct answer is a simulation.
Computer simulation of systems, or just simulation, consists of the use of certain mathematical techniques, used in computers, which allow to imitate the operation of, practically any type of operation or process in the real world, that is, it is the study of the behavior of real systems through the exercise of models.
There are several definitions for the simulation, among which we can quote Pegden (1990) who says “simulation is a process of designing a computational model of a real system and conducting experiments with this model in order to understand its behavior and / or evaluate strategies for its operation ”. In this way, we can understand simulation as a broad process that encompasses not only the construction of the model, but the entire experimental method that follows, seeking:
<u>
Describe the behavior of the system;
</u>
Build theories and hypotheses considering the observations made;
Use the model to predict future behavior, that is, the effects produced by changes in the system or methods used in its operation.
Answer:
No but those that live as travelling Traders are the Nomads
Explanation:
A nomad is an individual from a community without fixed home which routinely moves to and from similar territories. Such gatherings incorporate hunter-gatherers, pastoral nomads (owning livestock), and tinkers or trader nomads.
