Answer:
An analogy shows the relationship between two things at some point of similarity.
Explanation:
Amid a French campaign to South America in 1557, the wayfarer Villegaignon experienced a tribe of cannibals in what was then called "Antarctic France" yet what is presently called Brazil. Not basic, uninformed, and primitive as some would demand, cannibals, live in amicability with nature, utilize helpful and idealistic attitudes, and appreciate an impeccable religious life and legislative framework.
Often times, the actual object is much more expensive to create. That's why many designers and engineers create a model to represent their ideas to a group. The model is much cheaper and faster to create, especially if it needs tweaking multiple times. Also, that model can have working parts - you could take it apart to show the inside/cross-section or have interactive sections that allow easier presentation of your idea. Those are things you can't accomplish with an actual object.
