Question

economic models claim to be a(n)
reasonable abstraction of how people make choices, highlighting the most important factors.
exact replication of the decision - making process people use.
interesting chalkboard exercise with little applicability to the real world.
exceptionally accurate method of predicting nearly all behavior of everyone.
absolutely correct description of the world.

Explanation:

Economic models simplify real - world complexity. They don't exactly replicate decision - making (so option about exact replication is wrong), they are applicable to real - world (so option about little applicability is wrong), can't predict all behavior (so option about exceptionally accurate prediction is wrong), and aren't absolutely correct descriptions (so option about absolute correctness is wrong). They are reasonable abstractions that highlight key factors in people's choice - making.

Answer:

A. reasonable abstraction of how people make choices, highlighting the most important factors.
