Respuesta :
D, as extrinsic means external stimulus. Andrew may not necessarily enjoy doing extra math problems, but there is an incentive, which is good grades. With the other 3 people, there is no incentive other than enjoyment.
The correct answer is D.) Andrew wants a good grade in calculus, so he completes extra practice problems.
Explanation:
Extrinsic motivation refers to external factors such as money, grades or fame that motivate or make one individual behave in a specific way or complete certain tasks. For example, an extrinsic motivation for applying to a job is the wage or money related to it. This is the opposite of intrinsic motivation that includes factors such as satisfaction that are withing the individual.
According to this, the one that is an example of extrinsic motivation is "Andrew wants a good grade in calculus, so he completes extra practice problems" because in this case, the motivation or what makes Andrew complete extra practice problems is related to an external factor that in this case is a good grade.
