Piaget’s pendulum task assesses children’s and adolescents’ ability to use to solve a problem with multiple solutions.
a. symbolic imagery
b. logic
c. scientific reasoning
d. tertiary circular reactions

c) Scientific reasoning

Explanation:

Piaget's pendulum task consists in determining which factor is most important in determining the speed of swing of the pendulum, given a set of strings and a set of weights.

Participants in this task had to consider the following factors:

To determine which factor was the key factor in determining the speed of swing, they have to use the experimental method (they need to vary one variable at a time)

This systematic approach is an indication that children and adolescents are thinking logically.

Thus, since they need to use an experimental method and a systematic approach we can conclude that the right answer is c) scientific reasoning.
