Question

Rochelle has a glass of Kool-Aid. She pours her Kool-Aid into a toy teacup, and then she pours the Kool-Aid from the teacup into a beer stein. She then pours it from the beer stein back into the original glass. She knows the amount of Kool-Aid has not substantially changed. What does this exemplify?

1) choices abstract
2) thinking abstraction
3) preoperational stage
4) reversibility

Answer 1

Answer: 4) Reversibility

Explanation: Reversibility is defined as the process in which the substance has the capability of returning to the same condition as it was originally .

The experiment done by Rochelle also describes about reversibility because the amount of Kool-aid drink won't change substantially when it return to the glass after being poured in different vessel. The amount of drink poured in all the vessel remain the same and it can get back to its original place(glass) .

Other options are incorrect because thinking abstraction removing facts while thinking, choice abstract is choosing thought that are non-existent current and prepositional stage is the stage in which preposition logic can be obtained .Thus, the correct option is option(4)
