Answer:
the licorice-flavored water.
Explanation:
From the experience of the rat and the study of adjunctive behavior, the rat would most likely identify the licorice flavored water as the reason why they became nauseous or they would think that the nauseous feeling comes after ingesting the licorice flavored water, hence they are most likely to avoid the licorice-flavored water, and instead go for the green water. Adjunctive behavior is an excessive behavioral pattern that becomes apparent as a result of an sporadic time-based schedule of reinforcement.
