The correct answer is the doll
Hypotheses, dependent and independent variables form a set of tools that help us to create theories about natural phenomena.
The process for investigating a particular phenomenon in nature usually involves three levels. In the first level, observation of facts, phenomena, behaviors and activities takes place; at the second level, we have the hypotheses and finally, at the third level, theories, valid and sustainable hypotheses (those that have been tested) arise.
Independent Variable:
these variables influence, affect or determine other variables.
it is a determining factor, condition or cause for a given result, effect or consequence.
it is the factor manipulated by the researcher in order to determine the relationship of the factor with the observed phenomenon, to see what influence it has on a possible result.

The correct answer to this open question is the following.
The adage most appropriate to memory function and aging is "use or lose it."
That is why it is so important to continually exercise the memory function so the brain never loses its ability to do something previously learned. You use it and you practice it so you master. Mastery is the result of constant repetition. So it is better to use something to be fresh in the memory and could be used when needing it.

Answer:
avoidance learning
Explanation:
According to my research on operant conditioning, I can say that based on the information provided within the question this scenario exemplifies avoidance learning. This term refers to the process in which an individual adapts a specific behavior or action in order to avoid a certain stressor or negative situation. This is the case in this scenario as the student decided to study a lot harder (specific behavior) in order to avoid the negative outcomes of bad grades in the future (negative situation).
