Answer:
A Conditioned stimulus.
Explanation:
'A Conditioned stimulus' is elucidated as the stimulus that was previously neutral eventually leads to evoke a learned response with training. Such a stimulus is contradictory to unconditioned or naturally occurring stimulus which triggers a specific response naturally while the former elicits a response through learning from the various factors.
As per the question, the 'opening of refrigerator' exemplifies a 'conditioned stimulus' as it evokes a learned response from the 'dog' as it runs to the kitchen every time 'refrigerator is opened'. Therefore, 'it demonstrates a conditioned stimulus' as Jasmine learns with time that 'every time the door is opened, he gets some food'.
I’m not sure what the question is. “Come” would be the correct present tense for the sentence, but if you need a different word with the same meaning to replace it with, then you can use “arrive” instead.
I hope this helped, if not, then you can reply specifying what the question is.
