Answer: Physiological needs
Explanation: Given that these are children who did not have breakfast before arriving at school and who have difficulty focusing on what Tanya is teaching until after lunch, this is about physiological needs. When students are finally able to eat and become capable of normal student activities, which is normal follow-up, it means that they have met the basic physiological needs required for normal functioning. These are not any self-actualisation or, for example, safety needs, all these other needs come only after the physiological needs have been met, and those needs include also sleep, for example.
