Final answer:
The statement that a seagull came back for more food after being fed a cheese curl by a person is true given the opportunistic feeding habits of seagulls.
Step-by-step explanation:
The question presented appears to be related to the behavior of seagulls, specifically in response to human actions such as feeding.
Seagulls are known for their opportunistic feeding habits, often taking advantage of food provided by humans. In this context, if a student refers to a seagull coming back for more food after Greg throws a cheese curl out to it, it is true that the seagull would likely return, expecting more food.
This holds true with our general understanding of bird behavior, as observed in experiments where food access by birds can be influenced by various factors including the presence of humans and experimental conditions.
