Which hunger motivator depends on there being a large amount of food available?

• A. Palatability
• B. Quantity Available
• C. Presence of Others
• D. Variety

Answer: (B)

The main idea here is how external cues about how much food is around can influence how much we eat. When a large amount of food is available, people tend to eat more—a phenomenon known as the portion size or quantity available effect. That’s why this option is the best fit: it directly links hunger or eating behavior to the amount of food present.

Palatability is about how tasty food is, which can drive people to eat more, but it doesn’t require there to be a lot of food available. The presence of others can alter how much we eat due to social norms and modeling, not because of the quantity. Variety can also increase overall intake by offering more options, again not because there’s more food in the environment.

So the factor that hinges on there being a large amount of food available is the quantity available.
