Final answer:
In a menagerie, one is most likely to find monkeys because it is a place for displaying exotic animals. Dolphins show the greatest social complexity due to their highly folded brains and complex social behaviors. Llamas did not originate in the Old World, unlike the other listed animals.
Step-by-step explanation:
Among the listed animals, a monkey is most likely to be found in a menagerie, which is a collection of captive animals, typically exotic, kept for display. To address another question, looking at the relationship between increased cortical folding and social complexity, researchers have found that animals with more folded brains tend to have more complex social structures. Based on this, among the given options (rabbits, dolphins, goats, elephants), a dolphin has the greatest social complexity due to its highly folded brain, sophisticated social behavior, and advanced communication skills. It is well documented that dolphins live in complex social groups and exhibit behaviors that reflect high cognitive functions. Finally, in regards to the question about which animals did not originate in the Old World, the answer is LLAMAS, as they are native to South America.
