Answer:
2-year-old humans.
Explanation:
Dr. Nason and his colleagues have worked at teaching sign language to a great ape. Over the past year, they have observed the ape's slow vocabulary acquisition very closely. When their study is complete, Dr. Nason and his team are likely to find that the language acquisition of the ape is similar to that observed in:
a) pigeons
b) 4-year-old humans
c) African Grey parrots
d) 2-year-old humans.
This study will likely be similar to a two years old humans because ape possess the same basic syntactic and semantic capacities as 2-year old children and a two year old humans do not yet rely on spoken or signed language purely as their primary means of communication, they may be better suited for a comparison with nonhuman primate communication

<h3>
What is hierarchy?</h3>
A hierarchy is an arrangement of items (objects, names, values, categories, and so on). Hierarchy is a key concept in many disciplines, including architecture, philosophy, design, mathematics, computer science, organizational theory, systems theory, systematic biology, and social sciences.
A hierarchy can connect entities directly or indirectly, and it can connect entities vertically or diagonally. In a hierarchical system, the only direct links are to one's immediate superior or to one of one's subordinates, though a largely hierarchical system can also incorporate alternative hierarchies. Hierarchical links can extend "vertically" upwards or downwards by following a path with multiple links in the same direction.
