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.

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
