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
The cilia and flagella of eukaryotic cells are composed of microtubules. (Option E)
Eukaryotic cells' cilia and flagella are made up of specially constructed microtubules.
Microtubules are nucleated cytoskeleton components. They are involved in various cellular functions as well as the maintenance of a cell's structure.
<h3>What is cilia and what does it do?</h3>
Cilia are hair-like structures found on the surface of all mammalian cells. They are rudimentary in nature and may be solitary or many. Cilia are important for movement.
They also participate in mechanoreception. Ciliated organisms are those that have cilia.

It was used to recognise the value of people (High and Low) and gave opportunities and respect to the high class people and not to the low class. Anyways, this was not a good idea as it discriminated people. In present India, caste system is not used as it causes Inequality.
Hope it Helped!
