Question

Complete the sentence with the most appropriate answer.
Pontzer does not want the orang-utans to become extinct because ____________________.

• A. They are our closest relatives
• B. They are an endangered species
• C. A lot of information about our evolution will be lost
• D. He wishes to study them in the wild

Answer 1

Answer: (C)

A lot of information about our evolution will be lost

The passage gives information about the orang-utans who grow and reproduce slowly which makes them evolutionarily risky because the orang-utan may die before they can pass on their genes. ''Pontzer hopes the study will highlight how much information we will lose about our closest relatives and our own evolutionary history if we let them go extinct.'' which means that Orang-utans are the human's closest relative and their extinction will cause the loss of a lot of information about our evolution.

So, the correct option is C).
