Read this paragraph.

It's too soon to tell whether restrictions on human activity will have lasting impacts on wildlife, but some species have already benefited. One example comes from an April report on leatherback sea turtle populations in Thailand. With so many fewer tourists on the beaches, scientists have found a

larger number of turtle nests than in any year in the past 20 years. Leatherback sea turtles are endangered. They like to lay their eggs in a secluded spot, away from noise. These quiet spots are hard to find in the busy tourist season.

The details in paragraph 17 support the idea that –

• Fewer human activities have helped animal populations.

• More human activities have helped animal populations.

• Thailand has fewer leatherback turtles since the lockdowns.

• Thailand has caused leatherback turtles to become endangered.
