Answer 1

Both the Attwater’s prairie chicken and the passenger pigeon became extinct primarily due to changes made by humans to their environments.

- The **passenger pigeon** was driven to extinction in the early 20th century due to extensive hunting and habitat destruction. Once one of the most abundant bird species in North America, it saw its population rapidly decline due to commercial hunting and loss of nesting habitat.

- The **Attwater’s prairie chicken** is critically endangered and has suffered drastic population declines primarily due to habitat loss from agricultural expansion and land development, although it has not completely gone extinct.

The **whooping crane** and **American bison** are currently endangered but have not gone extinct. Efforts are ongoing to conserve their populations.

So the most accurate response would be the **passenger pigeon.**
