Câu 1: Read the following passage and answer the question.
The red panda, a small arboreal mammal native to the eastern Himalayas and southwestern China, is classified as endangered. Its population is declining due to habitat loss and fragmentation, primarily caused by deforestation for timber and agricultural expansion. Poaching also poses a significant threat, with red pandas being hunted for their fur and as pets. Conservation efforts include habitat protection, anti-poaching initiatives, and community-based programs to promote sustainable forest management. However, the fragmented nature of their habitat makes connecting populations for genetic diversity a major challenge.

Câu 5: Read the following passage and answer the question.
The passenger pigeon, once the most abundant bird in North America, went extinct in the early 20th century. This rapid decline was a stark example of how human activity can devastate a species. The primary cause was overhunting on a massive scale, driven by commercial demand for pigeon meat and feathers. Their colonial nesting habits, where millions of birds nested in dense colonies, made them particularly vulnerable to hunters. Deforestation also played a role, destroying their habitat and food sources. The last known passenger pigeon, named Martha, died in captivity in 1914.
What made the passenger pigeon particularly vulnerable to overhunting?
- A. Their inability to fly long distances.
- B. Their habit of nesting in large, dense colonies.
- C. Their preference for living in open fields.
- D. Their slow reproductive rate.
Câu 6: According to the passage, besides overhunting, what other factor contributed to the extinction of the passenger pigeon?
- A. Loss of habitat due to deforestation.
- B. Competition from invasive species.
- C. A sudden outbreak of disease.
- D. Natural climate shifts.
Câu 7: The extinction of the passenger pigeon serves as an example of which broader concept related to biodiversity?
- A. The success of conservation efforts.
- B. The resilience of ecosystems.
- C. The natural cycle of extinction.
- D. The devastating impact of human activity on species.
Câu 8: Read the following passage and answer the question.

The concept of "keystone species" is important in ecology. A keystone species is an organism that helps hold the system together. If you remove a keystone species, the ecosystem could change drastically or even collapse. Their impact is disproportionately large relative to their abundance. Examples include sea otters in kelp forests, which control sea urchin populations that would otherwise overgraze the kelp, and wolves in Yellowstone, whose presence affects the behavior of prey animals and influences plant growth along rivers.

- A. They are the most numerous species in an ecosystem.
- B. They are always large predators.
- C. Their removal has a significant, disproportionate impact on the ecosystem.
- D. They are the first species to appear after a disturbance.
Câu 22: Based on the example of sea otters, how do they act as a keystone species in kelp forests?
- A. By preventing sea urchins from eating too much kelp.
- B. By directly helping the kelp grow faster.
- C. By serving as a food source for sea urchins.
- D. By cleaning the water around the kelp forests.
Câu 23: The passage suggests that removing a keystone species can lead to:
- A. An increase in the keystone species" prey.
- B. Minor changes in the ecosystem.
- C. The ecosystem becoming more stable.
- D. Significant changes or potential collapse of the ecosystem.
Câu 24: Read the following passage and answer the question.
The illegal wildlife trade is a multi-billion dollar industry that poses a major threat to countless species worldwide. It involves the poaching, smuggling, and sale of animals and plants, often for use in traditional medicine, as pets, for their fur or ivory, or as exotic food.

- C. Strengthening law enforcement and reducing consumer demand.
- D. Relocating endangered species to safer areas.
Câu 27: Read the following passage and answer the question.
Huge areas of rainforest are being cleared every day for cattle ranching, agriculture, and logging. This deforestation is a major driver of habitat loss, pushing countless species towards extinction. Rainforests are biodiversity hotspots, home to a vast number of unique plants and animals. Losing rainforests not only means losing species but also contributes to climate change, as trees absorb carbon dioxide. Efforts to slow deforestation involve promoting sustainable practices, enforcing laws against illegal logging, and creating economic alternatives for people living near forests.

- B. Encouraging more people to move into rainforest areas.
- C. Replacing rainforests with commercial tree plantations.
- D. Increasing the global demand for timber.
Câu 30: Read the following passage and answer the question.
Zoos and botanical gardens play a role in conservation, particularly through captive breeding programs and public education. For species facing imminent extinction in the wild, captive breeding can be a last resort to maintain a population. However, reintroducing captive-bred animals into the wild is challenging, requiring suitable habitat, minimizing threats, and ensuring the animals can survive independently. Zoos also educate millions of visitors annually about biodiversity loss and the importance of conservation, inspiring action and support.
