What Do You Know About The Hainan Gibbon

Explanation
The Hainan black-crested gibbon, also known as the Hainan gibbon, is found in Hainan Island. This island, located in southern China, is the only place where this critically endangered primate species can be found. The Hainan gibbon is endemic to Hainan Island, meaning it is found nowhere else in the world.

Explanation
The rarest and most vulnerable ones are located in China.

Explanation
The correct answer is 25. This suggests that there are 25 Hainan Gibbons in existence.

Explanation
Southeast Asia is the correct answer because it is the only option that encompasses multiple countries. Haiti, Japan, and Southeast China are specific locations, whereas Southeast Asia refers to a region that includes countries such as Thailand, Vietnam, Indonesia, and Malaysia. Therefore, it is more likely to be the correct answer as it provides a broader and more inclusive geographical area where "they" could live and be found.

Explanation
The given answer "Mammal" is correct because the Hainan gibbon is indeed a mammal. Mammals are a group of animals that are characterized by having mammary glands, giving birth to live young, and having hair or fur on their bodies. The Hainan gibbon, being an ape, falls under the category of mammals as it possesses all these characteristics. Additionally, the statement in the question that describes the Hainan gibbon as the world's rarest ape and rarest primate further supports the fact that it is a mammal.

Explanation
The numbers of this endangered species have plummeted over the past 50 years. This suggests that there has been a significant decline in the population of this species over the course of half a century. The term "plummeted" indicates a sharp and rapid decrease, further emphasizing the severity of the decline. This timeframe allows for a long enough period to observe and measure the decline, making it a plausible explanation for the given answer.

Explanation
The correct answer is "All of the above." This means that the animals mentioned in the question are mostly hunted by poachers for food, as well as for illegal trade activities such as selling them as pets or using their body parts for medicines.

Explanation
The correct answer is 2100. This suggests that the prediction for the extinction of the subject in question is expected to occur in the year 2100.

Explanation
To protect a very rare species on the brink of extinction, understanding their generic health is crucial. Generic health refers to the overall health and well-being of a species, including their genetic diversity, susceptibility to diseases, and ability to adapt to changing environments. By studying their generic health, scientists can identify potential threats to the species and develop conservation strategies to ensure their survival. This knowledge helps in implementing measures to protect and preserve the species, such as habitat restoration, disease prevention, and captive breeding programs.

Explanation
The study indicates that genetic diversity has decreased since the 19th century. This suggests that over time, the genetic variation within a population has been reduced. This decline could be due to various factors such as human activities, habitat destruction, climate change, or the spread of diseases. The specific reasons for the decline in genetic diversity would need further investigation.
