• Primates are an endangered species.

• Primates share unique physical traits and behaviors that set them apart from other mammals.

• The main difference between prosimians and anthropoids.

• The history of primates and how they evolved.

How does the author support the central idea about what makes primates unique?

• By describing their ability to swing from tree branches and the structure of their shoulder.

• By discussing the different environments in which primates live.

• By focusing on the different diets of primates.

• By describing how primates communicate with one another.

Which of the following best explains how the author develops the idea of primates having special physical traits?

• The author focuses on the development of primates' social structures.

• The author compares primates to other animals with similar physical traits.

• The author describes how primates use tools to gather food.

• The author explains how primates’ unique traits, like flexible arms and opposable thumbs, help them survive in the wild.

What is the significance of the mention of the "collarbone" in the second paragraph?

• It highlights how humans are more evolved than other animals.

• It explains the importance of shoulder flexibility in all mammals.

• It shows a similarity between humans and other primates in terms of physical structure.

• It describes how humans and animals use their shoulders differently.

Which statement from the passage best supports the idea that primates are well-adapted for life in the trees?

• The collarbone lets you and other primates do something most mammals can’t: hang by your arms.

• Many primates, especially those that are diurnal, or active during the day, live in social groups.

• Primates have a large brain in relation to body size.

• Primates have flexible arms and legs.

What role do primate thumbs play in their development?

• They help primates climb trees faster than other animals.

• They give primates the ability to hold and use small objects, aiding in tool use.

• They allow primates to communicate with other animals.

• They help primates navigate through forests.

How does the author emphasize the importance of primate conservation?

• By explaining how primates are the most intelligent mammals.

• By listing the many uses of primates in human society.

• By showing that a significant portion of primates are critically endangered due to habitat loss.

According to the passage, which of the following is a primary difference between prosimians and anthropoids?

• Prosimians are larger and have complex social structures.

• Anthropoids have more species and are characterized by flat faces and keen color vision.

• Prosimians are known for their ability to use tools, while anthropoids cannot.

• Anthropoids are primarily nocturnal, while prosimians are diurnal.

What does the mention of Madagascar's disappearing forests contribute to the passage?

• It highlights the efforts of researchers to save endangered primates.

• It illustrates the benefits of maintaining tropical forests for all species.

• It explains why some primates are thriving in their environments.

• It shows how deforestation directly threatens the habitats of unique primate species like lemurs.

What can be inferred about the relationship between humans and primates based on this passage?

• Humans and primates share many physical and behavioral traits, indicating a close evolutionary relationship.

• Humans are the only primates that have evolved intelligence.

• Primates are not important to the survival of the ecosystem.

• Humans and primates are entirely separate in terms of physical characteristics.
