The following text discusses primate communication.
Vervet monkeys use distinct alarm calls for different predators. One call signals aerial threats like eagles, prompting monkeys to look up or descend from trees. Another call indicates ground predators like leopards, causing ascent to safety. These specific responses suggest the calls carry semantic content rather than simply expressing fear.
What is the main purpose of the text?
To argue that monkeys should be protected from predators
To compare communication abilities across primate species
To describe vervet alarm calls and their implications for language
To explain how to train monkeys to respond to commands
Correct Answer: C
Choice C is the best answer. The text describes the alarm calls and suggests they carry semantic content—implying relevance to language understanding.
- Evidence: The text describes calls: "One call signals aerial threats," "Another call indicates ground predators." It suggests implication: "suggest the calls carry semantic content."
- Reasoning: The passage uses specific animal behaviors to make a broader point about communication/language.
- Conclusion: The purpose is to describe calls and implications.
💡 Strategy: Summarize: The Calls (Eagle vs. Leopard) + The Meaning (Semantic content).
Choice A is incorrect because protection isn't advocated. Choice B is incorrect because only vervets are discussed in detail. Choice D is incorrect because training isn't addressed.
