The following text is from a technology article.
Electric vehicles (EVs) are becoming increasingly popular, but charging infrastructure remains a challenge. Many potential buyers worry about running out of charge far from a charging station. However, new battery technologies are extending vehicle range, and governments are investing heavily in expanding charging networks. These developments are gradually addressing consumer concerns.
What is the primary purpose of the text?
To convince readers to purchase electric vehicles immediately
To explain the technical workings of EV batteries
To describe a challenge facing EVs and how it's being addressed
To compare electric vehicles to traditional gasoline cars
Correct Answer: C
Choice C is the best answer. The text identifies the charging infrastructure challenge, notes buyer concerns, and explains how technology and investment are addressing them.
- Evidence: The text notes "charging infrastructure remains a challenge" and buyers "worry." It then introduces "new battery technologies" and "governments are investing" to address this.
- Reasoning: The passage presents a problem and then describes the solutions being implemented.
- Conclusion: The purpose is to describe the challenge and its solutions.
💡 Strategy: Identify the problem (charging) and the response (technology/investment).
Choice A is incorrect because no purchase argument is made. Choice B is incorrect because battery technology details aren't explained. Choice D is incorrect because no comparison to gasoline cars is made.
