The following text is from a linguistics article.
Code-switching—alternating between languages within conversations—was once considered a deficiency. Researchers now understand it as a sophisticated skill requiring mastery of multiple linguistic systems. Bilinguals code-switch strategically, using different languages for emphasis, humor, or identity expression. This revised perspective has influenced educational approaches to multilingual students.
What is the main purpose of the text?
To provide instructions for learning multiple languages
To describe how understanding of code-switching has evolved
To compare bilingualism rates across different countries
To argue that monolingualism is disadvantageous
Correct Answer: B
Choice B is the best answer. The text describes the evolution from viewing code-switching as deficiency to recognizing it as sophisticated skill.
- Evidence: The text contrasts the past view ("once considered a deficiency") with the present view ("sophisticated skill"). It notes the impact: "influenced educational approaches."
- Reasoning: The passage focuses on how the understanding of this phenomenon has changed over time.
- Conclusion: The purpose is to describe this evolution.
💡 Strategy: Look for time markers: "once considered" vs. "Researchers now understand."
Choice A is incorrect because learning instructions aren't provided. Choice C is incorrect because countries aren't compared. Choice D is incorrect because monolingualism isn't criticized.
