Real IELTS Sample Questions and Model Responses

Sample Question 1: Basic vs Applied Research Priority

Question: "Government research funding is limited. Some argue it should focus on basic scientific research to expand knowledge, while others believe applied research addressing specific problems is more important. Discuss both views and give your opinion."

Model Response Structure:

Introduction: Scientific research funding allocation represents one of the most strategic decisions affecting national innovation capacity and societal development. While basic research advocates emphasize fundamental knowledge expansion and long-term discovery potential, applied research proponents highlight immediate problem-solving capabilities and practical benefits. This essay examines both perspectives before arguing that balanced approaches integrating basic and applied research strategies provide optimal outcomes for comprehensive scientific advancement.

Body Paragraph 1 (Basic Research Priority Perspective): Basic research advocates present compelling evidence that fundamental scientific investigation creates the knowledge foundation necessary for all technological advancement while generating unexpected breakthroughs with revolutionary applications. CERN's Large Hadron Collider exemplifies basic research value, as fundamental particle physics investigations have produced numerous technological innovations including medical imaging systems, advanced materials, and data management technologies worth billions in commercial applications. Basic research also establishes scientific methodology and analytical frameworks that enable future discoveries across all fields. Furthermore, pure research universities attract international talent and investment, creating innovation ecosystems that strengthen national competitiveness while fostering scientific culture and evidence-based thinking throughout society.

Body Paragraph 2 (Applied Research Priority Perspective): However, applied research advocates highlight practical problem-solving capabilities and measurable social benefits that justify immediate resource allocation to targeted investigations addressing specific challenges. COVID-19 vaccine development demonstrates applied research effectiveness, with multiple vaccines developed within one year using existing scientific knowledge and focused research to address a specific global health crisis. Applied research produces faster returns on investment through commercially viable products and services while directly improving health, safety, and quality of life. Additionally, problem-focused research ensures that scientific resources address pressing societal needs including environmental challenges, disease treatment, and technological solutions that create employment and industrial competitiveness.

Conclusion: While both basic and applied research offer essential contributions to scientific progress, I believe that integrated approaches combining foundational research with targeted application provide optimal scientific advancement. Countries like Germany successfully balance basic research excellence with applied innovation, achieving both scientific leadership and economic competitiveness through coordinated research strategies.

Sample Question 2: Science Education Approaches

Question: "Some believe science education should focus on teaching established scientific facts and theories, while others argue students learn better through hands-on experimentation and inquiry. Discuss both views and give your opinion."
