Question 31 - 40.
Read the following passage about powering the future and mark the letter A, B, C or D on your answer sheet to indicate the option that best fits each of the numbered blanks from 31 to 40.
As we continue to face the impacts of climate change, having a green environment has become increasingly important to the future of our society. To achieve this, the world is shifting towards green energy, and two particular types of energy at the centre of this movement are solar power and wind power.
[I] This highly efficient form of energy produces zero emissions, so it can significantly reduce our carbon footprint. [II] Moreover, solar panels are perfect for installation on a small scale, such as in private homes, since they require very little maintenance and have a long lifespan. [III] However, the ability to generate solar power depends on the time of day and weather conditions. This means that solar panels are often less useful if they are installed in places where sunny weather is not typical. [IV]
Wind power, on the other hand, involves converting the energy of the wind into electricity using large turbines. Wind power doesn't produce any greenhouse gases, but it is not ideal for private use since turbines require consistent care. However, wind farms can be installed on a large scale and are able to produce electricity continuously regardless of the time of day. This means that if there were more investments in wind power, it could be a viable way to provide energy for major cities and even for whole regions.
Wind and solar power contribute significantly to a green environment by reducing our reliance on fossil fuels, helping us cut down on pollution and slow climate change. Additionally, using renewable energy sources helps promote spending on sustainable development by creating new career opportunities in the green energy sector.
For now, the biggest challenge of adopting green energy is the costs associated with installation and infrastructure, but the benefits unquestionably outweigh the downsides. If we want to stop the climate crisis and create a better and more sustainable future, green energy sources will undoubtedly be the key.

The word “viable” in paragraph 3 is OPPOSITE in meaning to
possible
practicable
unworkable
feasible
Giải thích chi tiết
✅ Đáp án: C. unworkable
🔎 Lí do:
Xác định yêu cầu → Vocabulary – OPPOSITE meaning → cần hiểu nghĩa của “viable” trong ngữ cảnh rồi chọn từ trái nghĩa.
"it could be a viable way to provide energy for major cities" → có thể là một cách khả thi / có thể thực hiện được để cung cấp năng lượng.
💡 Nếu không hiểu nghĩa của “viable” thì phải suy luận thế nào?
Nhìn cụm "could be a ... way to provide energy" → đang nói về một giải pháp có thể áp dụng được.
Kết hợp với "for major cities" → phải là giải pháp thực tế, dùng được, không phải ý tưởng vô ích.
→ Vậy “viable” = khả thi / thực hiện được → trái nghĩa là không thể thực hiện được = C. unworkable.
🚨 Những đáp án còn lại thì sao? ❌ A. possible: Nghĩa là có thể xảy ra → cùng hướng nghĩa với “viable”. ❌ B. practicable: Nghĩa là có thể thực hiện được → đồng nghĩa với “viable”. ❌ D. feasible: Nghĩa là khả thi → gần nghĩa với “viable”.
