D. The shift will encourage farmers to adopt sustainable practices Read the following passage about renewable energy sources and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30. Renewable energy sources are those that can naturally replenish themselves over time such as solar, wind and Renewable hydroclectric power. Unlike fossi fuels, which take millions of years to form, renewable sources are constantly hydroelectric available and sustainable. As a result, they play a vital role in reducing pollution and greenhouse helping combat climate change . Wind turbines, for instance,produce energy without releasing carbon dioxide into the atmosphere, making them an environmentally friendly option. Despite these benefits,renewable energy sources still face challenges, For example solar power depends on sunny weather and may not produce energy consistently on cloudy days or at night. Similarly, wind power relies on specific wind speeds. If winds are too weak or too strong, turbines may stop working.This unpredictability often requires backup systems or energy storage solutions to ensure a stable supply of electricity. Many governments around the world are promoting the development of renewable energy through subsidies and incentives. In the United States, the federal government offers tax credits to homeowners who install solar panels. Meanwhile, Denmark has heavily invested in wind energy and now produces nearly half of its electricity from wind turbines Such initiatives help make renewable energy more accessible and affordable. Innovations in technology are further improving the efficiency of renewable energy sources.Advances in battery storage allow for the storage of excess solar or wind energy,which can be used when natural conditions are not ideal. In addition, new materials used in solar panels are increasing the amount of sunlight converted into electricity. These technological breakthroughs are making renewable energy a more viable alternative to traditional fossil fuels. Question 23: Which of the following is NOT mentioned as a renewable energy source?

## Answers and Explanations:**Question 23:*** **Correct Answer:** D. Nuclear* **Explanation:** The passage explicitly mentions solar, wind, and hydroelectric power as renewable energy sources. Nuclear power is not discussed, and it is not considered a renewable energy source.**Question 24:*** **Correct Answer:** B. restore* **Explanation:** The sentence states that renewable energy sources "can naturally replenish themselves over time." This means they can be restored or brought back to their original state.**Question 25:*** **Correct Answer:** C. renewable sources* **Explanation:** The sentence "As a result, they play a vital role in reducing pollution and greenhouse gases, helping combat climate change" refers back to the previous statement about renewable sources being constantly available and sustainable.**Question 26:*** **Correct Answer:** C. instability* **Explanation:** The sentence discusses the unpredictable nature of solar and wind power, which can lead to inconsistent energy production. "Instability" best captures this meaning.**Question 27:*** **Correct Answer:** B. Renewable energy sources may need support to provide consistent power.* **Explanation:** The underlined sentence states that the unpredictability of renewable energy sources often requires backup systems or energy storage solutions. This implies that renewable energy sources may need additional support to ensure a stable electricity supply.**Question 28:*** **Correct Answer:** C. The U.S. government supports solar panel installation with tax credits.* **Explanation:** The passage states that the U.S. government offers tax credits to homeowners who install solar panels. The other options are incorrect based on the information provided.**Question 29:*** **Correct Answer:** A. Paragraph 1* **Explanation:** Paragraph 1 establishes a cause-and-effect relationship between the availability of renewable energy sources and their role in reducing pollution and combating climate change.**Question 30:*** **Correct Answer:** D. Paragraph 4* **Explanation:** Paragraph 4 focuses on technological advancements in renewable energy, including battery storage and new materials for solar panels.
