6. Water is currently the leading renewable energy source used by electric utilities to generate electric power. What role does this quotation play in the article?
Answer: D
It provides a key idea that will be discussed in the article.
The quotation emphasizes the significance of water as a leading renewable energy source, setting the stage for the discussion on harnessing ocean wave power as a viable method of electricity generation. It highlights a central theme of the article, which revolves around the potential of water resources in renewable energy production.
A) It provides a summary of the main points that will be developed in the article.
This option is incorrect because the quotation does not summarize the main points; rather, it introduces a specific focus on water as a renewable energy source. A summary would encompass the overall ideas presented in the article rather than just one element.
B) It provides a concrete example of a bigger idea the author will address.
While the quotation does relate to the broader topic of renewable energy, it does not serve merely as an example. Instead, it articulates a key idea that underpins the entire discussion about ocean wave power, making this option incorrect.
C) It provides a different way of examining a problem the author will discuss.
This option is not accurate, as the quotation does not introduce a different perspective on the problem but rather reinforces the significance of water resources in energy generation. The article primarily focuses on the benefits and challenges of ocean wave power, which this quotation supports rather than reexamines.
D) It provides a key idea that will be discussed in the article.
This option is correct because the quotation succinctly encapsulates the essence of the article, which revolves around the potential of water, specifically ocean waves, as a renewable energy source. It serves as a foundational concept for the exploration of the advantages and disadvantages of using ocean wave power.
Conclusion
The quotation plays a crucial role in framing the article's focus on renewable energy derived from water, specifically ocean waves. While the other options present interpretations that mischaracterize the function of the quotation, identifying it as a key idea accurately reflects its importance in guiding the reader through the upcoming discussions on ocean wave power and its implications for energy production.
