A student is writing an argumentative essay about the benefits of renewable energy and has included the following sentence:
It's a total no-brainer that we should switch to solar power as soon as possible.
Which of the following revisions best replaces the sentence to maintain a formal and persuasive tone appropriate for the essay?
- The immediate transition to solar power represents a logical and beneficial step for energy policy. (correct answer)
- It's obviously a great idea for everyone to get on the solar bandwagon before it's too late.
- Only those who ignore scientific facts would dispute the incredible power of the sun for our energy needs.
- We haven't yet seen a better option than solar power, so we should probably go with it.
Explanation: When you encounter questions about tone and formality in argumentative writing, you need to evaluate how well each option maintains academic credibility while making a persuasive point. The original sentence uses casual language like "total no-brainer" that undermines the essay's authority. Choice A works best because it presents the argument using formal, academic language while maintaining persuasive force. Words like "represents," "logical," and "beneficial" convey professionalism, and the phrase "logical and beneficial step" makes a clear argument without relying on informal expressions or emotional manipulation. Choice B fails because it maintains the casual tone problem with "obviously" and uses the colloquial phrase "get on the solar bandwagon," which sounds more like casual conversation than academic writing. Choice C creates a different problem by using an accusatory tone ("Only those who ignore scientific facts would dispute") that comes across as hostile rather than persuasive—effective arguments convince through evidence, not by insulting opposing viewpoints. Choice D undermines the argument's strength with tentative language like "probably" and "we haven't yet seen a better option," making the writer sound uncertain rather than confident in their position. For GED argumentative writing questions, remember that formal tone means avoiding slang, casual expressions, and overly emotional language while still maintaining your persuasive intent. Look for options that sound like they belong in an academic paper—professional vocabulary, confident but respectful phrasing, and logical rather than emotional appeals.
