The statement that most clearly demonstrates the author's bias by overstatement is option B: "Everyone in the United States supports the use of wind energy."
This assertion goes beyond a reasonable claim and presents an exaggerated, overly positive view of the level of support for wind energy. It is unlikely that every single person in the United States supports any particular idea or initiative, including the use of wind energy. The overstatement suggests a bias in the author's perspective, aiming to emphasize widespread approval and create a stronger endorsement for wind power than may actually exist.
The other statements (A, C, and D) convey information about the benefits and progress of wind power without making extreme claims. For instance, statement A highlights the positive impact of using wind power to reduce dependence on fossil fuels, which is a generally acknowledged benefit. Statement C discusses the steps the United States is taking in using wind power, providing a factual description of actions. Statement D proposes the construction of new wind power projects to address global warming, presenting a call to action without making an exaggerated claim.
In summary, while the overall message supports wind power, option B stands out as an instance of overstatement, potentially reflecting the author's bias by portraying a more universally favorable view than may be accurate.
