The proper style for an argumentative essay is __________.

The proper style for an argumentative essay is formal and objective. This means that the writer should maintain a serious and respectful tone throughout the essay. It is important to provide clear and logical arguments supported by evidence and data rather than personal opinions or emotional appeals. The use of credible sources, facts, statistics, and logical reasoning is essential to persuade the audience effectively. Additionally, a well-structured argumentative essay should include an introduction that presents the main argument, body paragraphs that discuss the supporting evidence, and a conclusion that summarizes the key points and reiterates the thesis. Clarity and coherence in writing are also critical to convey the argument successfully.
