Give any TWO reasons why many students commit to higher educationwithout having the required funds. go math book 5th grade lesson 10.6 Introduction and thesisOpposing and qualifying ideasStrong evidence in support of claimStyle and tone of languageA compelling conclusionCreating an Introduction and ThesisThe argumentative essay begins with an engaging introduction that presents the general topic. The thesis typically appears somewhere in the introduction and states the writers point of view.A Tip: Avoid forming a thesis based on a negative claim. For example, The hourly minimum wage is not high enough for the average worker to live on. This is probably a true statement, but arguments should make a positive case that affirms something. Instead of arguing something is not, an argument essay is stronger when it asserts something is Returning to the example above, a stronger thesis could focus on how the hourly wage is low or insufficient.Acknowledging Opposing Ideas and Limits to Your ArgumentBecause an argument implies differing points of view on the subject, you must be sure to acknowledge those opposing ideas. Avoiding ideas that conflict with your own gives the reader the impression that you may be uncertain, fearful, or unaware of opposing ideas. Thus it is essential that you not only address counterarguments but also do so respectfully.Try to address opposing arguments earlier rather than later in your essay. Rhetorically speaking, ordering your positive arguments last allows you to better address ideas that conflict with your own, so you can spend the rest of the essay countering those arguments. This way, you leave your reader thinking about your argument rather than someone elses. You have the last word.Acknowledging points of view different from your own also has the effect of fostering more credibility between you and the audience. They know from the outset that you are aware of opposing ideas and that you are not afraid to give them space.It is also helpful to establish the limits of your argument and what you are trying to accomplish. In effect, you are conceding early on that your argument is not the ultimate authority on a given topic. Such humility can go a long way toward earning credibility and trust with an audience. Audience members will know from the beginning that you are a reasonable writer, and audience members will trust your argument as a result. For example, in the following concessionary statement, the writer advocates for stricter gun control laws, but she admits it will not solve all of our problems with crime: y-2=-5(x-2) slope intercept form What is the length of the hypotenuse?
