Short Answer 
To effectively use a quotation to support your argument, first select a relevant quote, introduce it by establishing the speaker’s credibility, and then connect it back to your main point to reinforce your argument. This process ensures that the quotation is seamlessly integrated into your discussion and enhances the strength of your claim.
Step 1: Select a Relevant Quotation
To effectively reinforce your argument, first choose a strong direct quotation that relates to your main point. In this case, using President Obama’s words enhances the discussion about the sentimental value of the penny. Consider what he is expressing about the penny and how it ties to your argument.
Step 2: Introduce the Quotation
Once you have selected the quotation, introduce it in a way that sets the context for your readers. This can involve mentioning who the speaker is and why their opinion is credible. For example, stating “In 2013, President Obama acknowledged…” establishes authority and ensures that the audience understands the relevance of the quote.
Step 3: Connect the Quotation to Your Argument
Finally, after presenting the quote, explicitly connect it back to your argument to reinforce the point you are making. This helps integrate the quote seamlessly into your discussion. You might say that the quotation highlights the widespread emotional connection people have with the penny, thus supporting your broader claim effectively.
