Step-by-step explanation:
The important difference between the 'Excerpt from Federal-Aid Highway Act of 1956' and the main part of the text is that the excerpt provides the specific language of the government document, rather than just general descriptions found in the main text. The text examples from a lesson on integrating quotations illustrate the distinctions between great and good writers.
The lesson on editing for clarity and precision also shows the process of refining writing from a more complex to a more succinct form, which directly relates to how a government document can begin with complex language but end with a more refined and precise version. Finally, the second paragraph example represents a technique of integrating quotations from a source in a fluid and grammatically correct manner, similar to how a government document's final language is precise and integrates information smoothly.
