Final answer:
The first paragraph example integrates quotations using the MLA style, while the second paragraph example uses the APA style.
Step-by-step explanation:
In the first paragraph example, quotations are integrated using the MLA style. The author's last name and the page number are included in parentheses at the end of the quotation. For example: 'This is a quote' (Smith 10). In the second paragraph example, quotations are integrated using the APA style. The author's last name and the year of publication are included in parentheses after the quotation. For example: 'This is a quote' (Smith, 2020).
