Final answer:
Opinion papers express the author's personal ideas and beliefs and do not require citations or research.
Step-by-step explanation:
Unlike research-based papers, opinion papers rely solely on the author's ideas and beliefs. These papers are not supported by evidence or research, but rather express the author's personal opinions on a given topic. Unlike papers that require citations and references, opinion papers are subjective and do not rely on external sources for support. The author's opinions and beliefs are the main focus of these papers, making them different from research-based papers.
