Explanation:
The main purpose of argumentative writing is **to support an opinion with effective reasons and evidence**.
Here's why the other options are not the main purpose of argumentative writing:
* **To report the results of research or an experiment:** This is the main purpose of **informative writing**, which aims to present factual information without taking a specific stance or trying to persuade the reader.
* **To share firsthand knowledge of a topic:** This can be a **supporting element** in argumentative writing, but it's not the main purpose. You can share your personal experiences to back up your arguments, but the focus should still be on convincing the reader of your opinion.
* **To juxtapose contrasting ideas for effect:** This can be a **literary device** used in argumentative writing to highlight the strengths of your own position by comparing it to other viewpoints. However, the main goal is still to persuade the reader to agree with your argument.
Therefore, while other forms of writing may involve some aspects of argumentation, their primary purpose is different from the core objective of argumentative writing, which is to convince the reader of a particular point of view through strong reasoning and evidence.
I hope this clarifies the main purpose of argumentative writing! Let me know if you have any other questions.
