Final answer:
Lana should revise her paper, proofread for errors, and then turn it in to her instructor.
Step-by-step explanation:
Once Lana has finished writing her research paper, the next step she should take is to revise the substance of what she has written. This means re-reading her paper and making any necessary changes to improve the overall content, structure, and clarity of her arguments.
After revising, Lana should then proofread her paper to check for small errors such as spelling, grammar, and punctuation mistakes. This step is important to ensure the paper is polished and error-free.
Finally, once Lana is satisfied with her revisions and proofreading, she can turn in her research paper to her instructor. It is important to submit the paper as soon as possible to meet any deadlines.
