Final answer:
Correct the subject-verb agreement error in the sentence by matching the singular subject with the appropriate verb form.
Explanation:
The correct sentence to fix the subject-verb agreement error is:
- A student who submits a research paper with a weak thesis and multiple sources is going to receive a higher grade than students who submit a research paper with a strong thesis and only a few sources.
In this sentence, the verb 'submits' matches the singular subject 'a student,' while 'submit' would be incorrect because it is plural and does not agree with the singular subject 'a student.'
