The problem with using the sentence "I agree with Mr. Jones's contention that the government is not meeting the healthcare needs of the middle-class American" in a research paper is, it uses first person point of view.
Answer: Option B.
Step-by-step explanation:
Research paper is a type of academic writing where a person analyses, and interprets the information bases on the original work. Such type of writing often discourage the use of first person point of view.
In the sentence, I’ agree with Mr. Jones's contention that the government is not meeting the healthcare needs of the middle-class American’, ‘I’ represents the first person pronoun. Such sentences cannot be used in research paper because it may result in personal bias and might also sound opinionated.
