Final answer:
A fact can be verified as it is based on evidence and data, while an opinion is a personal belief that lacks such verification. The correct answer is option d.
Step-by-step explanation:
The primary difference between a fact and an opinion is that a fact can be verified. A fact is information that is true and can be proven correct or accurate, built upon evidence and data. It is established by experiment or observation, making it reliable under specific conditions of observation. In contrast, an opinion expresses a personal judgment, conclusion, or attitude that may or may not be accurate and cannot be verified in the same way.
In research, the distinction becomes apparent, as researchers rely on empirical evidence to establish facts, whereas opinions are not subject to this rigorous process. Factual statements stand in contrast to opinions, which, even though they may be informed, are still subject to personal belief and cannot be confirmed through objective means. It is important in academic and analytical writing to base assertions on facts when the objective is to provide information or analysis.
Examples of factual statements are those backed by compelling evidence, and they do not change regardless of personal belief or opinion. On the other hand, opinions form the basis of claims that require support from evidence in argumentative writing, but they are not the foundational elements of informative or analytical writing.
Therefore, the correct option to describe the primary difference between a fact and opinion is D. can be verified.
