Final answer:
A source with emotionally-charged language is likely to be subjective or biased, as opposed to sources that use neutral and unemotional evidence, which are considered objective.
Step-by-step explanation:
A source that contains emotionally-charged language tends to be subjective or biased. Such language is used to evoke emotions in the reader and can influence the reader's perspective on a topic. A source that intends to be neutral and impartial will avoid using this type of language and instead present evidence in a factual and unemotional manner, which is known as an objective stance. It is crucial for researchers and students to distinguish between these different types of language to better assess the credibility and bias of a source.
