What does the term "adulterate" primarily refer to?

The term "adulterate" primarily refers to the act of corrupting, debasing, or making something impure. This is often used in contexts where a substance, such as food or drink, is mixed with inferior or harmful components, thereby diminishing its quality or purity. The process of adulteration can have negative implications, as it compromises the integrity of the original product.

In contrast, enhancing the quality of something, purifying a substance, or strengthening an argument focuses on improvement or integrity rather than degradation. Therefore, these other choices do not align with the true meaning of "adulterate." The concept centers around the introduction of unwanted elements, which directly ties into the definition of making something impure.
