What does it mean if something is described as "potent"?

Describing something as "potent" indicates that it has the capacity to produce a strong or powerful effect. In various contexts such as medicine, chemistry, or even in daily conversation, a potent substance or treatment is one that can demonstrate significant efficacy or impact. For instance, a potent medication is one that can effectively address a specific condition, showcasing a higher degree of effectiveness in achieving desired results.

When considering the other choices, they reflect characteristics that are contrary to or less than the strong implications of the word "potent." For example, describing something as ineffective directly opposes the idea of potency; it suggests that the item has little or no effect at all. Supportive implies a more passive role, contributing positively but without necessarily exerting strong influence or effects. Lastly, causing minor effects indicates a weak or insubstantial impact, which stands in sharp contrast to the idea of being potent. In summary, "potent" specifically denotes an ability to produce significant and powerful effects, making the correct answer clear.
