Final answer:
Something that is plausible is believable, as it is a claim or scenario that is reasonable to accept based on evidence or likelihood. Plausibility is aligned with being achievable, relevant, and time-bound and requires consistency with reality and known truths.
Step-by-step explanation:
Something that is plausible is believable. This relates to the way we assess statements or scenarios based on evidence or likelihood. Plausibility indicates that a given statement could easily be true or is reasonable to accept, without necessarily having to be the absolute truth. In the context of the options provided, plausible corresponds to something being believable, which aligns with the mentioned criteria of being achievable, relevant, and time-bound as it frames a situation or claim within the bounds of reason and evidence. Therefore, the correct response to the question is (a) believable.
For example, if a businessman believes they deserve a raise due to their hard work and the value they add to the company, this belief can be seen as plausible. However, it represents a response of rationalizing the situation by focusing on the inherent value of his hard work.
It's essential for beliefs to correspond to reality and be consistent with known truths - this underpins the concept of plausibility. Something far less likely would not meet the standard of being plausible, nor would propositions that are merely hopeful or merely manageable without additional substantiation.
