Final answer:
In analogy, 'foggy' is to 'clear' as 'vague' is to 'explicit' where 'explicit' represents clarity and specificity, the opposites of being vague and foggy.
Step-by-step explanation:
The analogy presented in the question links the concept of something being foggy with its opposite, being clear. Similarly, if we consider the word vague, which implies a lack of clarity or precision, we would seek an antonym that conveys specificity and distinctness. The direct opposite of vague, in this case, would be explicit or precise.
