Lethargic is related to Vital in a pair of opposites. In the same way, Trite is related to which of the following words?

Introduction / Context:
This analogy checks knowledge of antonyms. Lethargic and Vital form a pair where one word expresses low energy and the other expresses strong energy. You must find the word that stands in a similar opposite relationship to Trite.

Given Data / Assumptions:
1) Lethargic describes someone who is very tired, sluggish, or lacking energy.

Concept / Approach:
The first pair contrasts low energy with high energy. Trite refers to something overused, stale, or lacking originality. The opposite of Trite would be something fresh, original, or distinctive. Among the options, Unique best matches that opposite meaning, since it means one of a kind or highly original. The other options either relate to laziness or physical appearance and do not address originality.

Step-by-Step Solution:
Step 1: Note that Lethargic describes low energy while Vital describes high or essential energy. Step 2: Recognise that the relationship is one of antonyms rather than synonyms. Step 3: Define Trite as overused, cliched, or lacking in freshness and originality. Step 4: Search the options for a word that expresses a strong sense of originality. Unique means one of a kind or unlike anything else, capturing fresh and original quality. Step 5: Confirm that this forms a clear opposite pair similar in spirit to Lethargic and Vital.

Verification / Alternative check:
Test the other options. Slug is a noun for a slow creature and used informally for a lazy person, which would be closer to Lethargic, not the opposite of Trite. Lazy also relates to lack of energy, and Skinny is about physical thinness. None of these address originality or lack of it. Only Unique directly opposes the idea of being stale and overused.

Why Other Options Are Wrong:
Slug and Lazy both concern energy level rather than creativity or freshness. Skinny describes body shape and is unrelated to the concept of originality. These words do not form an antonym pair with Trite. Therefore selecting any of them would break the analogy pattern established by Lethargic and Vital.

Common Pitfalls:
A typical mistake is to misinterpret Trite as lazy or dull in an energetic sense, which might mislead someone into picking Lazy. However, Trite is about the originality of ideas or expressions, not physical or mental energy. Carefully checking dictionary meaning or recalling usage examples helps avoid this confusion.

Final Answer:
Thus, the correct word that stands opposite to Trite in the same way as Vital stands opposite to Lethargic is Unique. The final pair is Trite : Unique.
