Statement & Argument — Do synonyms mean exactly the same? Arguments: I. Yes, a rich language has many words for the same expression. II. No, each so-called synonym carries a distinct nuance and may slightly change meaning in context.

Introduction / Context:
This language-reasoning item asks whether synonyms are semantically identical. In lexicography and pragmatics, “synonymy” is typically near-equivalence, not perfect identity; register, tone, collocation, and connotation often differ. Strong arguments should reflect this linguistic reality.

Given Data / Assumptions:

• Words considered synonyms often diverge in tone (formal vs informal), domain (technical vs general), or collocations.
• Meaning in use depends on context; small differences can alter implications.

Concept / Approach:
We test whether each argument properly addresses the claim of exactness. An argument that acknowledges nuance is stronger than one that simply asserts multiplicity of words.

Step-by-Step Solution:
Argument I: Merely claims rich languages have many words for the “same expression.” It does not prove exact identity; quantity ≠ sameness. Weak.Argument II: States that each synonym differs and can change meaning slightly when substituted. This aligns with known linguistic behavior (differences in connotation, register, collocation). Strong.

Verification / Alternative check:
Consider “slim” vs “skinny,” “residence” vs “home”: near-synonyms with distinct tone and usage.

Why Other Options Are Wrong:
“Either” would elevate I to strong status incorrectly. “Neither” ignores the validity of II.

Common Pitfalls:
Equating dictionary gloss overlap with perfect interchangeability.

Final Answer:
Only Argument II is strong.
