Logical Interpretation — Proverb Meaning “All that glitters is not gold.” What is the most accurate implication of this proverb in critical reasoning terms?

Introduction / Context:
This question tests proverb comprehension and logical interpretation. The classic proverb “All that glitters is not gold” warns against superficial judgments. In reasoning terms, we must identify the inference that captures the cautionary message about misleading appearances rather than a literal statement about metals or materials.

Given Data / Assumptions:

• The proverb highlights a contrast between appearance (glitter) and true value (gold).
• It is figurative, not a metallurgical claim.
• The task is to select the option that generalizes the warning about deceptive appearances.

Concept / Approach:
The proverb functions as an argument against hasty generalization from surface features. In critical thinking, it reminds us that a positive external property (shiny, attractive, glamorous) does not guarantee inner worth or authenticity. Therefore, the correct choice should express the broader caution: appearances can mislead.

Step-by-Step Solution:

Verification / Alternative check:
Rephrase the proverb: “Not everything that looks valuable is actually valuable.” This aligns exactly with the idea that glittering things may deceive observers about their real value.

Why Other Options Are Wrong:

• Non-metals also glitter: literal and irrelevant to the proverb’s moral.
• Only gold glitters: factually wrong and opposite in spirit.
• Not all metals glitter: again literal and unrelated to the message.

Common Pitfalls:
Reading proverbs literally or restricting them to physical substances instead of extracting the intended caution about judgment and value.

Final Answer:
Glittering things may be deceptive.
