OBSCURE Choose the word opposite in meaning to the one given above.

Answer: Apparent

Why: "Obscure" describes something that is hidden, not well known, or difficult to understand. The correct antonym should convey clarity or obviousness.

• Meaning of "obscure": hidden, unknown, or not clearly expressed.

• Meaning of "apparent": clear, obvious, or easily perceived.

Why the other choices are incorrect:

• "Ponderous" means heavy, slow, or dull — not related to clarity.

• "Thoughtful" means considerate or reflective — not an opposite of hidden or unclear.

• "Heedless" means careless or inattentive — it does not mean clear or obvious.

Conclusion: "Apparent" is the best antonym for "obscure" because it conveys clarity and obviousness.
