- Step 1: Define the word. "Ephemeral" means lasting for a short time, often fleeting or transient.
- Step 2: Compare with options. Option (1) "Permanent" is the opposite, meaning lasting forever. Option (2) "Temporary" aligns with short-lived. Option (3) "Ancient" refers to old age, unrelated. Option (4) "Complex" refers to intricacy, not duration.
- Step 3: Verify synonym. "Temporary" is a direct synonym for ephemeral, as both imply brevity.
- Step 4: Eliminate distractors. Permanent, ancient, and complex do not relate to the concept of short duration.
- Step 5: Conclusion. Option (2) is correct.
