✅ Answer: Mount Everest. It was STILL the tallest — it just hadn’t been discovered yet.
A mountain doesn’t become tall when humans find it. It was already there. Everest was the tallest mountain in the world for millions of years before anyone measured it.
Your brain heard “before it was discovered” and assumed the answer must be a DIFFERENT mountain. But discovery doesn’t change reality — it only changes human awareness.
This is called the observation bias — the false belief that things only exist or become true when we observe them.
