“Common Knowledge Trap” looks friendly at first glance and then quietly checks your assumptions. You’ll face 10 cleanly written questions that target half-remembered facts, popular myths, and details people mix up. You have 100 seconds to get at least 5 right.

Each item gives four choices—one correct, three plausible. The interface stays out of your way so you can focus on the wording. Answers grade instantly, and your score updates as you go. After the round, scan your misses and try again; repetition here builds sharp instincts fast.

A few habits help: beware absolutes like “always” and “only,” check units and time frames, and prefer precise facts over common sayings. If two answers seem reasonable, eliminate the broader one and choose the one with the tighter definition. Think you won’t fall for the easy stuff? Press Start and prove it.
