There could be a few explanations for this. First, the answer you found online may be wrong. Anyone can post information on the Internet, but it doesn’t mean it’s right. We’ve put together a great guide to help you Evaluate Online Information. A second reason there may be a difference is that some information changes over time. Capital cities change their name. Historians discover new facts that change what we thought we knew. It’s a good idea to check when web pages were last updated, so you can tell if the information is up-to-date. And the third reason is, we might be wrong. Like we just said, information changes. If you think we might have a mistake in our quiz, please let us know!
