Live Science has a fun little quiz for those old enough to remember Tienanmen Square well.
* When did it all start?
* What started the protests?
* How many protesters ultimately gathered in the square?
* How many people were killed when the tanks rolled in June 4?
You want the answers? Go to Live Science. And on the final question, we know how many weren't killed: less than 241. That's the official Chinese Government estimate. If that's what the government is saying, we can rest pretty well assured that the actual number is a whole lot higher.
