You want more quizzes? This week’s quiz is dressed to impress.

Welcome to Slate’s weekly news quiz. It’s Friday, which means it’s time to test your knowledge of the week’s news events. Your host, Ray Hamel, has concocted questions on news topics ranging from politics to business, from culture to sports to science.

At the end of the quiz, you’ll be able to compare your score with that of the average contestant, as well as with the score of a Slatester who has agreed to take the quiz on the record. This week’s contestant is staff writer Molly Olmstead.

Can you ace the quiz and beat Olmstead? Good luck!

A Japanese company earned a Guinness World Record when it harvested a giant radish that weighed in at just over 101 pounds. Don’t eat it all at once—excessive amounts may interfere with your thyroid and the gas produced just might propel you into the stratosphere. This week’s Slate News Quiz is pretty cool in a rad-ish sort of way.
