Welcome back to Slate’s weekly news quiz. I’m your host, 74-time Jeopardy! winner Ken Jennings.

Every Friday I’ll be testing your knowledge with 12 challenging questions on the week’s news events, big and small, including happenings in science, sports, politics, and culture both high and low. The questions are multiple-choice, and time is of the essence: You have 30 seconds to answer, and as the seconds tick away, the question’s point value drops from 50 all the way down to zero, so you’ll want to click on your answer as fast as you possibly can. There’s no penalty for an incorrect answer, so feel free to take a guess if your puny human brain fails you.

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 whom I’ve talked into taking the quiz on the record. This week’s contestant is Slate associate editor J. Bryan Lowder.

Think you can ace my quiz and beat Lowder? Good luck!
