HELLO, SEXY NOGGIN! It's time once again to put that brainy-brain to the test with this week's edition of POP QUIZ PDX—our weekly, local, sassy-ass trivia quiz. And this week, we'll be testing your knowledge about "shadow" mayors and Republicans, less successful local news quizzes, and what radioactive creature you'd MOST like to be bitten by! Also, guess what? You can enter to win FREE PIZZA from our friends at the always delicious Atlas Pizza, just for taking the quiz and signing up for our brainy newsletters! (Pizza: the ultimate brain food!)

But before we continue... HOW DID YOU DO ON THE PREVIOUS QUIZ? Dang, you people are getting smarter by the day! And as for who you thought should replace Biden as the upcoming presidential nominee... well... Elizabeth Warren, I hope you're a Pop Quiz fan!

OKAY, TIME FOR A NEW QUIZ! Take this week's quiz below, take our previous pop quizzes here, and come back next week for a brand spankin' new quiz! (Having a tough time answering this quiz? It's probably because you aren't getting Mercury newsletters! HINT! HINT!) Now crank up that cerebellum, because it's time to get BRAINY!
