We saw numbers this week from the Pew Research Center that made us wish we’d paid closer attention in science class.

The Pew Research Center recently surveyed 3,278 adults in the U.S to find out how much we know, or don’t know, about science. You can take the interactive quiz here.

We at Marketplace Weekend conducted our own unofficial survey by taking a few of the questions in the quiz and randomly asking strangers on the streets of Downtown L.A. One of the questions:
