The refrigerator and freezer maker Sub-Zero is partnering with our charity partner FoodCorps to bring you the "Freshness IQ Challenge," a digital quiz that educates you on the importance of proper food storage tips.

Initial scores show that more than 50 percent of respondents don't know the basics (the best place to store milk, what fruits and veggies shouldn't be stored next to each other, etc.). Take the quiz yourself and see how storage savvy you are.

As a bonus, for every quiz taken, Sub-Zero is donating $1 up to $25,000 to FoodCorps' wonderful cause! The recently hit the 10,000 milestone mark!

You can check out the quiz here.
