Level 11-4

Prefixes #4 -- mixed prefixes

antifreeze, decode, abnormal, Hemisphere, midnight, outrun, semicircle, submarine, tricycle, underground

In this level, we use different prefixes for each of the ten words, making this a tough challenge!

For the word Hemisphere, it could be used in a way that either does or doesn't need capitalization; we used it as a proper noun in our sentence ("the Northern Hemisphere") and require it to be capitalized because we thought students would encounter it in that form more often.
