Hello fodog 414,

This may have belonged in the high school level section but  i'm new here so i'm not sure, but it didn't require any paper or anything.

Remember that intervals with squarish brackets [ , ] include the numbers listed, and the curved brackets ( , ) do NOT.

So   1. A
       2. B
       3. E
       4. D
       5. C
