  • Although this workout is based on  the 17th edition of the Manual, the styles covered in this quiz either are the same as in the 16th edition or were not previously addressed.
  • These questions are designed to test knowledge of The Chicago Manual of Style, which prefers Merriam-Webster’s Collegiate Dictionary, 11th edition. Other style guides may follow a different dictionary.
