Statement reads:
"Rattlesnakes molt exactly once a year."
How would you negate this? Is is better to use one statement that says "Rattlesnakes do not molt exactly once a year" or is it better to split it into two that each say "Rattlesnakes molt less than once a year" and "Rattlesnakes molt at least twice a year"? Or is the first statement logically equivalent to the combination of the second and third? Thanks
