If “Some assassinations are morally justifiable actions” is false, what is the truth value of the following statements?

a. All assassinations are morally justifiable actions.
b. No assassinations are morally justifiable actions.
c. Some assassinations are not morally justifiable actions.

Use the traditional square of opposition to find the answers to these problems. When a statement is given as false, simply enter an “F” into the square of opposition and compute (if possible) the other truth values.
