6) Exercise 8.4, Group A, argument a

This one is in page 313.

You have to read both Group A and Group B, to do this one.

The directions, given in page 312, say:

Here follow a group of arguments (Group A, lettered a–o) and a group of argument forms (Group B, numbered 1–24).

Just do the following:

For the given argument (in Group A), indicate which of the argument forms (in Group B), if any, is the specific form of that argument.

This one (the given argument that you have to work with) is

A • B

Therefore, A

7) Exercise 8.7, argument 2

Just do B 2, given in page 322.

Use truth tables to determine the validity or invalidity of the following argument:

#2 is given as

Therefore, C V D

8) Exercise 8.8, statement A1
