Evaluating Truth and Validity Exercise

The arguments I will choose to evaluate for truth and validity will be taken from the Applications list 12.2 (a.-y.) at the end of Ch. 12 in The Art of Thinking.

Therefore, if the Social Security system is not further weakened, those same elderly may not have to fear poverty.” Again, the final step will be checking the argument for validity errors and determining if a legitimate assumption can be derived from the premise. The revised statement now has more validity and the assumption that those elderly that depend
