Provide a direct proof for the argument. For every real numbers b and c, c≠0, |b/c|=|b|/|c|.
Instructions: For each argument below, evaluate the truth of each premise (write “true,”“false,” or “questionable”). Then evaluate the argument’s support (write “valid” or“invalid,” and briefly explain why). Finally, determine the overall quality of theargument (write “sound” or “unsound”), and briefly explain whySAMPLE: P1) Some dads have a beard.P2) All bearded people are mean.C) Some dads are mean.Truth of premise 1: trueTruth of premise 2: questionable (“mean” is subjective)(true, false, or questionable)Support: valid(valid or invalid)Why: the premises establish that bearded dads are mean,so some dads (the ones with beards) are meanOverall: unsound(sound or unsound)Why: fails the truth test -- premise 2 is not true1.
