To identify the valid reasoning structure or invalid reasoning error for each argument, let's analyze them one by one:**Argument #1:**- Premise:
- Premise:
- Conclusion:
This argument follows the logical form known as **Modus Ponens**, which is a valid form of reasoning. If
implies
and
is true, then
must also be true.**Argument #2:**- Premise:
- Premise:
- Conclusion:
This argument represents an invalid reasoning error known as **Denying the Antecedent**. Just because
is false does not necessarily mean that
is false.**Argument #3:**- Premise:
- Premise:
- Conclusion:
This argument represents an invalid reasoning error known as **Affirming the Consequent**. Just because
is true does not necessarily mean that
is true.**Argument #4:**- Premise:
- Premise:
- Conclusion:
This argument follows the logical form known as **Modus Tollens**, which is a valid form of reasoning. If
implies
and
is false, then
must also be false.In summary:- Argument #1: Modus Ponens (valid)- Argument #2: Denying the Antecedent (invalid)- Argument #3: Affirming the Consequent (invalid)- Argument #4: Modus Tollens (valid)
