To identify the valid reasoning structure or invalid reasoning error for each symbolic argument, we need to analyze the logical form of each argument.**Argument #1:**- Premise:
- Premise:
- Conclusion:
This argument does not follow a standard logical form because the conclusion
is unrelated to the premises. Therefore, this represents an **invalid reasoning error** known as "irrelevant conclusion" or "non sequitur."**Argument #2:**- Premise:
- Premise:
- Conclusion:
This argument is invalid because it contradicts itself. If
and
are true, then
must be true, not
. This represents an **invalid reasoning error** known as "denying the antecedent."**Argument #3:**- Premise:
- Premise:
- Conclusion:
This argument is invalid because it assumes that if
is true, then
must also be true, which is not necessarily the case. This represents an **invalid reasoning error** known as "affirming the consequent."**Argument #4:**- Premise:
- Premise:
- Conclusion:
This argument is invalid because it incorrectly concludes
from
. The presence of
does not imply
. This represents an **invalid reasoning error** similar to "affirming the consequent."In summary:- Argument #1: Invalid reasoning error (irrelevant conclusion).- Argument #2: Invalid reasoning error (denying the antecedent).- Argument #3: Invalid reasoning error (affirming the consequent).- Argument #4: Invalid reasoning error (similar to affirming the consequent).
