Syllogism - Intermediate Level: possibility cases INTERMEDIATE

Definite Conclusion Analysis:

Venn Diagram:
Step 1: All mammals are wild → mammals inside wild
Step 2: No wild is a herbivores → wild and herbivores completely separate
Step 3: Since mammals inside wild, mammals also doesn't touch herbivores

Analytical Method:
All mammals are wild (A) + No wild is a herbivores (E) = A + E = E
Result: No mammals is a herbivores

Checking Conclusions:

✓ Conclusion I: "No mammals is a herbivores" - DEFINITE CONCLUSION - FOLLOWS

✗ Conclusion II: "All herbivores being mammals is a possibility"
Since definite negative exists ("No mammals is a herbivores"), this possibility is IMPOSSIBLE
DOES NOT FOLLOW

Important Rule: When definite negative conclusion exists between terms, positive possibility becomes FALSE.

Answer: Only conclusion I follows

Temporal Syllogism Analysis:
Temporal syllogisms involve time-based conditions integrated with logical statements.

Logical Chain:
All athletes who win medals are athletes who train regularly + All athletes who train regularly train for more than 6 hours daily = All athletes who win medals train for more than 6 hours daily
Some athletes who win medals are athletes who become famous + All athletes who win medals train for more than 6 hours daily = Some athletes who become famous train for more than 6 hours daily

Checking Conclusions:
✓ Conclusion I: "Some athletes who become famous train for more than 6 hours daily" - FOLLOWS
✓ Conclusion II: "Some people who train for more than 6 hours daily are athletes who become famous" - Conversion of I - FOLLOWS
✗ Conclusion III: "All athletes who become famous are definitely athletes who win medals" - Only "some" given, not "all" - DOES NOT FOLLOW

Answer: Only conclusions I and II follow

Multi-Dimensional Syllogism Analysis:
