Statements-
1. All phones are wires.
2. All switches are wires.
3. Some wires are poles.
4. Some poles are not phones.
Conclusion-
1. All switches are poles is a possibility.
2. Some poles are not wire.
3. Some poles being phone is a possibility.
All switches are wires (A) + Some wires are poles(I) ⇒ Probable conclusion ⇒ Some switches are poles (I) ⇒ Probable conclusion ⇒ All switches are poles is a possibility. Hence conclusion I follows. Some wires are poles(I) ⇒ Comversion ⇒ Some poles are wire(I). Hence conclusion II does not follow. Some poles are not phones(O) ⇒ Probable conclusion ⇒ Some poles being phone is a possibility(I). Hence conclusion III follows. Alternate Method:
