ANSWERS WITH EXPLANATION:
1. 2; Some balls are locks. + All locks are keys (I + A  I) = Some balls are keys + Some doors
are keys (I + I  no conclusion). So, I does not follow. As there is no negative statement, so
possibility case is true.
2. 5; Some balls are locks + All locks are keys (I + A  I). So, II follows. Some doors are keys
can be derived from ‘All doors are keys’. So, possibility case follows.
3. 1; Some ants are birds conversion Some birds are ants + All ants are cobras
(I + A I) Some birds are cobras.
All lizards are birds. + Some birds are cobras (A + I no conclusion). But in case of
possibility All cobras being lizards can be true.
4. 5
5. 4; ‘No’, statement can never lead to ‘All’. So, I does not follow.
And Some shares are debentures + No debenture is an equity (I + E O) = Some shares are
not equities. So, possibility of II is also ruled out.

6. 5; Some shares are not equities. This does not rule out the possibility of I. No debenture is
an equities + Some equity are capital (E + I O) Some capitals are not debentures. This
does not rule out the possibility of II.
7. 2; All apartments are buildings + All buildings are cottages = A + A  A = All apartments
are cottages. Hence, I does not follow.
Some apartments are huts (I)  conversion  Some huts are apartments (I) + All apartments
are buildings (I + A  I) = Some huts are buildings. Hence the possibility of II exists.
8. 5; All staplers are printers + No printer is a computer = A + E stapler is a computer
+ All computers are machines. = E + A O = Some machines are not staplers. This does
not rule out the possibility of I. All staplers are printers + No printer is a computer = A + E
 E = No stapler is a computer. Hence, II also follows.
9. 5; I is true because All planets are fans. For II: All planets are fans  Conversion  Some
fans are planets + No planet is a universe.  Some fans are not universe. This does not rule
out the possibility of II.
10. 1; Some professors are intelligent (I) + No intelligent is honest = I +E  O = Some professors
are not honest. This leaves us with the possibility of I. While II does not follow because ‘No
Intelligent is an honest.’
11. 4; All tins are copper + No copper is a metal = A + E  E = No tin is a metal. So the
possibility of I is ruled out. No pin is a tin + All tins are copper = (E + A  O = Some
coppers are not pins. So, II does not follow.
