Answers with Explanations:
1. 1. 2;
• Some wins are trophies (I) + Some trophies are cups (I) = I + I = No conclusion. Hence conclusion I does not follow.
• Again, Some trophies are cups (I) + No cup is a prize (E) = I + E = O = Some trophies are not prizes. But the possibility in II exists. Hence conclusion II follows.
2. 2. 1;
• All coats are deposits (A) + All deposits are sheets (A) = A + A = A = All coats are sheets. Hence conclusion I follows. No layer is a coat (E) + All coats are deposits (A) = E + A = O* = Some deposits are not layers (O*). Hence conclusion II follows.
3. 3. 4;
• No apartment is a hall (E) + Some halls are rooms (I) = E + I = O* = Some rooms are not apartments. Hence conclusion II does not follow. Now, Some flats are apartments (I) + No apartment is a hall (E) = I + E = O = Some flats are not halls (O) + Some halls are rooms (I) = O + I = No conclusion. Hence conclusion I does not follow.
4. 4. 3;
• Some trophies are cups (I) + No cup is a prize (E) = I + E = O = Some trophies are not prizes. Hence conclusion I does not follow.
• Again, Some wins are trophies (I) + Some trophies are not prizes (O) = I + O = No conclusion. Hence conclusion II does not follow.
5. 5. 1;
• Some codes are secrets (I) → conversion → Some secrets are codes (I). Thus, the possibility in I exists. Hence conclusion I follows.
• Again, Some codes are secrets (I) + All secrets are puzzles (A) = I + A = I = Some codes are puzzles (I) ) → conversion → Some puzzles are codes. Hence conclusion II follows.
