13. Question
Which of the conclusions logically follows from the given statements?
Statements:
All rats are bells.
All bells are cars.Conclusions:
I. All bells are rats.
II. Some cars are neither bells nor rats.
III. No car is a rat.Hint
1st Statement + 2nd Statement gives the conclusion

Which of the conclusions logically follows from the given statements?
Statements:
All roads are trees.
No tree is soap.Conclusions:
I. No soap is road.
II. Some trees are roads.

Hence, conclusion III follows.
Conclusion I follows from the conversion of conclusion III. Hence, All follow. - Question 15 of 20
15. Question
Which of the conclusions logically follows from the given statements?
Statements:
Some hotels are bricks.
All bananas are bricks.Conclusions:
I. Some bananas are hotels.
II. Some bricks are hotels.
III. No banana is hotel.Hint
Conclusion II follows from the conversion of first Statement.
Now, 2nd statement + conversion of 1st Statement gives no conclusion (A+I⇒no conclusion).
Hence, conclusions I and III do not follow.
But conclusion I and conclusion III make an IE-type complementary pair.
Hence either conclusion I or conclusion III follows. - Question 16 of 20
16. Question
Which of the conclusions logically follows from the given statements?
Statements:
Some books are lamps.
Some lamps are rods.Conclusions:
I. Some books are rods.
II. No rod is either book or lamp.
III. All rods are lamps.Hint
1st Statement + 2nd statement gives no conclusion (I+I⇒no conclusion).
Therefore, conclusion I does not follow.
Again conversion of 2nd statement gives the conclusion “Some rods are lamps”.
Hence, conclusions II and III do not follow. - Question 17 of 20
17. Question
Which of the conclusions logically follows from the given statements?
Statements:
All tables are boxes.
Some boxes are windows.Conclusions:
I. Some tables are windows.
II. All boxes are tables.
III. No window is a table.Hint
1st Statement + 2nd statement gives no conclusion. [A+I⇒no conclusion].
Hence, conclusion I and conclusion III do not follow independently.
But, conclusion I and conclusion III make a complementary pair (IE-type).
Hence, either I or III follows.
Conclusion II does not follow because “All tables are boxes” gives only the following conclusions:
1. Some tables are boxes.
2. Some boxes are tables. - Question 18 of 20
18. Question
Which of the conclusions logically follows from the given statements?
Statements:
No room is tiger.
All tigers are goatsConclusions:
I. Some goats are rooms.
II. All goats are rooms.
III. Some goats are tigers.Hint
1st statement + 2nd statement gives the conclusion
“Some goats are not rooms” [E+A⇒O*].
Thus, conclusions I and II do not follow.
Conclusion III follows from second statement. - Question 19 of 20
19. Question
Which of the conclusions logically follows from the given statements?
Statements:
Some cars are roads.
Some roads are buses.Conclusions:
I. Some roads are cars.
II. Some buses are cars.
III. Some buses are roads.Hint
1st statement + 2nd statement gives no conclusion
[I+I⇒no conclusion].
Hence, conclusion II does not follow.
Conclusion I follows from conversion of 1st Statement.
On a similar basis, conclusion III also follows. - Question 20 of 20
20. Question
Which of the conclusions logically follows from the given statements?
Statements:
Some men are lions.
All foxes are lions.Conclusions:
I. Some foxes are men.
II. Some lions are men.
III. All lions are foxes.Hint
Conversion of 1st Statement gives the conclusion
“Some lions are men”.
Hence, conclusion II follows [say statement].
Now, 2nd statement + conclusion II gives no conclusion
[A+I⇒no conclusion].
Therefore, conclusion I does not follow.
Conclusion III does not follow because an A-type statement gives I-type conclusions.
