Question

Choose the correct option about conclusion drawn from the statements given below

Statements:

All the windows are doors.

No door is a wall.
Conclusions:
1. Some windows are walls.
2. No wall is a door.

• A. Only (1) conclusion follows
• B. Only (2) conclusion follows
• C. Either (1) or (2) follows
• D. Neither (1) nor (2) follows
• E. Both (1) and (2) follow

Answer 1

Answer: (B)

Only (2) conclusion follows

From the above Venn diagram we made some assumptions on conclusion

Some windows are walls : False

No wall is a door : True

Therefore only second conclusion is right

Hence the correct answer is option $B$.
