Section1
Direction: Two statements are given in the question, followed by two conclusions numbered 1 and 2. You have to take the given two statements to be true even, if they seem to be at variance from commonly known facts. Read the conclusions and then decide which of the given conclusions logically.
1.  Statements:
Some note books are books.
All books are papers.
Conclusions:
1. Some notebooks are papers.
2. No paper is notebook.  (a)If only Conclusion 1 follows  (b)If only Conclusion 2 follows  (c)If either Conclusion 1 or 2 follow  (d)If neither 1 nor 2 follows 

Answer is: C
This is a special case as a combination of universal negative and particular affirmative.
Hence, either some notebooks are papers or no paper is notebook.
2.  Statements:
All huts are mansions.
All mansions are temples.
Conclusions:
1. Some temples are huts.
2. Some temples are mansions.  (a)If only Conclusion 1 follows  (b)If only Conclusion 2 follows  (c)If either Conclusion 1 or 2 follow  (d)If both Conclusions 1 and 2 follow 

Answer is: DThis shows the case of universal affirmative proposition. so,
Clearly, some temples are huts as well as some temples are mansions. So, both conclusions follow.
3.  Statements:
All pens are pencils.
No pencil is cap.
Conclusions:
1. All caps are pencils.
2. Some caps are pencils.  (a)If only Conclusion 1 follows  (b)If only Conclusion 2 follows  (c)If either Conclusion 1 or 2 follow  (d)If neither 1 nor 2 follows 

Answer is: D
Clearly, neither Conclusion 1 nor 2 follow.
4.  Statements:
All fish are tortoise.
No tortoise is a crocodile.
Conclusions:
1. No crocodile is a fish.
2. No fish is a crocodile.  (a)If only Conclusion 1 follows  (b)If only Conclusion 2 follows  (c)If either Conclusion 1 or 2 follow  (d)If neither Conclusion 1 nor 2 follows 

Answer is: D
Clearly, no crocodile is fish and no fish is a crocodile.
5.  Statements:
All trucks fly.
Some scooters fly.
Conclusions:
1. All trucks are scooters.
2. Some scooters do not fly.  (a)If only Conclusion 1 follows  (b)If only Conclusion 2 follows  (c)If either Conclusion 1 or 2 follow  (d)If neither Conclusion 1 nor 2 follows 

Answer is: B
Clearly, some scooters do not fly.
6.  Statements:
All leaders are good team workers.
All good team workers are good orators.
Conclusions:
1. Some good team workers are leaders.
2. All good orators are leaders.  (a)If only Conclusion 1 follows  (b)If only Conclusion 2 follows  (c)If either Conclusion 1 or 2 follow  (d)If both Conclusions 1 and 2 follow 

Answer is: A
Clearly, some good team workers are leaders.
7.  Statements:
Some papers are pens.
Angle is a paper.
Conclusions:
1. Angle is not a pen.
2. Angle is a pen.  (a)If only Conclusion 1 follows  (b)If only Conclusion 2 follows  (c)If either Conclusion 1 or 2 follow  (d)If both Conclusions 1 and 2 follow 

Answer is: C
This is a special case. So, either Conclusion 1 or 2 follows.
8.  Statements:
Lata is a beautiful and intelligent girl.
She is very good.
Conclusions:
1. All beautiful girls are intelligent.
2. Beauty and intelligence are the essential factors of goodness.  (a)If only Conclusion 1 follows  (b)If only Conclusion 2 follows  (c)If either Conclusion 1 or 2 follow  (d)If neither Conclusion 1 nor 2 follows 

Answer is: D
Form above, it is clear that none of the conclusion follows.
9.  Statements

All readers are lawyers.
Conclusions:
1. Some lawyers are readers.
2. Some readers are writers.  (a)If only Conclusion 1 follows  (b)If only Conclusion 2 follows  (c)If either Conclusion 1 or 2 follow  (d)If neither Conclusion 1 nor 2 follow 

Answer is: A
Clearly, some lawyers are readers.
10.  Statements:
All players are doctors.

1. Some doctors are players as well as actors.
2. All actors are doctors.  (a)If only Conclusion 1 follows  (b)If only Conclusion 2 follows  (c)If either Conclusion 1 or 2 follow  (d)If neither Conclusion 1 nor 2 follows 

Answer is: D
From above, it is clear that none of the conclusion follows. Comments
