- Question
Statements: All doors are roads. No road is fruit. Some flowers are doors.
Conclusions:
- Some fruits are doors.
- Some fruits are flowers.
- Some roads are flowers.
- No fruit is flower.
Options- A. Only either II or III, and IV follow
- B. Only either II or IV, and III follow
- C. Only either II or IV, and I follow
- D. Only either II or IV follows
- E. All follow
- Correct Answer
- Only either II or IV, and III follow
ExplanationAll doors are roads. No road is fruit.Since both the premises are universal and one premise is negative, the conclusion must be universal negative and should not contain the middle term. So, it follows that 'No door is fruit.'
Some flowers are doors. All doors are roads.
Since one premise is particular, the conclusion must be particular and should not contain the middle term. So, it follows that 'Some flowers are roads'. Ill is the converse of this conclusion and so it holds.
Some flowers are roads. No road is fruit.
Since one premise is particular and the other negative, the conclusion must be particular negative and should not contain the middle term. So, it follows that 'Some flowers are not fruits'. II and IV involve the extreme terms and form a complementary pair. Thus, either II or IV follows.

- E. All are strong Discuss
Correct Answer: Only II is strong

- B. Only conclusion II follows
- C. Either I or II follows

Since the accident has caused concern, it must be fatal. So, I follows. The use of the word 'again' in the statement justifies the fact mentioned in II. So, II also follows.- 9. Statement: Should there be reservation in Government jobs for candidates from single child family?
Arguments:
- No. This is not advisable as the jobs should be offered to only deserving candidates without any reservation for a particular group.
- Yes. This will help reduce the growing population in India as the parents will be encouraged to adopt single child norm.
Options- A. Only argument I is strong
- B. Only argument II is strong
- C. Either I or II is strong
- D. Neither I nor II is strong
- E. Both I and II are strong Discuss
Correct Answer: Neither I nor II is strong
Explanation:
The Government has already made provisions for reservation of jobs for the economically backward sections, which is a must. So, abolishing the practice of reservation altogether has no meaning. Thus, argument I is vague. Also, more reservations would lead to non-recruitment of many more deserving candidates. Besides, such a reservation, if implemented, will cater to the job requirements of only a small section of population and not a major part of it. So, argument II also does not hold strong.- 10. Statement: Whenever you have any doubt on this subject, you may refer to the book by Enn and Enn.

- There is no other book on this subject.
Options- A. Only assumption I is implicit
- B. Only assumption II is implicit
- C. Either I or II is implicit
- D. Neither I nor II is implicit
- E. Both I and II are implicit Discuss
Correct Answer: Only assumption I is implicit
Explanation:
The recommendation of the book by Enn and Enn implies that it is available. So, I is implicit. Also, the book has been referred to as a good one, but this does not mean that no other books are available on the subject. So, II is not implicit.
