Since the middle term 'tigers' is not distributed even once in the premises, no definite conclusion follows. However, I and II involve only the extreme terms and form a complementary pair. So, either I or II follows.
4. Statement: If he is intelligent, he will pass the examination.
The statement mentions that he will pass if he is intelligent. So, I is implicit. Further, this means that it is not necessary that he will pass. So, II is not implicit.
5. Statement: "Television X - the neighbour's envy, the owner's pride" - A T.V. advertisement.
Assumptions:
Catchy slogans appeal to people.
People are envious of their neighbours superior possessions.
Clearly, both I and II directly follow from the statement. Also, it is clear that people wish to buy a thing which they can be proud of. So, III is not implicit.
6. Statement: The car dealer found that there was a tremendous response for the new XYZ's car-booking with long queues of people complaining about the duration of business hours and arrangements.
Courses of Action:
People should make their arrangement of lunch and snacks while going for car XYZ's booking and be ready to spend several hours.
Arrangement should be made for more booking desks and increased business hours to serve more people in less time.
Seeing the tremendous response, the dealer must make suitable arrangements and deploy more personnel to take care of customers so that they don't have to wait excessively long for booking. So, only course II follows.
8. Statements: The Prime Minister emphatically stated that his government will make every possible effort for the upliftment of poor farmers and farmhands.
Conclusions:
Except poor farmers and farmhands, all others have got benefits of fruits of development.
No serious efforts have been made in the past for upliftment of any section of the society.
Since both premises are particular, no definite conclusion follows. However, I is the converse of second premise, while II is the converse of the first premise. So, both of them hold.
10. Statement: There is a considerable increase in the number of persons affected by water-borne diseases during monsoon period.
Courses of Action:
The question should be raised in the Legislative Assembly.
The Government should disseminate adequate information regarding the pure drinking water to people.
All the hospitals in the city should be equipped properly for the treatment of patients during monsoon period.
Any aspect of health has two factors to tackle with - prevention and treatment. Prevention includes creating awareness among people, and treatment includes providing adequate medical facilities. So, both II and III follow.
