Match List I with List II
Identify the propositions and match the followings.
LIST I
A. Exceptive proposition
B. Categorical Proposition
C. General Proposition
D. Compound propositon
LIST II
I. Ten is greater than five.
II. If the war is declared then petrol prices will go up.
III. The wicked alone are happy.
IV. All mathematicians are skilled logicians.
Choose the correct answer from the options given below:
A-III, B-I, C-IV, D-II
Each item in List I names a type of proposition and must be matched with a sentence in List II that best illustrates it.
Exceptive proposition uses a word such as 'alone' or 'only' to assert that a predicate applies to just one class, excluding all others - 'The wicked alone are happy' fits this form.
Categorical proposition makes a plain, unconditional assertion relating a subject and a predicate - 'Ten is greater than five' is a direct, unconditional assertion of this kind.
General proposition is a universal statement using a quantifier like 'all' - 'All mathematicians are skilled logicians' is a clear universal claim.
Compound proposition joins two statements with a connective such as 'if...then' - 'If the war is declared then petrol prices will go up' is a conditional (hypothetical) statement made of two component clauses.
| List I | List II |
|---|---|
| A. Exceptive proposition | III. The wicked alone are happy. |
| B. Categorical Proposition | I. Ten is greater than five. |
| C. General Proposition | IV. All mathematicians are skilled logicians. |
| D. Compound proposition | II. If the war is declared then petrol prices will go up. |
Thus the correct matching is A-III, B-I, C-IV, D-II.
