What is the name for a declarative statement that is either true or false, but not both?
Difficulty: Easy
About this MCQ
This Easy Discrete Mathematics MCQ checks one syllabus fact.
The question is: “What is the name for a declarative statement that is either true or false, but not both?”
The accepted answer is C. Proposition. Proposition is the fact required by “What is the name for a declarative statement that is either true or false, but not both” (option C). Option A (“Relation”) does not match the stem; it is a near-miss used to catch incomplete recall of Proposition. Option B (“Recurrence relation”) does not match the stem; it is a near-miss used to catch incomplete recall of Proposition. Remaining alternatives (Mathematical induction) fall outside the same rule and should be eliminated once Proposition is identified. Discrete Mathematics questions of this type reward precise definitions rather than approximate associations. Discrete Mathematics recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
- A. Relation
Why not A: “Relation” is not correct. The accepted answer is C. Proposition. Proposition is the fact required by “What is the name for a declarative statement that is either true or false, but not both” (option C). Option A (“Relation”) does not match the s
- B. Recurrence relation
Why not B: “Recurrence relation” is not correct. The accepted answer is C. Proposition. Proposition is the fact required by “What is the name for a declarative statement that is either true or false, but not both” (option C). Option A (“Relation”) does not match the s
- C. Proposition ✓
- D. Mathematical induction
Why not D: “Mathematical induction” is not correct. The accepted answer is C. Proposition. Proposition is the fact required by “What is the name for a declarative statement that is either true or false, but not both” (option C). Option A (“Relation”) does not match the s
Correct answer
C. Proposition
Explanation
Proposition is the fact required by “What is the name for a declarative statement that is either true or false, but not both” (option C). Option A (“Relation”) does not match the stem; it is a near-miss used to catch incomplete recall of Proposition. Option B (“Recurrence relation”) does not match the stem; it is a near-miss used to catch incomplete recall of Proposition. Remaining alternatives (Mathematical induction) fall outside the same rule and should be eliminated once Proposition is identified. Discrete Mathematics questions of this type reward precise definitions rather than approximate associations. Discrete Mathematics recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
