Question

question 9 (1 point)
which of the following is true?
○ no two sentences express exactly the same proposition.
○ only two completely identical sentences can express the same proposition.
○ two different sentences may express exactly the same proposition.

Explanation:

To determine the correct statement, we analyze the concept of propositions and sentences. A proposition is the meaning or content of a sentence (the statement it makes). Different sentences (e.g., "John is a doctor" and "Dr. John is a medical professional" or even sentences in different languages like "La neige est blanche" and "Snow is white") can express the same proposition.

• The first option is false because, as shown, different sentences can share the same proposition.
• The second option is false because sentences don't have to be identical (they can vary in wording, language, structure) to express the same proposition.
• The third option is true as different sentences (e.g., "The cat is on the mat" and "On the mat is the cat") can convey the same proposition (the state of the cat being on the mat).

Answer:

C. Two different sentences may express exactly the same proposition.
