Question

Which of the following sentences is not a statement?

• A. $9$ is less than $7$
• B. The sun is a star
• C. There is no rain without clouds
• D. Mathematics is fun

Answer 1

Answer: (D)

(a) ${}^{\prime \prime }9$ is less than $7^{\prime \prime }$ is a false sentence because $9$ is greater than $7$. So it is a statement.
(b) It is scientifically established fact that sun is a star, therefore, this sentence is always true. Hence "The sun is a star" is a statement.
(c) It is a scientifically established natural phenomenon that clouds are formed before it rains, this sentence is always true and hence it is a statement.
(d) The sentence "Mathematics is fun" is subjective in the sense that for those who like mathematics, it may be fun but for others it may not be, which means that the sentence "Mathematics is fun" is not always true. So it is not a statement.
