Give three examples of sentence which are not statements. Give reasons for the answers.
A statement or a proposition is an assertive (or a declarative) sentence which is either true or false but not both.
Example (1) : "Who lost this watch?" is an interrogative sentence. Hence, it is not a statement.
Example (2) : The sentence : x + 2 =9 is an open sentence. Its truth value cannot be confirmed unless we are given the value of x. So, it is not a statement.
Example (3) : The sentence " May god bless you !" is an exclamatory sentence, So, it is not a statement.
