Answer:
a) false
b) true
c) true
d) true
Step-by-step explanation:
A statement is an assertion that something is or is not the case. It is a kind of sentence that is either true or false. However, non-statements are sentences that cannot be either true or false. For example, in the sentence "Welcome to America" if someone answers "true" or "false", it will not make sense with the context, hence the response to the sentence is neither true nor false, it is hence not a statement. In our example, the options; b, c and d are all statements, while 'a' is not a statement, but rather a question, and doesn't state is something is or is not the case.
