Statement : is a sentence (set of words) that is used to make a claim that is either true of false. Explain your answer: ollie is sound asleep = this is a statement because it is a sentence used to make a claim and it"s capable of being true or false, shut the door. This is a command and is not capable of being true or false: winter is coming. Statement because it is a sentence making a claim and capable of being true or false. Two laws of logic : the law of non-contradiction : this law states that it is impossible for both a proposition and its negation to be true at the same time. One cannot assert both p and not-p at the same time.
