Final answer:
The statement 'Do not pass go' is not a proposition because it is an imperative sentence and cannot be true or false. Therefore, the answer is true, confirming that it isn't a proposition.
Step-by-step explanation:
The student has asked whether the statement 'Do not pass go' is a proposition. To determine this, we must know that a proposition must be able to have a truth value; that is, it must be capable of being true or false. However, the phrase 'Do not pass go' is an imperative sentence and hence, it does not declare or describe something that can be true or false. Therefore, the given statement is not a proposition, and the correct answer would be true.
It's important to understand the law of noncontradiction, which states that a statement and its negation cannot both be true at the same time. A negation of a statement is the denial of the original statement, and together, a statement and its negation form a contradiction. However, since the given statement 'Do not pass go' can not have a truth value, it cannot be negated in the context of forming a contradiction as per the law of noncontradiction.
