    c) There are no black flies in Maine - > False

    e) The moon is made of green cheese - > False

    Explanation:

    A proposition is a statement that poses an idea that can be True or False.

    Do not pass go, is not a proposition is an order, and there is not an answer to that statement. What time is it? Is not a proposition is a question and it's response goes beyond True or False. There are no black flies in Maine is indeed a proposition because is a statement that can either be True or False. 4 + x = 5 is not a proposition because is a statement with an infinite number of answers, in contrast, 4 + 1 = 5 is a proposition because is either True or False. The moon is made of green cheese is a proposition because is a statement that can either be True or False. 2 n ≥ 100 is not a proposition because is a statement with an infinity number of answer and is not clear whether is True or False, in contrast, 2 ≥ 100 is a proposition because is either True or False.
