Read the passage carefully and answer the questions given below.
Laws of nature are not commands but statements of acts. The use of the word "law" in this context is rather unfortunate. It would be better to speak of uniformities in nature. This would do away with the elementary fallacy that a law implies a law giver. If a piece of matter does not obey a law of nature, it is punished. On the contrary, we say that the law has been incorrectly started.
