Answer the following question given this paragraph: Note the word science in that last sentence. Earth Science is a science, or maybe it's made up of a lot of sciences. But what is science? Most people think of science as a bunch of knowledge. And it is. But science is also a way of knowing things. It's different from other ways of knowing because it is based on a method that relies on observations and data. Science can't say how many angels can dance on the end of a pin because that question can't be tested. In fact, science can't even say if there are such things as angels for the same reason. For something to be science, it must be testable. And scientists are the people who do those tests. Q: A fact or question is only considered science if it has what property? Choices: - it is interesting - it is mineral - it is believable - it is testable A:
A:
it is testable
