Based On The Graph Below, Which Of The Following Statements Is Most Accurate? A. Prior To 33 Days The Population Of Medium Aliens Was Decreasing.

Video Transcript

we have a graph and we need to say which of these statements is most accurate. We've got a Prior to 33 days. When media population, medium aliens was decreasing After 33 days. The population of the ancient aliens was decreasing C after 33 days none of them changed form. Woody after 33 days, the number of total aliens in each state is unchanged. Okay, so we have the graph. I'm going to start by looking just at the medium aliens because there's two questions about them. So if I draw up the medium alien graph does goes up and then it becomes steady. So let's look at A. And B. Prior to 33 days. Was it decreasing? Know it was going up After 33 days. Was it decreasing? No, it was staying steady. So we've got C and D. And if we look at the other two types of alien here, so we have a medium. We have and there's one going like this and another one going like This. So after his 33 day point, all of them have unchanged numbers. Does that mean none of them are changing form? What does it mean that the total number of aliens in each state is unchanged? The answer is C. And not? See what? Why not see what's wrong with it? Well, this doesn't necessarily mean none of them changed full. It's possible. But there is another way this could happen. So if you imagine there are these three forms and aliens are going between them, Well, it's entirely possible that at this point, Say two Aliens go this way and to go this way, and you would still get this resort where the number is unchanged, but they're changing form. It's just that the total number of aliens in each state is unchanged, So this kind of behavior is why C might not be an accurate statement.
