Hi everyone. Let's look at our next question which of the following orders of animals is correctly sequenced based on their metabolic rates and we have different four different choices in different orders. But the animals we have we've got fly, a mouse, a frog, an elephant and a cheetah. And what we want to recall our content videos is that xo therms or cold blooded animals? Animals have a lower metabolic rate than the end of terms or warm blooded animals. So we'd want to look at which ones are which in our list. So end of terms warm blooded. And we remember that the cold blooded have a lower rate, the end of term is higher. So we've got under cold blooded, we've got fly and frog and under warm blooded mouse, elephant and cheetah. Then to sort out the rest we remember that the low the smaller the body size, the lower the metabolic rate. So when we look at this we have a fly and a frog. So the fly is going to be first and the frog second. And then when we look at our other animals we see mouse, elephant and cheetah. So our mouse will have to be third cheetah, fourth and the largest elephant, fifth. So now we just go to our choices and find the one that has them in the correct order. So first we can eliminate anything that doesn't have fly and frog first. So that eliminates choice C. And D. Which don't have fly first and then choice A. Has mouse coming right after fly. So that takes out A. And we can check Choice B has indeed the correct order of fly frog, mouse, cheetah elephant, so there's a correct answer. See you in the next video.
