Reference Material:
You’ve got sound receptors in your ear, and they are beautiful. We’re not going to talk about them at any length, but there’s little flappy, these little spiky things going along in your ear and they can translate vibrational energy coming from your ear, hurting your eardrum, being translated into a vibration into the fluid in your ear into a physical motion of these little receptors there into an electrical motion, into an electrical signal that goes into your ear. So, all of that, all of that’s pretty impressive stuff. We are not going to talk about the details of it, but I invite some of you who want to learn more about this, particularly MIT students I think to find receptors really quite remarkable kinds of devices.

Sample Answer:
The sound receptors are beautiful, and they have flappy and spiky things in the ear which can translate vibrational energy from the eardrum into physical motion, and then it converts into electrical motion. Finally, the fluid is changed into an electrical signal. All of those processes are impressive, and thus the speaker invited MIT students to explore the details of this remarkable device. (63 words)
