Questions no one knows the answers to (English listening exercise)

Questions no one knows the answers to (English listening exercise) Its been a while since Ive had the time to visit the Ted website and watch a video, much less make a new listening exercise using one of their videos. So it wasnt until today that I found out about a new series of Ted videos called TED-ED.According to the TED-Ed website:TED-Eds mission is to capture and amplify the voices of great educators around the world. We do this by pairing extraordinary educators with talented animators to produce a new library of curiosity-igniting videos.The animation is truly great. I think that for people learning English, it is especially helpful to see the ideas in the videos illustrated. I wish we were able to do this kind of animation with our English videos weve been making!Below youll find one of the videos that TED-ED has created to introduce this new project. The video is about questions that humans dont know the answers to, curiosity and learning. Watch the video, and below youll find an English listening exercise to go with it.
