text: Althought the author did a good job with presenting the risk and fixing those risk but he did not quite express how it would all be worth it in the end. But in the end the prompt was about how studying Venus is a worthy pursuit and there was not a lot of content on that in this piece of writing. So the author did not support this idea very well.                         I think we should use that technology to see students emotions. we would be abel to see how they really feel in that just one picture. we could see how they felt towards someone. when they lying too, becuase some students dont like to show or describe how they feel. not just on students we should use it on we should use it on friends and family too. we need to know how to help people if they upstet to cheer them up, or if there happy we need to know what made them happy.
