text: It can be true, but it can be false. People don't know what is going to happen next. So people have to figure out on their own. So I disagree that about using of this technology to read the emotional expressions of students in a classroom is valuable.I believe that seeking multiple opinions can help someone make a better choice, Why? Because you get more advice from people which can result for one advice from the multiple other advice's/choice's to be the best to choose, the more people you talk to the more people will relate to you when asked for advice from you and they will give you better opinions, and finally they will support you when making your final decision.
