Rate the following essay on its writing, argument, and language skills:
The technology emotional expression is helpful because now that we have that we can look back at old pictures and wonder. What was Abraham so mad about? Or why was George Washington so happy but sad about? This experiment can change the way we look at history.

This experiment can help us more understand the past. Like the Mona Lisa nobody knew she had all that emotion in her when she took that picture. Because her smile was so big it stood out. When really she was happy but had all these other emotions in her that we didn't know she had.

This can help students by doing projects on the person they picked and they can research a pciture and then use the experiment to discover their emotions at the time. This new experiment can change alot of wrong discovers that were made in the past. Now we can know more with the new emotional expressions.

It can also be used to tell if some one is lying or telling the truth. It's so many celebrities that put on a fake smile to the press when really there's something going on behind closed doors. This new thing can help people that have problems because we can see how they really feel. Say if we used this in the school year book and we use it on a student that does abd in school or is always in trouble. we could actually look at the emotional expression and see that he has a lot of anger in him and could cause harm.

I'm glad that this was made cause it can make a lot of change. It can help in schools, businesses, police departments, etc. It's a lot of people out here that put on a fake smile but would really go and shoot up a school or could commit suicide. But now that we have this we can stop thought incidents from happeing.
