The missing clue

"The voice was that of an Oracle, the form, like that of a genie. It was addressing the world:

"Today, if you give me word that you will drop your weapons, and end all kinds of wars amongst yourselves, tomorrow I will take the virus away."

No country responded. Everyone was expecting the other country to take the lead. There was no leader.

After some time, one person stood up. All eyes immediately turned towards the person; all were eager to listen to the voice that said to the genie, "thank you, but we can do it ourselves."

The genie disappeared at once. 

"This is our leader. Yes, we can do it ourselves," thousand voices cried. 

Everyone was smiling, cheering each other up.""

The professor said to the students, 

"Now children, this is the flash and, you are to come up with your observations. One by one. And the monitor will write them down." "Here," the professor gave the pen to the monitor and said, "write down the points on the PPT in sequential structure."

To the students, the professor said, "feel free to say anything that comes to mind; remember, no observation is stupid."

The monitor started writing.

1. In which language was the genie speaking?

The class burst into laughter.

2. How did... 

Fully animated, the class went on like this. The professor was very happy with the participation, but sad too. 

No one had a clue as to what they were missing.
