Answer:
He is using a technique called "Think, Pair, Share".
Explanation:
"Think, Pair, Share" is a discourse technique widely used as a learning method that can be adapted to different scenarios, and can even be adopted during a debate or speech.
This technique insists that for an argument to be effective, it must first be thought, reasoned and researched by an individual. The second one, called "pair", states that the individual must gather arguments and references that prove what he researched and what he is defending. Last, but not least, the individual must hold everything that I gather and defend his position on the subject, just as Kyan did. That's because Kyan, after thinking and researching his topic, found an article in a scientific magazine that confirms his argument about the benefits of nuclear energy.
