The state of Colorado runs an ad which shows an obviously scared third grader getting ready to go on stage for his first public stage appearance. He is dressed as a carrot. The ad tells the reader that being a third grader is much more stressful than we remember and causes us to feel great sympathy for the child dressed in the ridiculous costume. The tag line at the end of the ad reads, "Your kids need a carefree Colorado vacation as much as you do." This is an example of a technique.

Dramatisation Technique.

Explanation:

Dramatisation Technique is a collective method of teaching that involves teaching using the techniques of dram such as story-telling. This technique is used in classrooms to make children gain a deep insight into their lessons.

In the given case, the ad used this dramatisation technique to convey a message to their reader that to relieve from the stress of life not just kids need a Carefree vacation but the parents and elders too. This message was conveyed by dramatising a situation of a third-grader stressful scenario.

So, the correct answer is the dramatisation technique.
