Read the paragraphs below extracted from "How to give a killer presentation" by Chris Anderson (Source: Haward Business Review) and the answer the next four questions. "A little more tha a year ago, on a trip to Nairobi, Kenya, some colleagues and I met a 12 year-old Masai boy named Richard Turere, who told us a fascinating story. His Family raises livestock on the edge of a vastion park, and one of the biggest challenges is protecting the animals form lions - especially at night Richard had noticed that placing lamps in a field didn't deter lion attacks, but he'd been interested in electronics, teaching himself by for example, taking apart his parent's radio. He used that experience to devise a system of lights that would turn on and off in sequence - using solar panels, a car battery an a motorcycle indicator box - and thereby create a sense of movement that he hoped would scare off the lions. He installed the lights, and the lions stopped attacking. Soon villages elsewhere in Kenya began installing Richard's "lion lights". The story was inspiring and worthy of the broader audience that our TED conference could offer, but on the surface, Richard seemed an unlikely candidate to give a TED talk. He was painfully shy. His English was halting. When he tried to describe his invention, the sentences tumbled out incoherently. And frankly, it was hard to imagine a pretenager standing on a stage in front of 1,400 people accostumed to hearing from polished speakers such as Bill Gates, Sir teen Robinson, and Jill Bolte Taylor. But Richard's story was so compelling that we invited him to speak. In the months before the 2013 conference, we worked with him to frame his story - to find the right place to begin, and to develop a succint and logical arc of events. On the back of this inventation Richard had won a scholarship to one of Kenya's best schools, and there he had the dance to pratice the talk several times in front of a live audience. It was critical that he build his confidence to the point where is personally could shine through whe he finally gave his talk at TED, in long beach, you could tell he was nervous, but that only made him more engaging - people were hanging on his every word. The confidence was there, and every time Richard smiled, the audience melted when be finished, the response was instanteneous: a sustained stading avation. Based on their experience, I am convinced that giving a good talk is highly coachable. In a matter of hours, a speaker's content and delivery can be transformed from muddled to mesmerizing. And while my team's experience has focused on TED's 18 minutes or shorter format the lessons we've learned are rurely useful to others presenters - whether it's a CEO doing an IPO road show, a brand manager unvelling a new product or start-up pitching to VCs." 1) According to text about presentation, Richard received some coaching and only the made his presentation at TED Long Beach.
