The correct answer is option letter D. Taken from the novel “Heart of a Samurai” by Margi Preus (2010), the words that best help the reader imagine the sounds on the boat are “roar” and “flapping”. The word “roar” means that something makes a continuous, very loud noise and the word “flapping” means that something moves quickly up and down. Moreover, these words are accompanied by phrases that help grasp the meaning: roaring “like a dragon”/ flapping “like a bird”. The pronunciation of these words sounds like the actual sounds they represent. In fact, using words that imitate the natural sound of a thing is a technique called onomatopoeia. This technique is used to create a strong mental image in the narration, like it was done in this excerpt.
