Answer:
They used personification to make the truck seem mean and violent.
Step-by-step explanation:
As you can see in the sentence above, the author used the adjectives "loud" and "aggressive" to characterize the truck that hit the narrator. However, a truck is an object, an inanimate being and the adjectives "tall" and "aggressive" are characteristics associated with human beings. However, when the author uses these adjectives to characterize the truck, it allows the reader to have a feeling that the truck is cruel, without manners and violent.
The personification is the figure of speech that has this ability to associate human characteristics with inanimate objects to make these objects appear in a certain way. In this case, we can say that the author used impersonation to make the truck look cruel and violent.
