It is basically repeating something you/they already said <span />
Answer and Explanation:
1. The words that describe the style of this essay are: descriptive and narrative. Since the author narrates the memories he has with his grandfather and grandmother, as well as describing how his grandfather loved scary tales and how it taught him to love that kind of story too.
2. Some words and phrases that help to establish this style are: "used", "I would hear", "Grama would say". This is because the words written in the past tense reinforce the idea of narrating memories, while the description of what the grandmother would do, reform the meaning of descriptive text.
4. The use of the word "rug" shows how memories are influenced by curious and intriguing things, because it is this word that makes the author remember that particular moment.
Efficient means someone who is working in a well-organized way and plans things well. So think of what a character would do being "well-organized" "well-planned" ...etc.
