After breakfast Dad always announced: “Go ahead everyone.Ill take care of the dishes！” With that my mother disappeared into the folds of the Sunday paper. Off_came_the_suit_coat_he_had_worn_to_church_that_morning._Up_went_the_shirtsleeves._On_went_that_apron. For the next hour Dad did the dishes, singing songs like“Who Put the Chow in Mrs. Murphys Chowder”？I suppose it was strange for a father to wear an aproneven one with race carsbut I never thought much of it until that Sunday when we walked home from church together.“Tommy”， he said，“There comes a time in every boys life when he must take on responsibilities” “Responsibilities？” I asked. “Yes. Its time you took a greater role in the household. Starting today, I want you to do the dishes on Sunday morning so your mother and I can relax.” “The dishes？” “Anything wrong with taking over the dishes？”I started to say something about a mans job, but I knew immediately that my protests would fall on deaf ears.I didnt taste a bit of breakfast that morning. My father announced to my mother, “Lets go to read the paper, honey.Our oldest son has generously offered to fill the position.”So this was what my life had come to.People often say there is a special chemistry between a father and a son. He came back into the kitchen just as I was about to storm out. In his right hand was the old apron.“I want you to have this, Tommy. Itll keep your clothes from getting wet.” And before I could do anything, he had put that apron on me. “Thanks, Son. Your mother and I appreciate this.”With that he disappeared into the Sunday paper. I looked down at the apron.It had seen better days.I could see my dad reaching for the dishes. Soon I was singing about Mrs. Murphys Chowder.16What is the main purpose of the underlined sentences in the first paragraph?ATo show the unwillingness of his father when doing dishes.BTo instruct the main steps of how his father does dishes.CTo emphasize his fathers clumsy way of doing dishes.DTo stress the enjoyment and happiness of his fathers doing dishes.17What does the underlined word “responsibilities” in the second paragraph refer to?ATaking care of the brothers.BMaking progre
