Passage 1
Questions 1 to 5 are based on the following passage.
I was bom in a pleasant old colonial house built near 1750, and bought by my grandfather sixty or seventy years ago. He joined a group of acquaintances who were engaged in the flourishing West Indian trade of that time. For many years he kept and extended his interests in shipping, building ships and buying large quantities of timber, and sending it down the river and then to the sea. The business was still in existence in my early childhood, so I came in contact with the up-country people who sold timber as well as with the sailors and shipmasters of the other side of the business. I used to linger about the busy country stores, and listen to the lively country talk.
In my grandfather’s business household，my father had taken to his book，as old people said, and gone to college and begun that devotion to the study of medicine which only ended with his life. He gave me my first and best knowledge of books by his own delight and dependence upon them, and ruled my early attempts at writing by his good taste. "Don't try to write about people and things, tell them just as they are!" How often my young ears heard these words without comprehending them! But while I was too young and thoughtless to share in an enthusiasm for Sterne or Fielding, and Smollett or Don Quixote, my mother and grandmother were leading me into the pleasant ways of Pride and Prejudice, and The Scenes of Clerical Life, and the delightful stories of Mrs. Oliphant.
When the time came that my own world of imagination was more real to me than any other, I was sometimes perplexed at my father's directing my attention to certain points of interest in the character or surroundings of our acquaintances. I cannot help believing that he recognized, long before I did myself, in what direction the current of purpose in my life was setting. Now, as I write my sketches of country life, I remember again and again the wise things he said, and the sights he made me see. I may have inherited something of my father’s knowledge of human nature, but my father never lost a chance of trying to teach me to observe. I owe a great deal to his patience with a little girl given far more to dreams than to accuracy, and with perhaps too little natural sympathy for the dreams of others.
In Paragraph 1, "the other side of the business" refers to____.
