14.In the late 1920s my mother ran away from home to marry my father.Marriage,if not running away,was expected of 17-year-old girls.By the time she was 20,she had 2 children and was pregnant with a third.5 children later,I was born.And this is how I came to know my mother:she seemed a large,soft,loving-eyed woman who was rarely impatient in our home.Her quick,violent temper was on view only a few times a year,when she battled with the white landlord who had the misfortune to suggest to her that her children did not need to go to school.She made all the clothes we wore,even my brothers' overalls.She made all the towels and sheets we used. She spent the summers canning vegetables and fruits.She spent the winter evenings making quilts enough to cover all our beds.During the "working" day,she labored beside-not behind-my father in the fields.Her day began before sunup,and did not end until late at night.There was never a moment for her to sit down,undisturbed,to unravel her own private thoughts;never a time free from interruption-by work or the noisy inquiries of her many children.And yet,it is to my mother-and all our mothers who were not famous-that I went in search of the secret of what has fed that muzzled and often mutilated,but vibrant,creative spirit that the black woman has inherited,and that pops out in wild and unlikly places to this day. 问题：The goal of the narrator's research was to ( )
