What's the difference between "active standby current" and "standby current" in memory?

I don't remember the name of the steamer. The woman sold me to another woman. I had to work as cook, and nurse her little bound-footed child, who was strapped to my back to carry. The child I carried was 9 years old; and I was 11. My mistress was very cruel. Often she took off all my clothes, laid me on a bench and beat me with a rattan until I was black all over. Then she said: 'I will get rid of you and sell you.' The keeper of a brothel came to buy me, and look me over to see how much I was worth. A Chinaman living next door, knowing how I was treated and that I was going to be put in a brothel, when I saw him in the passageway, asked me if I wished to come to the Mission, and I said 'Yes.' My mistress had gone out into the next room, leaving her daughter and another slave girl in the room. I said I would go at once, and he brought me. I am very glad to live here and lead a good life."

No. 3. The rescuer was requested to meet a girl at the corner of Stockton and Jackson streets. She did so. K---- Y---
