Task: Question Answering
Input (English): Passage: One foggy night in Devon, Gail, a working border collie Herding dog, gives birth to a litter of three puppies, cozy in a barn on Borough Farm. As she lies quietly with her newborn litter, her father, Sir Gregory, walks inside, not realizing she had her puppies until she summons his attention and he spots them curled up next to her. She has already named two of them Storm and Drift but she thinks Sir Gregory should name the third. He looks out of the window and names her Mist after the "misty" night she was born. All the other dogs, Swift, her son Ernie, and Jake, are delighted to meet the puppies at last but Fern doesn't seem to like puppies and is not happy to be their auntie.
When the puppies realize they can finally see things, Mist looks out of a nearby window and sees a flock of sheep pass by, but does not exactly know what they are. She points them out to Storm and Drift, but by the time they come to the window, the sheep are gone. They think Mist is making it up, and they playfully tease and wrestle each other around the barn. This soon tires them out, and they slowly fall asleep side by side.
Mist seems to like the idea of working the flock more than her brother and sister. Later that day, Sir Gregory talks with Gail about how well Mist is doing compared to Storm and Drift. Gail realises it is finally time to choose which of the puppies will stay on Borough Farm to be trained as a working sheepdog, and which have to leave. One day the puppies are playing in the yard when two different families come to take Storm and Drift away. They are placed in the cars and Gail sadly watches them drive away.
Winter arrives at Borough Farm, but Fern has still not warmed up to Mist. One day Mist gets giddy and runs off into the woods; a dark place where she soon gets lost and has to be rescued by the Boss and Sir Gregory. This amuses Fern. 
Question: What are the names of the puppies that Fern does not seem to like?
Output (English): Drift.
