单项选择题
A young woman rode with her new husband in a wagon（四轮马车）.They came to a log cabin（小木屋）.The man shouted and a little boy came running out of the cabin.Sarah,the young woman,got down from the wagon,opened wide her arms and heldthe boy close.
"Hello,Abe Lincoln,"she said."I think we′ll be good friends."
The new mother with the smiling face went to work at once.She washed Abe and hissister and tidied（弄整齐）their hair.And that night she threw away the boy′s mattress（床垫）of leaves and gave him a soft mattress and enough blankets to keephim warm at night.
Sarah wove cloth and made new shirts for Abe.She made him new deerskin trousers and even deerskin shoes.
Maybe,if she hadn′t come to the cabin,he wouldn′t have lived to be a man.When Abe′s father told him not to go to school any more and help on the farm,Sarah took Abe′s part against his father.Abe would rather read than eat,and when hisfather told him to stop,Sarah said,"Let the boy read."
In 1830 the day came when Abe would leave home to work in New Salem.For the last time she had taken Abe′s part against his father.For the last time she had kept the cabin quiet so that Abe could read.More than twenty years later,when Abe,who had then become famous,was going to make a speech in a nearby town,Sarah went there just to watch him.In the crowd she tried to make herself small,but he saw her,and in front of everybody,got out of his carriage and went overand put his arms around her and kissed her.Yes,that was her Abe.
"Heloved me truly,"she said later.
Which of the following is not true?
A.TheyoungwomaninthewagonwasAbe'snewmother
B.ThemaninthewagonwasAbe'snewfather
C.Thelittleboywastheyoungwoman'snewson
D.ThelittleboyrunningoutofthecabinwasAbe
