Example Input: Article: American schoolchildren often wear uniforms if they attend religious or other private schools. Most public schools do not require uniforms. But over the last ten years or so, more of them have moved in that direction, including high schools. Students may have to wear a specially purchased uniform. Or they may just have to dress alike~for example, white shirts and dark color1ed pants or skirts. Even schools that do not require uniforms generally have a dress code or other rules about what they consider acceptable. Policies commonly ban clothing that shows offensive images or words, or simply too much skin. Items like hats may be not permitted because ,for example, different color1s may be connected with violent gangs. Some parents like the idea of uniforms. They say it means they do not have to spend as much on clothing for their kids. Others, though, argue that uniforms represent an unnecessary cost There are also debates about whether uniforms or other dress policies break civil rights. Students and parents have taken legal action against school dress requirements. Just last week, a judge blocked a middle school in Napa, California, from enforcing a dress code unless families have a way out of it The American Civil Liberties Union of Northern California brought the case for the families of several students who werfe punished Most attention centered on a girl who wore socks with the Tigger character from Winnie the PooK The school said its clothing policy, including no pictures of any kind, was needed to control a growing problem with gangs. The families argued that the policy went against free speech rights as guaranteed by the United States and California constitutions. The United States Supreme Court says student expression is protected as long as it does not harm the work and discipline of a school.

Example Input: Article: I was born in Tuckahoe,Talbot Country,Maryland. I have no accurate knowledge of my age,never having seen any record containing it. By far the larger part of the slaves know as little of their ages as horses know of theirs,and it is the wish of most masters within my knowledge to keep their slaves thus ignorant .I do not remember having ever met a slave who could tell of his birthday. They seldom come nearer to _ than plantingtime,harvesting,springtime,or falltime. A lack of information concerning my own was a source of unhappiness to me even during childhood. The white children could tell their ages,but I could not tell. Why the same right ought to be taken away from me!I was not allowed to ask my master about it. He considered all such questions on the part of a slave improper and impolite. The nearest estimate I can live makes me now between twentyseven and twentyeight years of age. I come to this,from hearing my master say,some time during 1835,I was about seventeen years old. My mother was named Harriet Bailey. She was the daughter of Isaac and Betsey Bailey,both colored,and quite dark. My father was a white man. The opinion was also whispered that my master was my father;but of the correctness of this opinion,I know nothing and I have no means to know. My mother and I were separated when I was but an infant--before I knew her as my mother. It is a common custom,in the part of Maryland from which I ran away,to part children from their mothers at a very early age. Frequently,before the child has reached its twelfth month,its mother is taken from it,and hired out on some farm a considerable distance off,and the child is placed under the care of an older woman,too old for field labor.
Question: It can be learned from the text that _ .
Options: (A) the slaves forgot the exact time when they were born (B) the writer didn't know whether his master was his father (C) the writer was about twentyseven years old in 1835 (D) the writer's mother left him as soon as he was born
