[EX Q]: 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.

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
[EX A]: B

[EX Q]: Article: There are many differences between British English and American English.I used to teach a course about the differences between the two.We speak English on both sides of the Atlantic Ocean but we have many differences in our common language.We have examples of the same words having very d ifferent meanings,differing spellings of the same words as well as completely different words for the same things.Here are some examples. A cookie in the US is called a biscuit in the UK.A biscuit in the US is a small cake in the UK.Crisps in the UK,are known as chips,but we British people eat a plate of chips that you call fries in the US.In the UK,a pie can be made from either meat or fruit,while in the US pies are normally made from fruit;pot pies are made from meat.Most things are measured in grams and kilograms in the US,not pounds and ounces. One very obvious difference is the side of the road we each choose to drive on.Petrol in the UK is gas in the US.The place where we fill up our cars,in the UK,is a garage;while in the US,it's a gas station.The term garage is also used as a place to store your car next to or close by your house.In the UK we call a lorry what is known as a truck in the US. An elevator in the US is called a lift here,and the first floor in the US,is calle d the ground floor here,so many visitors get off on the wrong floor in British hotels. I could continue with this. There are countless examples of differences within our one shared language.With so many differences,no wonder it's hard to understand each other well.

Options: (A) vocabulary (B) grammar (C) sound (D) spelling
[EX A]: A
