Question: How old do you have to be to purchase alcohol in the place where Uncle Tom's Cabin takes place?

full_context: Document 1: Uncle Tom's Cabin: The book opens with a Kentucky farmer named Arthur Shelby facing the loss of his farm because of debts. Even though he and his wife Emily Shelby believe that they have a benevolent relationship with their slaves, Shelby decides to raise the needed funds by selling two of them -- Uncle Tom, a middle - aged man with a wife and children, and Harry, the son of Emily Shelby's maid Eliza -- to a slave trader. Emily Shelby is averse to this idea because she had promised her maid that her child would never be sold; Emily's son, George Shelby, hates to see Tom go because he sees the man as his friend and mentor.
Document 2: Alcohol laws of Kentucky: Another inconsistency involves the difference between legal ages for buying and selling alcoholic beverages. The legal age for purchase is 21, as in all U.S. states. However, the legal age for selling or serving alcoholic beverages in a licensed establishment is 20. In the case of packaged beer, the legal selling age is 18, as long as the person is supervised by someone who is at least 20.
Document 3: Legal drinking age: The minimum age to purchase and consume varies, but the most common age is 18 years. However in North America the age limits varies between 18 and 21 years of age.

In Canada each province can decide which minimum age limit is to be set to buy or consume alcohol. Most provinces have a minimum age of 19 years, while Alberta, Manitoba and Quebec have set a minimum age of 18 years. In South America all countries have set a minimum purchase age of 18 years, except for Guyana where minors aged 16 or 17 may consume a glass of beer, wine or cider in a restaurant provided they buy a meal, and Paraguay the only country with a minimum legal purchase and drinking age of 20 years.

Document 6: Anne with an E: In the late 19th century, brother and sister Matthew and Marilla Cuthbert, both in their old age, decide to take on an orphan boy to help out around their ancestral farm of Green Gables, on the outskirts of the town of Avonlea, on Prince Edward Island. When Matthew goes to pick the child up at the railway station, he finds not a boy, but a high - spirited and talkative girl, Anne Shirley. At first, the Cuthberts are inclined to send her back, particularly after Marilla's brooch goes missing, and Anne, in despair, runs away. The family reconciles and Anne settles in her new home. Upon starting school, Anne once again displays boundless enthusiasm which is nevertheless easily turned into despair when things go wrong, which they often do. Slowly, her ebullient nature wins over those around her.

Document 12: Uncle Tom's Cabin: Uncle Tom's Cabin; or, Life Among the Lowly, is an anti-slavery novel by American author Harriet Beecher Stowe. Published in 1852, the novel had a profound effect on attitudes toward African Americans and slavery in the U.S. and is said to have "helped lay the groundwork for the Civil War".Stowe, a Connecticut-born teacher at the Hartford Female Seminary and an active abolitionist, featured the character of Uncle Tom, a long-suffering black slave around whom the stories of other characters revolve. The sentimental novel depicts the reality of slavery while also asserting that Christian love can overcome something as destructive as enslavement of fellow human beings.Uncle Tom's Cabin was the best-selling novel of the 19th century and the second best-selling book of that century, following the Bible.

Document 15: U.S. history of alcohol minimum purchase age by state: Contrary to popular belief, since the National Minimum Drinking Age Act of 1984, not all states specifically prohibit minors' and young adults' consumption of alcohol in private settings.

As of January 1, 2007, 14 states and the District of Columbia ban underage consumption outright, 19 states do not specifically ban underage consumption outright, and 17 states have family member or location exceptions to their underage consumption laws. Federal law explicitly provides for religious, medical, employment and private club possession exceptions; as of 2005, 31 states have family member or location exceptions to their underage possession laws.
