Question: How many congressional districts are there in the state where Dorothy lived in The Wizard of Oz?

full_context: Document 1: United States House of Representatives: The composition and powers of the House are established by Article One of the United States Constitution. The House is composed of Representatives who sit in congressional districts that are allocated to each of the 50 states on a basis of population as measured by the U.S. Census, with each district entitled to one representative. Since its inception in 1789, all Representatives have been directly elected. The total number of voting representatives is fixed by law at 435. As of the 2010 Census, the largest delegation is that of California, with fifty - three representatives. Seven states have the smallest delegation possible, a single representative: Alaska, Delaware, Montana, North Dakota, South Dakota, Vermont, and Wyoming.
Document 2: Dorothy Gale: In the Oz books, Dorothy is an orphan raised by her aunt and uncle in the bleak landscape of a Kansas farm. Whether Aunt Em or Uncle Henry is Dorothy's blood relative remains unclear. Uncle Henry makes reference to Dorothy's mother in The Emerald City of Oz, possibly an indication that Henry is Dorothy's blood relative. (It is also possible that ``Aunt ''and`` Uncle'' are affectionate terms of a foster family and that Dorothy is not related to either of them, although Zeb in Dorothy and the Wizard in Oz claims to be Dorothy's second cousin, related through Aunt Em. Little mention is made of what happened to Dorothy's birth parents, other than a passing reference to her mother being dead.) Along with her small black dog, Toto, Dorothy is swept away by a tornado to the Land of Oz and, much like Alice of Alice's Adventures in Wonderland, they enter an alternative world filled with talking creatures. In many of the Oz books, Dorothy is the main heroine of the story. She is often seen with her best friend and the ruler of Oz, Princess Ozma. Her trademark blue and white gingham dress is admired by the Munchkins because blue is their favorite color and white is worn only by good witches and sorceresses, which indicates to them that Dorothy is a good witch.
Document 3: Political interpretations of The Wonderful Wizard of Oz: Littlefield's knowledge of the 1890s was thin, and he made numerous errors, but since his article was published, scholars in history, political science, and economics have asserted that the images and characters used by Baum closely resemble political images that were well known in the 1890s. Quentin Taylor, for example, claimed that many of the events and characters of the book resemble the actual political personalities, events and ideas of the 1890s. Dorothy -- naïve, young and simple -- represents the American people. She is Everyman, led astray and seeking the way back home. Moreover, following the road of gold leads eventually only to the Emerald City, which may symbolize the fraudulent world of greenback paper money that only pretends to have value. It is ruled by a scheming politician (the Wizard) who uses publicity devices and tricks to fool the people (and even the Good Witches) into believing he is benevolent, wise, and powerful when really he is a selfish, evil humbug. He sends Dorothy into severe danger hoping she will rid him of his enemy the Wicked Witch of the West. He is powerless and, as he admits to Dorothy, ``I'm a very bad Wizard ''.

Document 6: United States Congress: The members of the House of Representatives serve two - year terms representing the people of a single constituency, known as a ``district ''.

Each state, regardless of population or size, has two senators. Currently, there are 100 senators representing the 50 states.

Document 7: The Wonderful Wizard of Oz: When Dorothy and her friends meet the Wizard of Oz again, Toto tips over a screen in a corner of the throne room that reveals the Wizard. He sadly explains he is a humbug -- an ordinary old man who, by a hot air balloon, came to Oz long ago from Omaha. The Wizard provides the Scarecrow with a head full of bran, pins, and needles (``a lot of bran - new brains ''), the Tin Woodman with a silk heart stuffed with sawdust, and the Cowardly Lion a potion of`` courage''. Their faith in the Wizard's power gives these items a focus for their desires. The Wizard decides to take Dorothy and Toto home and leave the Emerald City. At the send - off, he appoints the Scarecrow to rule in his stead, which he agrees to do after Dorothy returns to Kansas. Toto chases a kitten in the crowd and Dorothy goes after him, but the tethers of the balloon break and the Wizard floats away.

Document 11: Laura Ingalls Wilder: In 1894, the Wilder family moved to Mansfield, Missouri, and used their savings to make the down payment on an undeveloped property just outside town. They named the place Rocky Ridge Farm and moved into a ramshackle log cabin. At first, Wilder and her husband earned income only from wagon loads of fire wood they would sell in town for 50 cents. Financial security came slowly. Apple trees they planted did not bear fruit for seven years. Wilder's parents - in - law visited around that time and gave them the deed to the house they had been renting in Mansfield, which was the economic boost Wilder's family needed. They then added to the property outside town, and eventually accrued nearly 200 acres (80.9 hectares). Around 1910, they sold the house in town, moved back to the farm, and completed the farmhouse with the proceeds. What began as about 40 acres (16.2 hectares) of thickly wooded, stone - covered hillside with a windowless log cabin became in 20 years a relatively prosperous poultry, dairy, and fruit farm, and a 10 - room farmhouse.

Document 13: List of Oz characters (created by Baum): Dorothy Gale is the main character and adolescent protagonist in The Wonderful Wizard of Oz (1900), and the several other sequel Oz books. She is depicted as being a very young, heroic and sweet tempered orphan girl from a small farm on the prairies of Kansas. Baum never reveals Dorothy's age, but she is thought to be no older than twelve years old. In appearance she is described as having chubby little hands, a round rosy face, big earnest eyes filled with awe and a merry laugh. She has a small pet dog she calls Toto, and loves dearly. After her first adventure in the Land of Oz, she returns to Kansas via the charmed Silver Shoes, (Ruby Slippers in the classic MGM musical of 1939) she obtained while there but lost between worlds when she was teleported back. Not much later, she unexpectedly returns to Oz again, thus having several more adventures before permanently settling there as an official princess of Oz in the book The Emerald City of Oz (1910).
Document 14: Yellow brick road: The road is first introduced in the third chapter of The Wonderful Wizard of Oz. The road begins in the heart of the eastern quadrant called Munchkin Country in the Land of Oz. It functions as a guideline that leads all who follow it, to the road's ultimate destination -- the imperial capital of Oz called Emerald City that is located in the exact center of the entire continent. In the book, the novel's main protagonist, Dorothy, is forced to search for the road before she can begin her quest to seek the Wizard. This is because the cyclone from Kansas did not release her farmhouse closely near it as it did in the various film adaptations. After the council with the native Munchkins and their dear friend the Good Witch of the North, Dorothy begins looking for it and sees many pathways and roads nearby, (all of which lead in various directions). Thankfully it does n't take her too long to spot the one paved with bright yellow bricks.
Document 15: Dorothy Gale: In later novels, the Land of Oz steadily becomes more familiar to her than her homeland of Kansas. Indeed, Dorothy eventually goes to live in an apartment in the Emerald City's palace but only after her Aunt Em and Uncle Henry have settled in a farmhouse on its outskirts, unable to pay the mortgage on their house in Kansas. Dorothy's best friend Princess Ozma, ruler of Oz, officially makes her a princess of Oz later in the novels.
