Input: Consider Input: Article: As a young adult, Noah Webster was a teacher. At this time, the colonies were fighting for independence from Britain. Yet the books that American children used in school all came from Britain. The books were all about British people and British places. Webster wanted books that would mean more to American children. So he wrote three books that used American examples -- a grammar book, a spelling book, and a reader. These books were very popular, and millions of them were sold. Webster was interested in changing the spellings of words. He wanted words to be spelled the way they were pronounced. For example, he thought the word "head" should be spelled "hed", and the word "laugh" should be spelled "laf". People liked Webster's suggestions. However, few words were actually changed. One group of words that were changed were words in which an unpronounced "u" followed an "o". That is why Americans write "color" and "labor", and the British write "colour" and "labour". With the money he made from his books, Webster was able to write. It was the first American English dictionary, published in 1828. Webster's dictionary had over 70000 words and gave the meaning and origin of each. To this day, Webster's work is the example that most dictionaries of American English follow.

Input: Consider Input: Article: Some people argue that the pressures on international sportsmen and sportswomen kill the essence of sport-seeking for personal excellence. Children kick a football around for fun. When they get older and play for local school teams, they become competitive but they still enjoy playing. A single person's representing his country cannot afford to think about enjoying himself; he has to think only about winning. He is responsible for an entire nation's hopes, dreams and fame. A good example is the football World Cup. Football is the world's most important sport. It is even more important now that the United States is seriously taking it up. Winning the World Cup is perhaps the greatest of international sporting success. Mention "Argentina" to someone and the chances are that he'll think of football. In a sense, winning the World Cup "put Argentina on the map". Sports fans and supporters get quite irrational about the World Cup. People in England felt that their country was somehow important after they won in 1996. Last year thousands of Scots sold their cars, and even their houses and spent all their money traveling to Argentina where the finals were played. So am I arguing that international competition kills the idea of sports? Certainly not! Do the Argentineans really believe that because eleven of their men proved that most skillful at football, their nation is in every way better than all others? Not really. But it's known that you won, and that in one way at least your country is best.
Question: What is the writer's main purpose in the passage?
Options: (A) To explain the role of sport (B) To compare Scotland with Argentina (C) To show that Argentina is better than all others. (D) To prove that football is the world's most important sport.
Output: A
