Read the passage carefully and choose the correct answer.
Almost every language in the world has dialects and American English is no exception. At the present time there is an interesting study which is on American speech habits. This study has shown that different words are frequently used in different parts of the country to denote the same thing. For example, in the east, Americans use the word "soda" to denote a soft drink. In some parts of the west, a soft drink is "tonic". Such differences are usually a source of conversation and sometimes misunderstanding happens.
Speech and life all over the world have often changed. New words are being used when new discoveries are made and new concepts are formed. Usage determines what is correct and what is incorrect. Fifty years ago, it was incorrect to say "It's me." But today it is acceptable simply because most Americans say that instead of "It's I." People change, so language changes. What is wrong today may be right tomorrow.
