Final answer:
England, Britain, and Great Britain are not synonymous; England is a part of Great Britain, and Great Britain is part of the United Kingdom which also includes Scotland, Wales, and Northern Ireland.
Step-by-step explanation:
England, Britain, and Great Britain do not all refer to the same thing. The term 'England' refers specifically to the country within the United Kingdom that occupies the southern portion of the island of Great Britain. 'Britain' is an informal term that is often used to refer to the entire United Kingdom or sometimes just Great Britain. The term 'Great Britain' refers to the larger island that comprises Scotland, Wales, and England. However, this does not include Northern Ireland. The political entity known as 'Great Britain' was created in 1707 by the union of England and Scotland. The United Kingdom (UK) includes England, Scotland, Wales, and Northern Ireland.
