Read the text carefully and then choose the correct answer:
English has had a long tradition of borrowing words from other languages. This tradition began with the conquest of Britain by the Norman- French in 1066 because the conquerors established themselves as rules, their dialect of French became the language of the aristocracy , of government, and of education. During this period, many French words came into the English language. Another strong influx of vocabulary came from Latin, which was the language of the church. Today, those words derived from French and Latin, though still identifiable, are not thought of as foreign by English speakers. Tradition, language and conquest are words that come to us from this tradition.
	The British colonial era, which began in the early 17th century, brought English speakers into contact with many other languages. In North America, words from the Native American peoples quickly found their ways into the language. Examples include moccasin ( a kind of soft shoe), squash ( a vegetable ).
The presence of Spanish colonies in North America led to the adoption of numerous Spanish's words, such as siesta ( a nap ) and tortilla ( a flat thin pancake ). Asian languages also make contributions. For example, the world pyjamas comes from a Hindu word, khaki comes from Urdu, and ketchup was borrowed from Chinese. Words from African languages, too, made their ways into English when African slaves served in the United States. The result of all of this absorption of new words is a very rich vocabulary that allows users of English to express subtlety of meaning through their choice of words.
