VII. Read this passage carefully and then choose the best answer to the questions below (1.0 point)
Over the past 600 years, English has grown from a language of few speakers to become the dominant language of
international communication. English as we know it today emerged around 1350, after having incorporated many
elements of French that were introduced following the Norman invasion of 1066. Until the 1600s, English was, for the
most part, spoken only in England and had not extended even as far as Wales, Scotland or Ireland. However, during the
course of the next two centuries, English began to spread around the globe as a result of exploration, trade (including
slave trade), colonization, and missionary work. Thus, small enclaves of English speakers became established and
grew in various parts of the world. As these communities proliferated, English gradually became the primary
language of international business, banking and diplomacy.
Currently, about 80 percent of the information stored on computer systems worldwide is in English. Two-thirds of
the world's science writing is in English, and English is the main language of technology, advertising, media,
international airports, and air traffic controllers. Today there are more than 700 million English users in the world, and
over half of these are nonnative speakers, constituting the largest number of nonnative users than any other language

in the world.
