Read the following paragraph and choose the best topic sentence from the four options that follow. Write the corresponding letter of your choice on the answer sheet.Societies choose words and frame grammars to meet particular needs: to name something describe actions, and express feelings. Not all societies have the same needs, as a comparison of different languages reveals. The linguist Benjamin Lee Whorf in 1940 pointed out, for example, that the Hopi language often differs from English in its need for words. It has one word to designate the kind of water in a lake or waterfall and another for the kind we drink; English uses water for both. On the other hand, Hopi has one word for flying things that covers what we designate with insect, airplane, and aviator. Trobriand Islanders have many words for sweet potatoes. Some South Pacific island languages have no general word meaning “tree”, but have separate words for varieties of palms. Our modem technology has added hundreds of words to the English vocabulary.
