In many languages other than English there is a word for "mother' s brother"which is different from the word for "father' s brother, " whereas English uses the word "uncle" for both. Thus, speakers of these languages evidence a more finely discriminated kinship system than English speakers do. The number of basic words for colors also varies widely from language to language. Ttherefore, speakers of languages that have fewer basic words for colors than English has must be perceptually unable to distinguish as many colors as speakers of English can distinguish. Which one of the following, if true, undermines the conclusion concerning words for colors? ['Khmer uses a basic word corresponding to English "blue"for most leaves, but uses its basic word corresponding to English "green" for unripe bananas', 'Speakers of English are able to distinguish between lighter and darker shades of the color they call "blue, "for which Russian has two different basic words.', 'The word "orange"in English has the same origin as the equivalent word in Spanish.', 'Almost every language distinguishes red from the other colors']
