Stimulus

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 be perceptually unable to distinguish as many colors as speakers of English can distinguish.

Answer choices

  1. Correct61% picked this

    Speakers of English are able to distinguish between lighter and darker shades of the color they call “blue, ” for which Russian

    Why this is right

    This shows that there's no automatic link between whether you have words for it and whether you can perceptually distinguish it. English has fewer words for "blue" than Russian has, but speakers of English can still distinguish between those two different Russian "blues" (lighter blue / darker blue). Thus, a language that has fewer colors than English would be in the same position that English speakers are compared to Russian speakers. Having fewer words apparently doesn't mean you are to distinguish fewer hues. This answer attacks the central assumption of the argument.

    Skill tested: Weaken · how this choice captures the argument's function is the move to repeat next time.

  2. No Impact3% picked this

    Almost every language distinguishes red from the

    This doesn't give us any way to argue that, "even if language X has fewer color words than language Y, that doesn't mean people who speak X can perceptually distinguish fewer colors than people who speak Y." It just says that almost all languages have a word for red.

  3. Unclear Impact21% picked this

    Khmer uses a basic word corresponding to English “blue” for most leaves, but uses its basic word corresponding to

    This answer isn't clearly about what people can / can't perceptually distinguish. It just sounds like Khmer has a color word that they use specifically with a fruit.

  4. No Impact4% picked this

    The word “orange” in English has the same origin as the equivalent

    This doesn't give us any way to argue that, "even if language X has fewer color words than language Y, that doesn't mean people who speak X can perceptually distinguish fewer colors than people who speak Y." It just says that the word for "orange" in two languages happens to have a similar root word.

  5. Unclear Impact11% picked this

    Most languages do not have a basic word that distinguishes gray from other colors, although gray is

    We might try to read this as, "See, author? Lots of language don't have a color word for gray even though they can perceptually distinguish gray (I mean, it is commonly found in nature)." That's a stretch, most importantly because we have an available answer in (A) that doesn't need us to make any such stretch on the answer's behalf. Here, we'd be thinking "commonly found in nature = people can perceptually distinguish that color"? But with (A), it was the more comfortable "able to distinguish between two shades = can perceptually distinguish two different colors".
