Critical Reasoning

I don't have a source for most of the questions. However, these questions are discussed on BTG in 2008. Hope that these are good for practice. Let me know if anyone knows the source, so that I will not post these questions

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. Therefore, 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.

13. The conclusion concerning words for colors would be properly draw if which one of the following were assumed?

(A) Most languages have distinct words for "sister" and "brother."
(B) Each language has a different basic word for each sensory quality that its speakers can perceptually distinguish.
(C) Every language makes some category distinctions that no other language makes.
(D) In any language short, frequently used words express categories that are important for its speakers to distinguish perceptually from each other.
(E) Speaker of languages with relatively few basic words for colors live in geographical regions where flora and fauna do not vary greatly in color.
