In a recent experiment, a high school English teacher interspersed real, commonly used proverbs with several nonsensical proverbial-sounding statements that he had made up. He then asked his students to evaluate all of the statements on the list. In general, the students found the bogus proverbs and the real proverbs to be equally full of wisdom and meaning. The teacher concluded that proverbs attain their status as proverbs more through frequent usage than through their inherent wisdom. Which one of the following, if true, would most effectively challenge the teacher’s conclusion

B.There were more real proverbs than bogus proverbs in the list of statements.
C.There are stylistic differences between proverbial and proverbial-sounding statements.

E.(E) The students selected as evaluators were too inexperienced to judge the wisdom of the statements.
