问题 The following data sufficiency problems consist of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are sufficient for answering the question. Using the data given in the statements plus your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of counterclockwise), you must indicate whether
   Ａ.  Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
   Ｂ.  Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
   Ｃ.  BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
   Ｄ.  EACH statement ALONE is sufficient.
   Ｅ.  Statements (1) and (2) TOGETHER are NOT sufficient. [br] N and P are points on the number line below 20. Is P closer to 10 than N is?
   (1) P is greater than the average of 10 and N.
   (2)
选项
答案 E
解析 Both statements alone and combined are insufficient, because, for example, the values (9, 3) for (P, N) meet all the conditions and yield an answer of "yes," while the values (18, 6) meet all the conditions and yield a "no."
