标题: 请问这道GAME是不是答案印错了呢?

Questions 1-7

  During a period of six consecutive days—day 1 through day 6—each of exactly six factories—F, G, H, J, Q, and R—will be inspected. During this period, each of the factories will be inspected exactly once, one factory per day. The schedule for the inspections must conform to the following conditions:

  F is inspected on either day 1 or day 6.

  J is inspected on an earlier day than Q is inspected.

  Q is inspected on the day immeditaely before R is inspected.

  If G is inspected on day 3, Q is inspected on day 5.

6. If the inspections of G and of H are scheduled, not necessarily in that order, for days as far apart as possible which one of the following is a complete and accurate list of the factories any one of which could be scheduled for in spection for day 1?

  (A) F, J
  (B) G, H
  (C) G, H, J
  (D) F, G, H
  (E) F, G, H, J

请教大家:我的这本资料上答案选(D)。

但我几次做下来都是(E),(E)与(D)的区别在于是否包含“J”,我觉得J可以放在1的位置(JGQRHF,满足全部条件),请问大家是不是答案印错了?

选D对的啊,要G和H as far as possible,只有两种情况: G、H=1、5, F=6 或者 F=1, G、H=2、6.
那么1的位置上就是G、H、F三种可能。
