来源:LSAT    发布时间:2013-01-02    LSAT辅导视频    评论

  在上节中,LSAT逻辑推理题目的图形解法 5, 线性逻辑, 我们熟悉了队列的线性问题, 现在我们再来看一个更复杂一点的类似问题。
  A camper counselor is holding yetherball practice for seven camper named F, G, H, I ,J K, L throughout this week starting from monday. each camper practiceonly once and only one camper will practice per day.
  A) F, and J will practice on either Tuesday or Satuready.
  B) H will practice day after F
  C) L will not practice either the day before or the day after F or J practice
  D) K will not prctice on the day immediately following the day that J practice
  We still use the similar diagram we used at LSAT逻辑推理题目的图形解法 5, 线性逻辑, for keeping the consistency.
  
  我们用 X 在线下表示 No。 条件 C 相当与:
  
  即 L 只能在 4,。
  Q1. if J prctice before L, then who will practice on Sunday?
  A) L
  B) G
  C) H
  D) I
  E) K
  从条件 C 知道 L 只能在 4, 而J prctice before L, 则 F 只能在 6, from B, 那就是 H 在 Sunday, 所以 答案是 C) H 。
  Q2, if K practice at Friday, then whi will practice on Thursday>
  A) K
  B) G
  C) I
  D) L
  E)H
  我们已经知道, L 只能在 4 ,所以这个条件是多余的, 不要怀疑自己,答案是 D) L . 所以开始的推导必须要认真, 把题目看清楚。
  Q3 Who of following who CANNOT practice on Monday orTuesday?
  A) I
  B) H
  C) F
  D) K
  E)G
  From the constrain B) H will practice day after F, 答案是 B) H.
  Q4。 If G and H practice before J, then who will practice on Sunday?
  A) I
  B) L
  C) K
  D) F
  E)G
  If G and H practice before J, so that theymust practie before Saturday, rule out G and H, F, J, and L, so only K could practice on Sunday, and K could not follow J who may be on Saturday, answer is A) I.
  Q5, if K practice third, then we know which days that how many people practice, including Kelly?
  A) 2
  B) 3
  C) 4
  D) 5
  E)5
  这句英语的意思是在K第三个出场, 也就是 在周三play 的条件下,有几个人的schedule?是确定的? K 不能 follow J,所以周二只能是 F play, so 我们知道 F, K, L, J的 schedule,
  answer isC) 4
  Q6, if G practice before J and J practice before L , then who will practice on Friday?
  A) J
  B) G
  C) K
  D) I
  E)F
  
  From the constrains , we have above diagram, only K and I left for , and 5, but K can not follow J on 3, so that K has to practice at Friday, answer is C) K. 考试大收集整理
