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)
