一道game题

有人在做03Dec的Game吗？？

我做的有两道题和答案不一样，但又无法理解答案，希望哪位指点一下啊~~~

试题如下：

five students: JKLMO, each review one or more of three plays: S,T,U, but do not review any other plays.

1. K and L revew ferwer of the plasy than M.

2.Neither L nor M reviews any play J reviews.

3.K and O both review T.

4.Exactly two of the students review exactly he same play or plays as each other.

问题：

1. Which one of the folloing could be an accurate and complete list of the students who review only S?

a.L   b.O  c.J,L   d.K,O   e.L,M

2. If exactly three of the students review U, which one of the folloing could be true

a. M does not review U

b. O does not review U

c.J reviews U

d.L reviews T

e.O reviews S

1.a

2.b

谢谢楼上的回答~~我也琢磨半天。

1是选择a，我当时把accurate list想成了所有能只看S的，后来才明白是可以一起只看S的。

2的答案是E，是这种情况：

S   T   U

M   K   O

O   O   L

    J   M
