有一个停车场需要给六个新人安排趴车位：Ron, Sue, Tom, Vincent, Xie and Ying。每人只能在以下趴车位趴车：#1, #2, #3, #4, #5, #6，而且每人的趴车位都不同。以下是分配条例：
Ying 的车位号比 Tom 的大。
Xie 的车位号比 Sue 的大。
Ron 的车位号比 Ying 的大。
Ron 必须在 #1, #2, #3, 和 #4 之一趴车。

Analysis:
For all games, after reading the stimulus, you have to quickly diagram the information into an easy-to-read and efficient form. Analyze every rule first. Then combine the rules to make necessary deductions. If you end up with only 2 possible options for a particular game, you should draw out those two options. If more than 2, it's better to leave the rules as they are, without wasting time to draw every single possibility.

For this question, it's rather simple. Six players, six positions, no overlap. This is the easiest type in LSAT. Make sure you can move quickly through this one and try to limit your time spent for the whole game within 5 minutes. Pay extreme attention to the floater (the player having ZERO constraint, for example, V, in this game), and the most restricted player (R in this case). The final diagram can be found in the following picture:

Answers:

1) This is the simplest question, just apply rules one after another to each choice and eliminate wrong answers. Whoever left standing is the correct answer.
T-Y: A) is out
S-X: C) is out
Y-R: D) is out
R in 1-4: B) is out.

E) is the answer.

2. If S-T, then we got S-T-Y-R-(X/V), or frame 2. Scan the answer choice to eliminate Must be wrong answers, or pick the could-be-true answer. Either way, you get B).

3. To answer this question, just use brutal force of plug and play.
A) Wrong. X/V are not set.
B) Wrong. At least R could be in 3 or 4.
C) Correct. TYVRSX. Set.

4. We already know that R can ONLY be in 3 or 4. Then T can only be in 1 or 2; Y can only be in 2 or 3. Is that all? V is a floater. So V is not restricted to ONLY two. What about the pair of S and X? X has to be in either 5 or 6.

D) is correct.

5. (S/T)YR(X/V)

A) is correct.

6. TYR(S-X/V)

E) is correct.
