Complete Question Explanation
(The complete setup for this game can be found here: viewtopic.php?t=1171)

The correct answer choice is (E)

The question stem creates the following conditional relationship:

    L ..... :arrow: ..... P

This rule establishes that Z, which already has L, must also have P:

As Z has power windows, Z cannot have a sunroof and answer choice (E) is correct.

I understand why the answer choice is E, but I don't understand why A is wrong. T has power windows must be false, because if T has P than it must also have L according to the introduced rule of L --> P. If T has LP then T < Z rule is not satisfied.

Hi jwilia,
Careful, the rule says L --> P, but you have interpreted that to mean that L & P are always together. What the rule is saying is that if we know a car has L then it automatically gets P. But if we know a car has P we have no idea whether it will have L, that would be a Mistaken Reversal. So Answer A may be true, Car T might have P and no other options.
Hope that helps!
